(R-01) +- **`safe_keys` preserves the entire subtree**, and the shipped profiles no + longer list `message`, `title`, `url`, `path`, `ip`, `user_agent`, `source` or + `target` as safe - all of them are free text or personal data, and with them + safe the values were emitted verbatim. `session_id` was listed as both safe + and blocked; it is now blocked only. (R-02) +- **Monolog integration moved to a processor.** Use + `Logging\RedactorTap` / `Logging\RedactorProcessor`, which redact message, + context and extra without touching the channel's output format. + `ReadactFormatter` still works and can now wrap an inner formatter. (R-06) +- **Scan findings are structured**: rule, line, column and a redacted excerpt, + instead of one opaque `full_content_redacted` record per file. (R-10) +- **Removed** `Redactor::addStrategy()`, `removeStrategy()`, + `calculateShannonEntropy()` and `isCommonPattern()`. The two useful ones are + now public on `ShannonEntropyStrategy`. (R-20) +- Invalid configuration now throws with the offending path named, instead of + silently falling back to a default. (R-09) + +### Fixed - correctness and security + +- Recursion is depth-bounded and cycle-aware. A self-referencing `toArray()` + used to exhaust memory and kill the process. (R-03) +- The logging path never throws. A bad profile no longer takes the channel down, + and diagnostics cannot re-enter the logger that raised them. (R-04) +- Scanner exclude patterns work. `vendor/*` and `node_modules/*` were passed to + `Finder::notName()`, which matches basenames, so they matched nothing and + every dependency was scanned. Binary files and gitignored files are skipped + too. (R-05) +- Redaction metadata no longer corrupts the payload: a list stays a list, and a + caller's own `_redacted` key is not overwritten. Prefer + `redactWithMetadata()`. (R-07) +- `safe_keys` supports the wildcards the README has always documented. (R-08) +- Documented environment variables take effect. `REDACTOR_MAX_OBJECT_SIZE` was + silently ignored and `REDACTOR_SCAN_MAX_FILE_SIZE` crashed the scan + command. (R-09) +- PCRE failures fail closed. `preg_match()` returning `false` was read as + "no match", so an errored pattern let the value through. (R-15) +- Entropy is measured per character, not per byte, and can be judged per + alphabet. The `aws_secret_key` pattern no longer matches any 40-character + alphanumeric run. (R-16) +- Checksum validators (`luhn`, `iban`, `ssn`) reject values of the right shape + that cannot be the real thing. (R-17) +- `mergeConfigFrom()` runs in `register()`, not `boot()`. (R-14) +- `ReadactFormatter::formatBatch()` formats every record; it used to return only + the first, so batching handlers dropped the rest. (R-06) + +### Added + +- `Redactor::redactWithMetadata()` returning a `RedactionResult`. (R-07) +- `Redactor::redactSafely()`, which never throws. (R-04) +- `php artisan redactor:validate` - resolves every profile and fails on the + broken ones, including keys listed as both safe and blocked.

(R-01, R-16, R-17) +- `max_depth` and `shannon_entropy.charset_thresholds` profile settings. + (R-03, R-16) +- `redactor:scan --output=sarif` for GitHub code scanning, and + `--baseline` / `--update-baseline` so CI fails only on new findings. (R-10) + +### Performance + +- Blocked-key matching compiles its pattern list once instead of rebuilding a + regex per key per call: 1.223 us -> 0.288 us per check. (R-12) +- Nested nodes are dispatched through the strategy chain once rather than + twice. (R-13) +- `Redactor` and `Scanner` are container singletons, so the strategy cache + survives. (R-11) +- Net effect on the default profile: ~15,000 -> ~21,000 redactions/sec, while + doing strictly more work than before. + +### Packaging and CI + +- PHP 8.5 supported and in the test matrix. (R-21) +- `Tests\` no longer ships in the production autoload; `.gitattributes` keeps + development files out of the dist archive. (R-18) +- Dropped the unused `spatie/laravel-package-tools` requirement and declared + `symfony/finder` and `monolog/monolog`, which the package uses directly. (R-19) +- Coverage floor, Infection mutation testing, a performance regression suite, + and `failOnWarning`/`failOnRisky`/`failOnDeprecation` in phpunit.xml.

Features a class-based strategy system with profile-based configurations, Shannon entropy detection. - -> This package is in active development and its API can change abruptly without any notice. Please reach out if you plan to use it in a production environment. +Redactor removes sensitive data from anything a Laravel application emits before it leaves: log records, HTTP responses, streamed output, MCP tool results, prompts sent to a language model, exports and queued jobs. It finds sensitive values by the key they sit under, by what they look like (credential patterns with checksum validators, Shannon entropy, an optional named entity recogniser) and by where they live in a payload, then replaces only the sensitive span so the text around it survives. +What replaces a value is a separate, per-entity decision. The same email address can become `[REDACTED]` in an audit log, a stable pseudonym like `u_7f3ac9@customer.com` in an application log so counts and joins still work, or a reversible token like `tok_email_k4m9rp2xzq` in front of a model so the application can act on the answer. Profiles bundle the rules and the decisions, and every boundary takes a profile name. The same engine scans files and git history from `redactor:scan`, with SARIF output, baselines and optional live-credential verification. ## Quick Start +Install the package and publish its configuration: + ```bash composer require kirschbaum-development/redactor php artisan vendor:publish --tag=redactor-config ``` -The package automatically registers the service provider and facade.

The regex and entropy strategies -are *detectors*: they report what they found and where, and change nothing. -Once every detector has seen the value, the context resolves their reports and -rewrites the original string once. Three things follow from that: - -- An API key sitting next to an email address is not spared because the email - matched first - both are reported, both are rewritten. -- A surrogate written for one detection is never re-detected by the next - detector. It has the same shape and entropy as the value it replaced, and a - sequential chain would have redacted it again. -- Every finding's offset is an offset into the value you passed, so the scanner - reports the right column for the second secret on a line. - -Where two detections overlap, the higher score wins - a Luhn-validated card -outranks the bare digit run that also matched it. On an equal score the rule -listed first wins, so `url_with_auth` declared ahead of `email` takes the -password out of `https://user:pass@host` and leaves the host. - -Two of them are special: - -- `SafeKeysStrategy` **preserves** rather than redacts. It ends the chain *and* - stops the walk, so everything nested under a safe key is emitted untouched. - Only list keys whose contents cannot carry sensitive data by construction - - identifiers, timestamps, enumerations. A free-text field like `message` is not - safe just because it usually looks harmless. -- Every regex is evaluated fail-closed. If PCRE gives up on a pattern - backtrack - limit, JIT stack limit, bad UTF-8 - the value is treated as sensitive rather - than clean, and the failure is logged with the rule name. - -### Profiles - -Profiles provide different redaction configurations for different contexts: - -```php -// Use built-in profiles -$logData = Redactor::redact($data, 'default'); // Balanced redaction -$auditData = Redactor::redact($data, 'strict'); // Aggressive redaction -$debugData = Redactor::redact($data, 'performance'); // Minimal redaction for speed -``` - -## Configuration - -The config file (`config/redactor.php`) uses a class-based approach: - -```php -return [ - 'default_profile' => 'default', - - 'profiles' => [ - 'default' => [ - 'enabled' => true, - - // Strategies executed in array order (top-to-bottom priority) - 'strategies' => [ - \Kirschbaum\Redactor\Strategies\SafeKeysStrategy::class, - \Kirschbaum\Redactor\Strategies\BlockedKeysStrategy::class, - \Kirschbaum\Redactor\Strategies\LargeObjectStrategy::class, - \Kirschbaum\Redactor\Strategies\LargeStringStrategy::class, - \Kirschbaum\Redactor\Strategies\RegexPatternsStrategy::class, - \Kirschbaum\Redactor\Strategies\ShannonEntropyStrategy::class, - ], - - 'safe_keys' => ['id', 'user_id', 'uuid', 'created_at', 'updated_at'], - 'blocked_keys' => ['password', 'secret', 'token', 'api_key', 'authorization'], - 'patterns' => [ - // The shipped config defines two lists at the top of the file - // and spreads them into every profile, so the profiles cannot - // drift apart. $credentialPatterns: credential URLs, PEM - // blocks, JWTs, bearer tokens, and AWS, GitHub, Stripe, Slack, - // OpenAI, Anthropic, Google and SendGrid keys. - // $identityPatterns: emails, phones, SSNs, cards and IBANs. - ...$credentialPatterns, - ...$identityPatterns, - - // Shorthand: matched span replaced with the replacement string - 'internal_id' => '/\bINT-\d{8}\b/', - - // Full rule form - see "Pattern Rules" below - 'credit_card' => [ - 'pattern' => '/\b(?:\d[ -]*?){13,16}\b/', - 'validator' => 'luhn', // reject non-cards of the same shape - 'entity' => 'credit_card', - 'keywords' => [], // literals that must be present first - ], - ], - 'replacement' => '[REDACTED]', - 'mark_redacted' => true, - 'track_redacted_keys' => false, - 'non_redactable_object_behavior' => 'preserve', // 'preserve', 'remove', 'redact', 'empty_array' - 'max_value_length' => 5000, - 'large_string_behavior' => 'truncate', // keep the head and scan it; 'redact' replaces the value - 'redact_large_objects' => true, - 'max_object_size' => 100, - 'max_depth' => 32, // guards cyclic and pathologically nested payloads - - 'shannon_entropy' => [ - 'enabled' => true, - 'threshold' => 4.8, // Higher = more selective - 'min_length' => 25, // Only analyze strings this long or longer - - // Per-alphabet thresholds.

Every shipped rule carries -both. - -### Dictionary rules - -A rule can be a list of words instead of a regex. Product codenames, internal -project names, a customer list: things no pattern can express and no model -would know. - -```php -'codenames' => ['words' => ['Project Falcon', 'Orion'], 'entity' => 'codename'], -``` - -Words are matched whole and case-insensitively, longest first, so `Project -Falcon` is one finding rather than two and `Orionids` is left alone. - -### Allow-lists - -Some values look sensitive and are known not to be: the support address on -every page, the sandbox card in every fixture, the example key in the docs. -List them rather than weakening the pattern that finds them: - -```php -'allowlist' => [ - 'noreply@example.com', // a literal, compared case-insensitively - '/^test-\d+@example\.com$/', // or a regex -], -``` - -The allow-list is checked after detection, whichever detector reported the -value - a pattern, entropy, a blocked key or a path rule - so the rules stay as -strong as they were written and an allowed value is simply not a finding. A -regex entry that cannot be evaluated allows nothing. - -A rule can carry its own exceptions, scoped to that rule alone: - -```php -'email' => ['pattern' => EMAIL, 'allow' => ['/@example\.com$/']], -``` - -## Known Secrets - -Every other detector infers. This one knows: the application's own credentials -are already in config, and a log line containing one of them verbatim is a leak -whatever it looks like. - -```php -'known_secrets' => [ - 'values' => [env('LEGACY_SIGNING_KEY')], - 'config' => [ - 'app.key', // shipped default - 'services.stripe.secret', - 'database.connections.mysql.password', - 'services.acme', // an array: every string under it - ], -], -``` - -Matching is exact and case-sensitive. Values under eight characters and nulls -are skipped, so an unset secret in a local environment never fails the profile. -A credential that only exists at runtime is registered the same way: - -```php -Redactor::registerSecret($vault->read('signing-key')); -``` - -## Entity Recognition - -Names, addresses and organisations are the PII no regex can express and no -entropy measure can see. A named entity recogniser can find them, at a cost -three orders of magnitude above the rule engine, so the package treats it as -a gated extra rather than a default. - -The recogniser speaks Presidio's `/analyze` contract - text in, a list of -`{entity_type, start, end, score}` out - so the reference Presidio analyzer, -the same analyzer with a transformer recogniser, or a small wrapper around any -fine-tuned model all work without a line of PHP: - -```php -'recognition' => [ - 'enabled' => true, - 'driver' => 'presidio', - 'url' => 'http://presidio:5002/analyze', - 'entities' => ['PERSON', 'LOCATION', 'ORGANIZATION'], - 'entity_map' => ['PERSON' => 'person', 'LOCATION' => 'location'], - 'score_threshold' => 0.6, -], - -'operators' => [ - 'person' => 'surrogate', - 'location' => 'redact', -], -``` - -What the gate does: - -- Only values that read as prose, between `min_length` and `max_length`, are - sent. A JSON blob, a stack trace or a bare token is not something a model - reads well, and its guesses would be the false positives the gate exists to - prevent. -- Only the labels listed, at or above `score_threshold`, become findings. -- Every span comes back in character offsets and is converted to bytes and - checked against the value before it is replaced. A span that does not line - up is skipped, never guessed. -- A recogniser that fails is skipped and the output is rules-only. After - `failure_threshold` consecutive failures it is not asked again for - `cooldown` seconds, so a dead sidecar costs one timeout, not one per log - line. -- Recognised spans go through the same overlap resolution, confidence floor - and operators as everything else. A `person` becomes a stable surrogate - exactly the way an email does. - -Enable it on the profiles used from queues, exports and scans, not on the -request path. To plug in something that does not speak the Presidio contract, -implement `Recognition\Recognizer` and register it: - -```php -Redactor::registerRecognizer(new MyOnnxRecognizer); // then 'driver' => 'my-onnx' -``` - -## Path Rules - -A path says exactly where a value lives. Every other rule in this package is -inferring that from a key name or from the contents. - -```php -'paths' => [ - 'request.headers.authorization' => 'redact', - 'user.*.email' => 'surrogate', - '**.password' => 'redact', - 'users[*].token' => 'redact', - 'debug' => 'preserve', -], -``` - -| Segment | Matches | -| --- | --- | -| `literal` | that key exactly, case-insensitively | -| `*` | any single level | -| `**` | any depth, including none | -| `[*]` | a list index; `users[*].x` and `users.*.x` are the same | - -Paths are checked first and, when one matches, *instead of* everything else — no -key matching, no pattern scanning, no walk below the matched node. The more -specific pattern always wins, so declaration order never matters, and `preserve` -carves an exception out of a broader rule without disabling it. - -They compile once into a trie that is walked in lockstep with the payload, so -the cost tracks the rules currently in play rather than the number configured. -Two hundred path rules cost about the same as one. - -## Operators - -Detection asks "is this sensitive". An operator answers "so what". They are -separate because the right answer differs by context for the very same value. - -```php -'operators' => [ - 'default' => 'redact', - 'email' => ['surrogate' => ['preserve_domain' => true]], - 'credit_card' => ['partial' => ['keep' => 4]], -], -``` - -| Operator | Result | -| --- | --- | -| `redact` | `[REDACTED]` | -| `mask` | `****************` — length preserved | -| `partial` | `************1111` — last N kept | -| `remove` | deleted | -| `hash` | `[email:k4m9rp2xzq]` — stable, obviously not real | -| `surrogate` | `u_7f3ac9@customer.com` — stable, same shape | -| `nullify` | `null` — the key stays, a typed field stays typed | -| `preserve` | detected and reported, unchanged | - -Precedence runs most specific first: the path it was found at, then the entity -it is, then the rule that found it, then the profile default. Entity beats rule -deliberately — "every email here becomes a surrogate" is a policy decision about -data, and which regex spotted it is an implementation detail. - -Every detector goes through the same policy. A value found by its key uses the -key name as its entity, so `operators.email` applies to `['email' => ...]` and -to an address inside a message alike, and both produce the same surrogate. A -high-entropy token has the entity `high_entropy`. A `preserve` operator reports -the finding through `inspect()` without marking the payload redacted, -which is what a scan that should only report wants. - -Register your own with `Redactor::registerOperator('tokenize', $operator)` and -use it from config by name. - -## Pseudonymisation - -Replacing every value with `[REDACTED]` collapses distinct values into one, -which destroys the questions logs exist to answer: how many users hit this, is -it always the same account, did this session span both services. - -`surrogate` and `hash` replace a value with a *stable* stand-in instead. The -same input always produces the same output, so counts, joins and traces survive: - -```php -Redactor::redact('login by alice@customer.com', 'observability'); -// 'login by u_7f3ac9@customer.com' - -Redactor::redact('logout for alice@customer.com', 'observability'); -// 'logout for u_7f3ac9@customer.com' <- same surrogate, still joinable -``` - -Surrogates preserve shape, so anything downstream that parses the value keeps -parsing it: - -| Original | Surrogate | -| --- | --- | -| `alice@customer.com` | `u_7f3ac9@customer.com` | -| `4111 1111 1111 1111` | `4111 1193 7420 8846` — Luhn-valid, BIN kept | -| `sk_live_4eC39HqLyj` | `sk_live_9mB71TzKnQ` | -| `+1 (555) 867-5309` | `+7 (204) 331-8874` | - -The mapping is one-way — HMAC, not encryption. There is no route from a -surrogate back to the original, and anyone holding the key can confirm a guess, -so **the key must not travel with the logs**. Leave `redactor.pseudonymization.key` -null to derive one from `APP_KEY` (never used directly). Rotating it changes -every surrogate, which is how you deliberately break correlation with logs -already exported. - -Without a usable key, `surrogate` and `hash` fall back to plain redaction rather -than emitting an unkeyed stand-in that would look joinable and silently not be. - -Surrogates are the same on every profile, so an audit channel on `strict` and an -application channel on `observability` can still be joined on the same user. A -profile that must not be linkable back sets its own salt: - -```php -'export' => [ - 'pseudonymization' => ['salt' => 'export-2026'], - // ... -], -``` - -The shipped `observability` profile is set up for this. - -### Reversible tokens - -A surrogate is one-way. A token is a surrogate the *application* can exchange -back, which is what the boundary in front of a language model needs: the model -sees `tok_email_k4m9rp2xzq`, refers to it in its answer, and the application -resolves it before acting. - -```php -'operators' => ['email' => 'tokenize', 'credit_card' => ['tokenize' => ['ttl' => 600]]], -``` - -```php -$prompt = Redactor::redact($ticket, 'ai'); // 'reply to tok_email_k4m9rp2xzq about ...' -$answer = $llm->complete($prompt); // the model reasons about the token -$action = Redactor::detokenize($answer); // 'reply to alice@customer.com about ...' -``` - -Tokens are derived with the pseudonymisation key, so they are stable and -cannot be guessed. Originals are kept in the cache, encrypted with the -application key, for `redactor.tokenization.ttl` seconds; a token the store no -longer knows, or one a model invented, is left exactly as it is. Anyone holding -the cache and the application key can resolve tokens, which is the trust the -application itself already carries. - -## Confidence - -Binary matching forces a choice between noise and misses: the only way to quieten -a rule is to weaken its regex everywhere. Detections carry a score instead. +Add the tap to a log channel in `config/logging.php`. It pushes a Monolog processor, so the channel keeps its own formatter: ```php -'patterns' => [ - 'card' => ['pattern' => '/\b\d{16}\b/', 'confidence' => 0.3, 'validator' => 'luhn'], +'stack' => [ + 'driver' => 'stack', + 'channels' => explode(',', env('LOG_STACK', 'single')), + 'tap' => [Kirschbaum\Redactor\Logging\RedactorTap::class], ], - -'min_confidence' => 0.5, -``` - -The base score comes from the rule; a passing checksum and a credential keyword -beside the match raise it. So the same pattern is filtered out as noise on its -own and reported when something corroborates it — without editing the pattern. - -Entropy detections are scored the same way: medium on their own, higher the -further the token sits above its threshold, and higher again beside a keyword. -A value found by its key is certain. `min_confidence` applies to all of them. - -Every finding explains itself: - -```json -{ - "rule": "card", - "confidence": 0.87, - "severity": "medium", - "signals": [ - "base +0.30 (pattern \"card\" matched)", - "validator +0.75 (luhn checksum passed)", - "context +0.25 (a credential keyword appears alongside the match)" - ] -} -``` - -## Wildcard Patterns - -The `BlockedKeysStrategy` and `SafeKeysStrategy` support powerful wildcard patterns using the `*` character. This allows you to match multiple key variations without listing each one explicitly. - -### Basic Wildcard Usage - -```php -// config/redactor.php -'profiles' => [ - 'wildcard_example' => [ - 'enabled' => true, - 'strategies' => [ - \Kirschbaum\Redactor\Strategies\BlockedKeysStrategy::class, - ], - 'blocked_keys' => [ - '*token*', // Matches any key containing "token" - '*key*', // Matches any key containing "key" - 'password', // Exact match (no wildcards) - 'user_*_data', // Matches keys like "user_profile_data", "user_settings_data" - ], - // ... other config - ], -]; - -// Usage example -$data = [ - 'user_id' => 123, - 'api_token' => 'secret123', // Matched by *token* - 'access_token' => 'abc123', // Matched by *token* - 'my_custom_token' => 'xyz789', // Matched by *token* - 'user_api_key' => 'key123', // Matched by *key* - 'private_key_data' => 'private', // Matched by *key* - 'password' => 'secret', // Matched by exact "password" - 'user_profile_data' => 'profile', // Matched by user_*_data - 'user_settings_data' => 'settings', // Matched by user_*_data - 'normal_field' => 'safe_value', // Not matched - preserved -]; - -$redacted = Redactor::redact($data, 'wildcard_example'); -``` - -### Wildcard Pattern Types - -#### Contains Pattern (`*word*`) -Matches any key that contains the specified word anywhere: - -```php -'blocked_keys' => ['*token*', '*secret*', '*auth*'], - -// Matches: -// - api_token, access_token, token_data, my_token_field -// - user_secret, secret_key, app_secret_config -// - auth_header, oauth_token, authentication_data -``` - -#### Prefix Pattern (`word*`) -Matches any key that starts with the specified word: - -```php -'blocked_keys' => ['password*', 'secret*', 'api*'], - -// Matches: -// - password, password_hash, password_confirmation -// - secret, secret_key, secret_data -// - api, api_key, api_token, api_endpoint ``` -#### Suffix Pattern (`*word`) -Matches any key that ends with the specified word: - -```php -'blocked_keys' => ['*token', '*key', '*secret'], - -// Matches: -// - access_token, api_token, user_token -// - private_key, public_key, encryption_key -// - user_secret, app_secret, database_secret -``` - -#### Multi-Wildcard Patterns (`word*middle*word`) -Use multiple wildcards for complex patterns: - -```php -'blocked_keys' => [ - 'user_*_token', // user_api_token, user_auth_token - 'app_*_*_key', // app_private_encryption_key, app_public_signing_key - '*_key_*', // my_key_data, the_key_value, user_key_config -], -``` - -### Case-Insensitive Matching - -All wildcard patterns are case-insensitive by default: - -```php -'blocked_keys' => ['*TOKEN*'], - -// Matches all of these: -// - API_TOKEN, api_token, Api_Token, MyTokenData, user_token_field -``` - -### Combining Exact and Wildcard Patterns - -You can mix exact matches with wildcard patterns in the same configuration: - -```php -'blocked_keys' => [ - 'password', // Exact match - 'secret', // Exact match - '*token*', // Wildcard pattern - '*_key_*', // Complex wildcard - 'user_*_data', // Specific structure -], - -'safe_keys' => [ - 'id', // Exact match - always preserved - 'user_id', // Exact match - always preserved - '*_count', // Wildcard pattern - preserve counting fields - 'meta_*', // Wildcard pattern - preserve metadata fields -], -``` - -### Performance Considerations - -Pattern lists are compiled once and cached, with each pattern sorted into the -cheapest test for its shape - a hash lookup for exact names, `str_contains` for -`*word*`, `str_starts_with`/`str_ends_with` for one-sided wildcards. Only -multi-wildcard patterns like `user_*_token` reach PCRE. - -In practice that means the shape of your list barely matters. If you are tuning -a very large one, prefer exact names and single-wildcard patterns over -multi-wildcard ones. - -## Common Use Cases - -### Logging Context +Redact anything else directly: ```php use Kirschbaum\Redactor\Facades\Redactor; -// Before logging user actions -Log::info('User action', Redactor::redact([ +Redactor::redact([ 'user_id' => 123, - 'action' => 'login', - 'ip_address' => '192.168.1.1', - 'session_token' => 'abc123def456...', - 'user_agent' => 'Mozilla/5.0...', - 'api_response' => $sensitiveApiData, -])); -``` - -### Laravel Logging Integration - -Add the tap to any channel in `config/logging.php`: - -```php -'channels' => [ - 'stack' => [ - 'driver' => 'stack', - 'channels' => explode(',', env('LOG_STACK', 'single')), - 'ignore_exceptions' => false, - 'tap' => [Kirschbaum\Redactor\Logging\RedactorTap::class], - ], - - 'single' => [ - 'driver' => 'single', - 'path' => storage_path('logs/laravel.log'), - 'level' => env('LOG_LEVEL', 'debug'), - 'tap' => [Kirschbaum\Redactor\Logging\RedactorTap::class], - ], - - // Pass a profile name after a colon to override the default - 'audit' => [ - 'driver' => 'daily', - 'path' => storage_path('logs/audit.log'), - 'tap' => [Kirschbaum\Redactor\Logging\RedactorTap::class.':strict'], - ], -], -``` - -`RedactorTap` registers a Monolog **processor**, which redacts the record's -message, context and extra and then leaves the channel's own formatter alone - -so a channel writing JSON keeps writing JSON. - -Redaction in the log path never throws. A profile name typo, an unreadable -config value or a strategy that blows up on unexpected input all fail *closed*: -the content is replaced rather than emitted, and logging keeps working. Validate -your profiles at deploy time so you find out earlier: - -```bash -php artisan redactor:validate -``` - -#### Formatter alternative - -`RedactorFormatter` is still available for channels that want a self-contained -drop-in. It owns the output format, so prefer the tap unless you specifically -want that. It can wrap an inner formatter rather than replace it: - -```php -use Kirschbaum\Redactor\Logging\RedactorFormatter; -use Monolog\Formatter\JsonFormatter; - -$handler->setFormatter(new RedactorFormatter(new JsonFormatter)); -``` - -### API Response Sanitization - -```php -use Kirschbaum\Redactor\Facades\Redactor; - -// Before returning debug information -return response()->json([ - 'debug' => Redactor::redact($requestData, 'performance'), - 'status' => 'processed' + 'password' => 'hunter2', + 'email' => 'bob@example.com', + 'note' => 'card 4111 1111 1111 1111 on file', ]); -``` -### Database Export & Auditing - -```php -use Kirschbaum\Redactor\Facades\Redactor; - -// Before exporting user data -$users = User::all()->map(function ($user) { - return Redactor::redact($user->toArray(), 'strict'); -}); - -// Audit trail with sensitive data redacted -$auditLog = Redactor::redact([ - 'user_id' => $user->id, - 'changes' => $changes, - 'request_data' => request()->all(), -], 'audit'); +// [ +// 'user_id' => 123, +// 'password' => '[REDACTED]', +// 'email' => '[REDACTED]', +// 'note' => 'card ***************1111 on file', +// '_redacted' => true, +// ] ``` -### PCI Compliance Example +Ask what was found rather than reading it back out of the payload: ```php -// config/redactor.php -'profiles' => [ - 'pci_compliant' => [ - 'enabled' => true, - 'strategies' => [ - \Kirschbaum\Redactor\Strategies\SafeKeysStrategy::class, - \Kirschbaum\Redactor\Strategies\BlockedKeysStrategy::class, - \Kirschbaum\Redactor\Strategies\RegexPatternsStrategy::class, - ], - 'safe_keys' => ['order_id', 'customer_id', 'amount', 'currency'], - 'blocked_keys' => [ - 'credit_card', 'cc_number', 'card_number', 'pan', - 'cvv', 'cvc', 'cvn', 'expiry', 'exp_date', 'security_code' - ], - 'patterns' => [ - 'credit_card' => '/\b(?:\d[ -]*?){13,16}\b/', - 'ssn' => '/\b\d{3}-?\d{2}-?\d{4}\b/', - 'routing_number' => '/\b\d{9}\b/', - ], - 'replacement' => '[PCI_REDACTED]', - 'non_redactable_object_behavior' => 'redact', - ], -]; +$result = Redactor::profile('strict')->withoutMarkers()->inspect($data); -// Usage -$orderData = Redactor::redact($order->toArray(), 'pci_compliant'); +$result->value; // the redacted payload +$result->wasRedacted; // true +$result->redactedKeys; // ['password', 'email'] +$result->findings; // rule, entity, key, offset, length and confidence for each match ``` -## Advanced Features - -### Object Handling +## How It Works -The package handles various object types: +A **profile** is one complete configuration: the strategies to run, the keys that are safe or blocked, the patterns to look for, and what to do with what is found. Five ship: `default`, `strict`, `observability`, `file_scan` and `performance`. Every entry point takes a profile name, so the same value can be pseudonymised on one channel and removed on another. -```php -use Kirschbaum\Redactor\Facades\Redactor; +**Strategies** run in the order the profile lists them. Key rules decide by the name a value sits under; pattern rules, known secrets, entropy and entity recognition decide by content and report what they found and where; path rules decide by location and are checked before anything else. Detections are resolved once, so two rules matching the same text produce one rewrite and a surrogate written for one detection is never re-detected by the next. -// Laravel models (uses toArray()) -$user = User::find(1); -$redacted = Redactor::redact($user); - -// Plain objects (uses JSON serialization) -$object = new stdClass(); -$object->secret = 'sensitive'; -$redacted = Redactor::redact($object); - -// Throwables, DateTimeInterface, DateTimeZone, enums and closures pass -// through untouched: a Throwable has nothing to inspect and the formatter -// needs the object to render the trace. Key rules still apply to them. -Log::error('failed', ['exception' => $e, 'password' => 'x']); -// ['exception' => $e, 'password' => '[REDACTED]'] - -// Non-serializable objects (configurable behavior) -$resource = fopen('file.txt', 'r'); -$redacted = Redactor::redact(['file' => $resource]); -// Behavior controlled by 'non_redactable_object_behavior' setting -``` - -### Custom Strategies - -Create your own redaction logic with full type safety: +**Operators** decide what replaces a detection, per entity rather than per rule: ```php -use Kirschbaum\Redactor\Strategies\Contracts\Strategy; -use Kirschbaum\Redactor\RedactionContext; - -class InternalDataStrategy implements Strategy -{ - public function shouldHandle(mixed $value, string $key, RedactionContext $context): bool - { - return str_contains($key, 'internal_') || str_contains($key, 'debug_'); - } - - public function handle(mixed $value, string $key, RedactionContext $context): mixed - { - // recordRedaction() also reports the key and rule to the caller and to - // the scanner; markRedacted() only sets the flag. - $context->recordRedaction($key, 'internal_data'); - - return '[INTERNAL]'; - } -} - -// Register and use -use Kirschbaum\Redactor\Facades\Redactor; - -Redactor::registerCustomStrategy('internal_data', new InternalDataStrategy()); - -// Add to profile configuration -'strategies' => [ - 'internal_data', // Custom strategy by registered name - \Kirschbaum\Redactor\Strategies\SafeKeysStrategy::class, - // ... other strategies +'operators' => [ + 'default' => 'redact', // [REDACTED] + 'email' => ['surrogate' => ['preserve_domain' => true]], // u_7f3ac9@customer.com, stable + 'credit_card' => ['partial' => ['keep' => 4]], // ************1111 + 'ssn' => 'nullify', // null, so a typed field stays typed ], ``` -### Multiple Usage Patterns - -```php -// Via Facade (recommended) -use Kirschbaum\Redactor\Facades\Redactor; -$result = Redactor::redact($data, 'profile_name'); - -// Via Service Container -$redactor = app(\Kirschbaum\Redactor\Redactor::class); -$result = $redactor->redact($data, 'profile_name'); - -// Direct instantiation (a fresh instance with its own strategy cache; -// the container binding is a singleton) -$redactor = new \Kirschbaum\Redactor\Redactor(); -$result = $redactor->redact($data, 'profile_name'); - -// Check available profiles -$profiles = Redactor::profiles(); -$exists = Redactor::hasProfile('custom_profile'); -``` - -## HTTP Responses - -Data that leaves through an API needs the same boundary as data that leaves -through a log. The `redact` middleware redacts a response before it is sent, -with a profile per route: - -```php -Route::get('/export', ExportController::class)->middleware('redact:observability'); -Route::get('/me', MeController::class)->middleware('redact'); -``` - -JSON responses are redacted as data, so structure and types survive; text -responses are redacted as text; file responses pass through. The profile's -`_redacted` markers are never written into a response. Where a consumer has -typed the field - an API contract, MCP structured content - use `nullify` so -the field stays a field and keeps its type: - -```php -'operators' => ['ssn' => 'nullify', 'age' => 'nullify'], -``` +`surrogate`, `hash` and `tokenize` are keyed with an HMAC derived from `APP_KEY` (or a key of your own), so the same input always yields the same stand-in and logs stay joinable without a route back to the original. -The middleware fails closed: a response that cannot be redacted becomes a 500 -with none of the original body, not the original body. Run `redactor:validate` -at deploy time so that never happens in production. - -### Streams - -A streamed response - server-sent events, a model's tokens, a file piped -through - is redacted as it streams. The middleware wraps the callback; for -anything else, wrap the chunks yourself: - -```php -use Kirschbaum\Redactor\Streaming\StreamRedactor; - -$stream = new StreamRedactor(app(Redactor::class), 'observability'); - -foreach ($stream->through($llm->tokens()) as $safe) { - echo $safe; // emitted only once it cannot be half a secret -} - -return $stream->response(fn () => $this->export($rows)); // a StreamedResponse -``` - -The last kilobyte of input (configurable) is held back until more arrives, so a -secret split across two chunks is still caught, and the cut always falls on a -line end - or, when a stream goes a whole window without one, a word boundary. -An open PEM block is held whole. The cost is latency in bytes, not time. - -## MCP Servers - -An MCP server hands data straight to a model. With Laravel's MCP package, -one trait redacts everything the server returns, over HTTP or stdio: tool -results, structured content, resource reads, prompt messages, streamed tool -output and error messages. Binary content and the protocol envelope are left -alone. - -```php -use Kirschbaum\Redactor\Mcp\RedactsResponses; - -class SupportServer extends Server -{ - use RedactsResponses; - - protected function redactionProfile(): ?string - { - return 'observability'; // or a profile that tokenises, see below - } -} -``` - -It sits where the server builds its responses, so the package's own test -helpers exercise it: `SupportServer::tool(LookupCustomer::class)->assertDontSee($email)`. - -## AI Agents - -With Laravel's AI package, the `RedactPrompt` middleware redacts a prompt -before the provider sees it and resolves tokens in the answer on the way back: - -```php -use Kirschbaum\Redactor\Ai\RedactPrompt; - -class SupportAgent extends Agent implements HasMiddleware -{ - public function middleware(): array - { - return [RedactPrompt::using('ai')]; - } -} -``` - -With a profile whose operators tokenise, the model reasons about -`tok_email_k4m9rp2xzq` and the application receives the real address back in -the response text. With a profile that redacts outright, the model never sees -the value. Pass `detokenizeResponse: false` to keep tokens in the answer. - -## Events - -Every redaction that changed something dispatches `RedactionPerformed` with -the profile, the keys, and counts per rule and per entity, and never a value, -so a listener can feed metrics or an audit trail without becoming a leak.

A credential URL in a -JSON file reads `https:\/\/user:pass@host`, a key in a Kubernetes secret is -base64, a token in a query string is percent-encoded. The scanner decodes -those, one layer deep, and scans what comes out; a finding says which encoding -hid it and its excerpt is taken from the decoded, redacted text. Switch it off -with `REDACTOR_SCAN_DECODE=false`. Redaction of live payloads does not decode: -that is a cost on every log line for a case the scanner is the right place to -catch. - -### Scanning changes, not files - -A gate on commits cares about what is being added, not what was already -there. Three modes scan only the lines a change adds, so a pre-existing finding -never blocks a commit and a secret is caught on the line that introduces it: - -```bash -php artisan redactor:scan --staged # what is about to be committed -php artisan redactor:scan --diff=origin/main # what this branch adds over main -php artisan redactor:scan --history # every line every commit ever added -php artisan redactor:scan --history=main..HEAD app/ # a range, and a pathspec -``` - -History mode finds a secret that a later commit removed: it is still in the -repository. Each finding names the commit that added it. - -### As a gate - -Publish the hook and the workflow: - -```bash -php artisan vendor:publish --tag=redactor-ci -git config core.hooksPath .githooks -``` +- **Log channels** through `RedactorTap`, which never throws: a broken profile replaces the record rather than taking the channel down. +- **HTTP responses** through the `redact` middleware: JSON as data, text as text, streams as they stream, files untouched, failing closed to a 500. +- **Streams** through `StreamRedactor`, which holds back a window so a secret split across two chunks is still caught. +- **MCP servers** through the `RedactsResponses` trait on a Laravel MCP server: tool results, structured content, resources, prompts, streamed output and errors. +- **AI agents** through the `RedactPrompt` middleware for Laravel's AI package: the prompt is redacted on the way out and tokens are resolved in the answer. +- **Exports, jobs, error reporters and third-party clients** through `Redactor::redact()` and `redactSafely()` with a profile per destination. +- **Files and git history** through `redactor:scan`, with table, JSON, SARIF and JUnit output, `--staged`, `--diff` and `--history` modes, baselines, inline `redactor:allow` markers, and a publishable pre-commit hook and GitHub workflow. +- **Your test suite** through `Redactor::fake()`, so a test can assert that a secret never left. -The hook runs `redactor:scan --staged --bail` before every commit. The -workflow scans a pull request's changes over its base and uploads SARIF, and -scans the whole tree against the baseline on `main`. `--output=junit` produces -JUnit XML for a CI dashboard that already renders test results: one test case -per file, one failure per finding, with the excerpt already redacted. +## Documentation -Files that are binary, larger than `max_file_size`, matched by an exclude -pattern, or already ignored by git are skipped. Everything else is read as -overlapping windows of lines, so memory stays flat whatever the file size — the -files most worth scanning are the large ones. Windows overlap so a secret -spanning a boundary (a PEM block, a wrapped connection string) is still found. +The full documentation lives in [`docs/`](docs/README.md): -### Confidence filtering - -```bash -php artisan redactor:scan --min-confidence=0.8 -``` - -Raises the bar without weakening any pattern. Each finding reports its score, -its severity and the signals behind it, so the threshold can be chosen on -evidence. - -### Verifying credentials - -A scan of a mature repository turns up hundreds of candidates — expired keys, -examples in docs, fixtures, rotated credentials — and a list that cannot -separate the live ones from the dead is a list nobody triages. Verification asks -each provider directly. - -It also sends real secrets to third parties, so nothing happens unless all three -of these agree: - -```php -// config/redactor.php — reviewable in a diff -'verification' => [ - 'enabled' => true, - 'verifiers' => ['github_token', 'stripe_key', 'slack_token'], -], -``` - -```bash -php artisan redactor:scan --verify # and a human, per run -``` - -An empty `verifiers` list means none: enabling the feature and choosing who to -trust with the secrets are separate decisions. The command names every host it -will contact before it contacts any of them. Redaction itself can never trigger -this — only the scan command can, because nothing running unattended inside an -application should be making outbound calls with secrets in them. - -A confirmed-live credential is ranked `LIVE` above everything else. A check that -could not complete stays `high`, not `low`: failing to verify is not evidence of -safety. The secret never reaches a finding, so it cannot escape through JSON, -SARIF or a baseline file. - -### CI - -`--output=sarif` produces SARIF 2.1.0, which GitHub renders inline on the pull -request: - -```yaml -- run: php artisan redactor:scan --output=sarif > redactor.sarif -- uses: github/codeql-action/upload-sarif@v3 - with: - sarif_file: redactor.sarif -``` - -### Suppressing a finding in place - -A fixture, a documented example, a sandbox credential: mark the line and the -scanner skips it, with the reason next to the code rather than in a baseline -file. - -```php -$stripe = 'sk_test_4eC39HqLyjWDarjtT1zdp7dc'; // redactor:allow - Stripe's public test key -``` - -### Ruleset fingerprint - -Every scan reports a short fingerprint of the rules it ran: in JSON, in SARIF -under the tool's properties, and in the baseline it writes. Two runs with the -same fingerprint are comparable; a baseline generated under a different one is -warned about, since what it accepted may no longer mean the same thing. - -### Baselines - -A repository with test fixtures or a documented example key can never go green -without a baseline, so record what you have accepted and let CI fail only on new -findings: - -```bash -php artisan redactor:scan --update-baseline # writes .redactor-baseline.json -php artisan redactor:scan --bail # now fails only on new secrets -``` - -The baseline stores a hash of the rule, the path and the secret. The secret -itself is never written to the file, and a finding stays accepted when the code -around it moves. +| Page | What it covers | +| --- | --- | +| [Getting Started](docs/getting-started.md) | Installation, the Monolog tap, `redact()`, `inspect()`, the fluent builder, profiles and the five that ship. | +| [Configuration](docs/configuration.md) | Every key in `config/redactor.php` with its type, default and environment variable; the shipped profiles compared. | +| [Rules](docs/rules.md) | Pattern rules, validators, keywords, samples, dictionary rules, allow-lists, path rules, safe and blocked keys, known secrets, confidence and how detections are resolved. | +| [Operators and Pseudonymisation](docs/operators-and-pseudonymisation.md) | Every operator with example output, precedence, surrogates, the key and salt, reversible tokens and `detokenize()`. | +| [Boundaries](docs/boundaries.md) | Log channels, HTTP responses, streams, MCP servers, AI agents, exports and jobs, and the `RedactionPerformed` event. | +| [Scanning](docs/scanning.md) | `redactor:scan` in full: paths, output formats, git modes, decoding, baselines, suppression, verification, the hook and workflow, exit codes. | +| [Entity Recognition](docs/entity-recognition.md) | Finding names, places and organisations in prose with a Presidio-compatible recogniser, and when not to. | +| [Testing](docs/testing.md) | `Redactor::fake()` and its assertions, `redactor:validate`, rule samples, the package's own test conventions. | +| [Extending](docs/extending.md) | Every contract, how to register each, a worked custom strategy and operator, and macros. | +| [Upgrading](docs/upgrading.md) | Every renamed class and method from 0.1.0, every behaviour change, and what to do about each. | ## Requirements - PHP 8.3, 8.4 or 8.5 - Laravel 12.x or 13.x -## Installation - -```bash -composer require kirschbaum-development/redactor -php artisan vendor:publish --tag=redactor-config -``` +`laravel/mcp` and `laravel/ai` are suggested, not required; the adapters for them are only loaded when you use them. ## Testing @@ -1350,52 +135,12 @@ composer mutate # mutation testing (Pest); local only, not run in CI composer preflight # everything CI runs ``` -Coverage and mutation testing need a coverage driver (pcov or Xdebug) loaded -in the CLI; without one Pest reports no coverage and generates no mutations. -Both scripts raise the memory limit, which the coverage report needs. - -### In your own test suite - -Redaction is a runtime promise, and a promise nobody tests is one that quietly -stops being kept. `Redactor::fake()` swaps in a redactor that still redacts -but remembers every call, so a test can say the thing that matters: - -```php -use Kirschbaum\Redactor\Facades\Redactor; - -$fake = Redactor::fake(); // before the code under test logs anything - -$this->postJson('/login', ['email' => 'bob@example.com', 'password' => 'hunter2']); - -$fake->assertNeverEmitted('hunter2', 'bob@example.com'); // across every call and profile -$fake->assertRedacted('password'); -$fake->assertFinding('email'); -$fake->assertProfileUsed('strict'); -``` - -`assertNeverEmitted()` checks everything the redactor produced, whichever path -it took - the log tap, a queued export, a response.

The processor redacts the record's message, context and extra, and then the channel's own formatter renders the result, so a channel writing JSON keeps writing JSON. Put the tap on a `stack` channel and every channel in the stack is covered. + +Redaction inside the processor never throws. A profile name typo, an unreadable config value or a strategy that fails on unexpected input all fail closed: the message becomes `[REDACTED] (redaction failed)`, the context and extra become `['redaction' => '...']`, and the record is still written. The package's own diagnostics go through a re-entrancy guard, so a warning raised inside the log pipeline cannot re-enter the handler that triggered it. + +Run `php artisan redactor:validate` at deploy time to find a broken profile before the first log line does. + +### The Formatter + +`RedactorFormatter` is a Monolog formatter that redacts and renders. It owns the output format, so prefer the tap unless a channel specifically wants a self-contained drop-in. It can wrap an inner formatter rather than replace it: + +```php +use Kirschbaum\Redactor\Logging\RedactorFormatter; +use Monolog\Formatter\JsonFormatter; + +$handler->setFormatter(new RedactorFormatter(new JsonFormatter)); +``` + +Without an inner formatter it writes `[datetime] channel.LEVEL: message {context} {extra}`. `formatBatch()` renders every record, so batching handlers lose nothing. + +`RedactorFormatterTap` installs `RedactorFormatter` on every formattable handler of a channel. It discards whatever formatter the handler had, so a channel writing JSON stops writing JSON the moment it is enabled. It is the successor of the 0.1.0 `CustomLogTap` and is kept for channels that relied on it; new channels should use `RedactorTap`. + +### Opaque Objects + +Throwables, `DateTimeInterface`, `DateTimeZone`, enums and closures pass through the walk untouched. A Throwable has no public properties and would encode to `{}`, so `['exception' => $e]` reaching the formatter as `[]` would lose the stack trace; a Carbon instance would be exploded into its `toArray()` components. Every logging formatter already knows how to render them. + +Key rules still apply, since the strategy chain runs before the opacity check: + +```php +Log::error('failed', ['exception' => $e, 'password' => 'x']); +// ['exception' => $e, 'password' => '[REDACTED]'] + +Log::info('state', ['secret' => SomeEnum::Value]); +// ['secret' => '[REDACTED]'] +``` + +Other objects are walked. Anything with a `toArray()` method, a model or a collection, is walked through that; anything else is walked through its JSON encoding. An object that can be neither converted is handled according to `non_redactable_object_behavior`: `preserve` (default), `remove`, `redact` or `empty_array`. + +### Long Strings and Large Objects + +The values most often over `max_value_length` in a Laravel log are stack traces and request bodies, which is exactly what the reader needed, so the default keeps the head, scans it, and notes what was cut: + +``` +Stack trace: #0 /app/Http/... [REDACTED] (String truncated: 65536 characters, 5000 kept) +``` + +Set `large_string_behavior` to `redact` to replace the whole value instead. An array or object with more items than `max_object_size` becomes `['_large_object_redacted' => '[REDACTED] (Array with 250 items)']`. A subtree deeper than `max_depth` becomes `[REDACTED] (Max depth of 32 exceeded)`, and an object already on the recursion stack becomes `[REDACTED] (Circular reference to App\Models\User)`. + +## HTTP Responses + +Data that leaves through an API needs the same boundary as data that leaves through a log. The package registers a `redact` middleware alias that redacts a response before it is sent, with a profile per route: + +```php +Route::get('/export', ExportController::class)->middleware('redact:observability'); +Route::get('/me', MeController::class)->middleware('redact'); +``` + +What happens depends on the response: + +| Response | Treatment | +| --- | --- | +| `JsonResponse` | Redacted as data, so structure and types survive. | +| Any response whose `Content-Type` contains `json` | Decoded, redacted as data, re-encoded. Falls back to text if the body is not valid JSON. | +| `text/*`, `xml`, `javascript`, `x-www-form-urlencoded`, or no content type | Redacted as text. | +| `StreamedResponse` | The callback is wrapped in a `StreamRedactor`. See [Streams](#streams). | +| `BinaryFileResponse`, any other content type, empty body | Passed through. | + +The profile's `_redacted` markers are never written into a response. Where a consumer has typed the field, use `nullify` so the field stays a field and keeps its type: + +```php +'operators' => ['ssn' => 'nullify', 'age' => 'nullify'], +``` + +The middleware fails closed. A response that cannot be redacted becomes a JSON `500` with the body `{"message": "The response could not be redacted."}` and none of the original content. Run `redactor:validate` at deploy time so that never happens in production. + +## Streams + +A streamed response, server-sent events, a model's tokens, a file piped through, is redacted as it streams. The `redact` middleware wraps a `StreamedResponse` callback for you; for anything else, use `StreamRedactor` directly: + +```php +use Kirschbaum\Redactor\Redactor; +use Kirschbaum\Redactor\Streaming\StreamRedactor; + +$stream = new StreamRedactor(app(Redactor::class), 'observability'); + +// An iterable of chunks: a generator, an array, a model's token stream +foreach ($stream->through($llm->tokens()) as $safe) { + echo $safe; +} + +// A callback that echoes, wrapped so what it echoes is redacted +$callback = $stream->wrap(fn () => $this->export($rows)); + +// The same, as a StreamedResponse +return $stream->response(fn () => $this->export($rows), 200, ['Content-Type' => 'text/csv']); +``` + +For full control, feed chunks yourself: + +```php +echo $stream->push($chunk); // returns whatever is now safe to emit, possibly '' +echo $stream->flush(); // once the stream has ended +``` + +Redacting each chunk on its own would miss every secret that straddles a boundary, and buffering the whole stream would defeat the point of streaming. So `StreamRedactor` holds back the most recent bytes until more arrive: + +- The last `holdback` bytes (the third constructor argument, default 1024) are never emitted until more input pushes them out. +- The cut always falls on a line end. No shipped rule except the PEM block matches across a newline, so a line end is always safe. +- When a stream goes a whole hold-back window without a line end, the cut falls on a word boundary instead. With no boundary at all, an unbroken run is emitted once it has outlived a window. +- A PEM block that has opened but not closed is held whole, however many lines it spans. + +The cost is latency in bytes, not time. Raise the hold-back for content whose secrets are longer than a screen line. `wrap()` and `response()` take a `$chunkSize` (default 4096) for the output buffer that feeds the redactor. + +## MCP Servers + +An MCP server hands data straight to a model. With Laravel's MCP package, one trait redacts everything the server returns: + +```php +use Kirschbaum\Redactor\Mcp\RedactsResponses; +use Laravel\Mcp\Server; + +class SupportServer extends Server +{ + use RedactsResponses; + + protected function redactionProfile(): ?string + { + return 'observability'; // null for the default profile + } +} +``` + +The trait sits where the server builds its JSON-RPC responses, so it covers HTTP and stdio alike, and the server's own test helpers exercise it: `SupportServer::tool(LookupCustomer::class)->assertDontSee($email)` tests the redaction along with the tool. + +What is redacted: + +| Part of the response | Treatment | +| --- | --- | +| `result.content[].text` (tool results) | As text. | +| `result.content[].resource.text` (embedded resources) | As text. | +| `result.structuredContent` | As data, without markers. If it cannot be redacted it becomes `['redaction' => 'failed']`. | +| `result.contents[]` (resource reads) | As text. | +| `result.messages[].content` (prompt messages) | As text, whether a string or a content block. | +| `error.message` | As text. | +| `params.content` of a streamed notification | As tool output. | + +What is not: the JSON-RPC envelope, ids, protocol fields, and any binary content such as an image's `data` or a `blob`, so the protocol stays valid and an image is not mistaken for a high-entropy secret. + +Use a profile whose operators tokenise when the model needs to refer to a value the application will act on. See [Reversible Tokens](operators-and-pseudonymisation.md#reversible-tokens). `laravel/mcp` is a suggested dependency, not a required one. + +## AI Agents + +With Laravel's AI package, the `RedactPrompt` middleware redacts a prompt before the provider sees it and resolves tokens in the answer on the way back: + +```php +use Kirschbaum\Redactor\Ai\RedactPrompt; +use Laravel\Ai\Contracts\Agent; +use Laravel\Ai\Contracts\HasMiddleware; +use Laravel\Ai\Promptable; + +class SupportAgent implements Agent, HasMiddleware +{ + use Promptable; + + public function instructions(): string + { + return 'You answer support tickets.'; + } + + public function middleware(): array + { + return [RedactPrompt::using('ai')]; + } +} +``` + +`RedactPrompt::using(?string $profile, bool $detokenizeResponse = true)` takes the profile and whether to resolve tokens in the response text. With a profile whose operators tokenise, the model reasons about `tok_email_k4m9rp2xzq` and the application receives the real address back in the response. With a profile that redacts outright, the model never sees the value. Pass `detokenizeResponse: false` to keep tokens in the answer, for instance when the answer is going to be logged or shown rather than acted on. + +The round trip is: + +1. The prompt text is passed through `redactSafely()` with the profile. +2. The revised prompt goes to the provider. +3. When the response arrives, `Redactor::detokenize()` replaces every known token in its text. + +`laravel/ai` is a suggested dependency, not a required one. + +## Exports, Jobs and Everything Else + +The same call covers everything else an application emits.

The detection's offset is then a byte offset like every other finding's. + +## The Circuit Breaker + +A sidecar that is down fails every call at the full timeout, so inside a log tap every line would wait seconds to be told nothing. A recogniser that throws is skipped and the output is rules-only for that value. After `failure_threshold` consecutive failures the breaker opens for `cooldown` seconds and the recogniser is not asked again until it closes; one success closes it. + +Breaker state is per process and keyed by recogniser and profile. It is deliberately not shared through the cache, because a breaker that needed the cache to work would fail exactly when the cache does. Each failure and each unknown driver is logged through the package's re-entrancy guard, so the warning cannot loop back into the log tap that raised it. + +## Writing a Recognizer + +To plug in something that does not speak the Presidio contract, implement `Kirschbaum\Redactor\Recognition\Recognizer`: + +```php +use Kirschbaum\Redactor\Recognition\RecognizedSpan; +use Kirschbaum\Redactor\Recognition\Recognizer; + +class OnnxRecognizer implements Recognizer +{ + public function name(): string + { + return 'onnx'; + } + + /** + * @param array $entities the recogniser's own labels; empty means all + * @return array + */ + public function recognize(string $text, string $language, array $entities, float $scoreThreshold): array + { + $spans = []; + + foreach ($this->model->predict($text) as $prediction) { + $spans[] = new RecognizedSpan( + entity: $prediction->label, // 'PERSON' + start: $prediction->start, // character offset + end: $prediction->end, // character offset, exclusive + score: $prediction->score, // 0.0 to 1.0 + ); + } + + return $spans; + } +} +``` + +Register it, usually in a service provider's `boot()`, and select it by name: + +```php +Redactor::registerRecognizer(new OnnxRecognizer); +``` + +```php +'recognition' => ['enabled' => true, 'driver' => 'onnx', /* ... */], +``` + +A recogniser reports; it never rewrites. It may throw when it cannot answer, and the strategy turns that into "rules only, this time" and counts it against the breaker. Return character offsets, not bytes. + +## When to Use It + +Use it on profiles that run from queues, exports and scans, where a model call's milliseconds are lost in the job's seconds and the payload is prose: support transcripts, free-text notes, exported records. Pair it with `surrogate` for people so an exported conversation stays readable and consistent. + +Do not enable it on the request path or on a busy log channel. The rule engine costs microseconds per value; a recogniser costs milliseconds and a network round trip, per prose-shaped value, on every log line that carries one. The gates keep JSON and stack traces out, but a `message` field is prose by definition. + +Do not rely on it for credentials. A model finds names; a pattern finds keys. The rules run either way. + +Still open in the package: an in-process ONNX recogniser so recognition needs no sidecar, and batching every candidate string in a payload into one recogniser call. diff --git a/docs/extending.md b/docs/extending.md new file mode 100644 index 0000000..6992460 --- /dev/null +++ b/docs/extending.md @@ -0,0 +1,440 @@ +# Extending + +- [Introduction](#introduction) +- [Contracts at a Glance](#contracts-at-a-glance) +- [Strategies](#strategies) + - [The Strategy Contract](#the-strategy-contract) + - [The Marker Interfaces](#the-marker-interfaces) + - [A Worked Custom Strategy](#a-worked-custom-strategy) + - [Registering a Strategy](#registering-a-strategy) + - [What a Strategy Can Reach](#what-a-strategy-can-reach) +- [Detectors](#detectors) +- [Operators](#operators) + - [A Worked Custom Operator](#a-worked-custom-operator) +- [Surrogate Generators](#surrogate-generators) +- [Recognizers](#recognizers) +- [Verifiers](#verifiers) +- [Token Stores](#token-stores) +- [Macros](#macros) + +## Introduction + +The package has one seam for each thing it does: a strategy for a step in the chain, a detector for finding spans, an operator for replacing them, a generator for shaping a surrogate, a recogniser for asking a model, a verifier for asking a provider, and a token store for keeping originals.

When it returns true, `handle()` returns what should stand in the value's place. By default the chain stops there and the walk does not descend, so a strategy that returns a container has ended the matter for everything inside it. + +### The Marker Interfaces + +Four empty interfaces in the same namespace change how the chain treats a strategy: + +| Marker | Effect | +| --- | --- | +| `ChainableStrategy` | `handle()` rewrote part of the value rather than replacing it, so the strategies after it still run on what it returned. `LargeStringStrategy` is one. | +| `DetectingStrategy` | Extends `ChainableStrategy`. `handle()` returns the value untouched and reports what it found through `$context->collect()`. Every detecting strategy sees the same original string, and the context rewrites it once after the last of them. `RegexPatternsStrategy`, `ShannonEntropyStrategy`, `KnownSecretsStrategy` and `EntityRecognitionStrategy` are these. | +| `PreservingStrategy` | `handle()` declares the value safe. The chain ends, the walk does not descend, and any pending detections are discarded. `SafeKeysStrategy` is one. | +| `ConditionalStrategy` | Adds `appliesTo(RedactorConfig $config): bool`. A strategy returning false is left out of the chain for that profile, so it costs nothing. `EntityRecognitionStrategy` uses it to stay inert until enabled. | + +Implement the markers that describe what your `handle()` does.

Classes are instantiated without arguments from config, so a strategy that needs dependencies is registered at runtime. Custom strategies are cloned into each chain. + +A profile may also list a fully qualified class name directly, without registering it, as the shipped profiles do. + +### What a Strategy Can Reach + +`RedactionContext` is what a strategy is handed. The parts meant for strategies: + +| Member | Use | +| --- | --- | +| `$context->config` | The resolved `RedactorConfig`: `replacement`, `patterns`, `minConfidence`, `shannonEntropy`, `recognition` and so on. | +| `$context->operate(Detection $detection, ?OperatorSpec $atLocation = null)` | Apply the configured operator to a detection and return the replacement text. | +| `$context->operatorSpecFor(Detection $detection)` | Which operator would apply, without applying it. | +| `$context->collect(Detection $detection)` | Hold a detection for resolution, from a `DetectingStrategy`. | +| `$context->isAllowed(string $value)` | Whether the profile allow-list excuses the value. | +| `$context->recordRedaction(string $key, ?string $rule, int $offset, int $length, string $matched, ?string $entity, ?Confidence $confidence, bool $redacted)` | Record that something was redacted under a key and report a finding. | +| `$context->recordDetection(Detection $detection, bool $redacted = true)` | The same, from a detection. | +| `$context->markRedacted()` | Set the redaction flag alone. | +| `$context->secrets()` | The known secrets in play, profile and runtime. | +| `$context->pseudonymizer()` | The profile's pseudonymizer, or null. | +| `$context->recognizers()` | The recogniser registry. | +| `$context->getCachedEntropy()`, `cacheEntropy()` | The per-redaction entropy cache. | + +## Detectors + +`Detection\Detector` is the contract for anything that can find sensitive spans in a string: + +```php +namespace Kirschbaum\Redactor\Detection; + +use Kirschbaum\Redactor\RedactionContext; + +interface Detector +{ + /** @return array offsets relative to $subject as given */ + public function detect(string $subject, string $key, RedactionContext $context): array; +} +``` + +A detector reads; it never writes. It reports every span it believes is sensitive with an entity, a rule name, a byte offset into the subject exactly as received, the matched text and a `Confidence`, and leaves the decisions to the context. The shipped detecting strategies implement both `Strategy` and `Detector`, with `handle()` collecting whatever `detect()` returns: + +```php +class MyDetector implements DetectingStrategy, Detector, Strategy +{ + public function shouldHandle(mixed $value, string $key, RedactionContext $context): bool + { + return is_string($value); + } + + public function handle(mixed $value, string $key, RedactionContext $context): mixed + { + foreach ($this->detect($value, $key, $context) as $detection) { + $context->collect($detection); + } + + return $value; + } + + public function detect(string $subject, string $key, RedactionContext $context): array + { + // ... + } +} +``` + +Build a `Confidence` with `Confidence::of($score, $reason)` and add signals with `->with($name, $delta, $reason)`. `KeywordContext::boost($confidence, $subject, $offset, $key)` adds the shared context signal. Where the detector fails and the value cannot be trusted, return `[Detection::failClosed($entity, $rule, $subject, $key, $reason)]`, which replaces the whole value whatever the operator policy says. + +## Operators + +An operator produces the text that replaces a detected span: + +```php +namespace Kirschbaum\Redactor\Operators; + +use Kirschbaum\Redactor\Detection\Detection; + +interface Operator +{ + public function apply(Detection $detection, OperatorContext $context): string; +} +``` + +Whether anything changed is decided by comparing the returned text with the detected value: an operator that returns `$detection->value` unchanged, as `preserve` does, has its finding reported without the payload being marked redacted. `OperatorContext` is deliberately narrow: an operator receives the profile's `replacement`, its own `options` and a lazily resolved pseudonymizer, and nothing else. It cannot reach the payload, the profile or the container, which keeps it testable in isolation and impossible to turn into a second detection layer. + +### A Worked Custom Operator + +An operator that replaces a value with its category, so a log says `` rather than `[REDACTED]`: + +```php +namespace App\Redaction; + +use Kirschbaum\Redactor\Detection\Detection; +use Kirschbaum\Redactor\Operators\Operator; +use Kirschbaum\Redactor\Operators\OperatorContext; + +class ClassifyOperator implements Operator +{ + public function apply(Detection $detection, OperatorContext $context): string + { + $open = $context->stringOption('open', '<'); + $close = $context->stringOption('close', '>'); + + return $open.$detection->entity.$close; + } +} +``` + +Register it, in a service provider's `boot()`, and use it from config by name: + +```php +Redactor::registerOperator('classify', new ClassifyOperator); +``` + +```php +'operators' => [ + 'default' => 'classify', + 'phone' => ['classify' => ['open' => '[', 'close' => ']']], +], +``` + +`OperatorContext` exposes the profile's `replacement` and the raw `options` array as public properties, offers `intOption()`, `boolOption()` and `stringOption()`, each returning the default when the option is absent or the wrong type, and `pseudonymizer()` for an operator that needs a stable mapping. An operator that pseudonymises should return `$context->replacement` when `pseudonymizer()` is null, as the shipped ones do, rather than emit an unkeyed stand-in. + +Registering a name that already exists replaces the built-in operator, so an application can, for example, swap `tokenize` for one backed by a vault. + +## Surrogate Generators + +The `surrogate` operator asks a `SurrogateFactory` for the first generator that supports the value. Add one for a domain type the package has never heard of, a policy number, an NHS number, an internal account format: + +```php +namespace App\Redaction; + +use Kirschbaum\Redactor\Operators\Surrogates\SurrogateGenerator; +use Kirschbaum\Redactor\Support\DeterministicRandom; + +class PolicyNumberSurrogate implements SurrogateGenerator +{ + public function supports(string $entity, string $value): bool + { + return $entity === 'policy_number'; + } + + public function generate(string $value, DeterministicRandom $random, array $options = []): string + { + return 'POL-'.$random->token(8, 'ABCDEFGHJKLMNPQRSTUVWXYZ23456789'); + } +} +``` + +`DeterministicRandom` is a keyed, reproducible stream seeded from the value, so the same input yields the same surrogate on any machine. It offers `byte()`, `below($bound)`, `pick($alphabet)`, `digit()` and `token($length, $alphabet)`. + +Generators are registered ahead of the built-in ones on the factory, and the factory is given to the `SurrogateOperator`, which is registered under `surrogate`: + +```php +use Kirschbaum\Redactor\Operators\SurrogateOperator; +use Kirschbaum\Redactor\Operators\Surrogates\SurrogateFactory; + +$factory = new SurrogateFactory([new PolicyNumberSurrogate]); + +Redactor::registerOperator('surrogate', new SurrogateOperator($factory)); +``` + +`CharacterClassSurrogate` supports everything and stays last, so a generator that claims a value wins over it. + +## Recognizers + +Implement `Recognition\Recognizer` and register it with `Redactor::registerRecognizer()`. [Entity Recognition](entity-recognition.md#writing-a-recognizer) has the full contract and a worked example. + +## Verifiers + +A verifier asks one provider whether one credential is live: + +```php +namespace Kirschbaum\Redactor\Verification; + +interface Verifier +{ + public function name(): string; + + public function host(): string; + + public function supports(string $entity, string $rule): bool; + + public function verify(string $secret): VerificationResult; +} +``` + +`name()` is what goes in `scan.verification.verifiers`. `host()` is announced before any request is sent. `verify()` must never throw or log the secret, and returns `VerificationResult::active()`, `::inactive()` or `::unknown()`, each with an optional note: + +```php +namespace App\Redaction; + +use Illuminate\Support\Facades\Http; +use Kirschbaum\Redactor\Verification\VerificationResult; +use Kirschbaum\Redactor\Verification\Verifier; +use Throwable; + +class TwilioKeyVerifier implements Verifier +{ + public function name(): string { return 'twilio_key'; } + + public function host(): string { return 'api.twilio.com'; } + + public function supports(string $entity, string $rule): bool + { + return $entity === 'twilio_key'; + } + + public function verify(string $secret): VerificationResult + { + try { + $response = Http::withToken($secret)->timeout(5)->get('https://api.twilio.com/2010-04-01/Accounts.json'); + + return match (true) { + $response->status() === 401 => VerificationResult::inactive('Twilio rejected the key (401).'), + $response->successful() => VerificationResult::active('Twilio accepted the key; rotate it.'), + default => VerificationResult::unknown(sprintf('Twilio returned %d.', $response->status())), + }; + } catch (Throwable $e) { + return VerificationResult::unknown('Could not reach Twilio: '.$e->getMessage()); + } + } +} +``` + +The shipped verifiers are hard-wired into `SecretVerifier`; there is no registry for verifiers yet. To use your own, construct a `SecretVerifier` with the full list and give it to the scanner: + +```php +use Kirschbaum\Redactor\Scanner\Scanner; +use Kirschbaum\Redactor\Verification\SecretVerifier; + +$verifier = new SecretVerifier( + allowed: ['twilio_key', 'github_token'], + verifiers: [new TwilioKeyVerifier, new GitHubTokenVerifier], +); + +$result = app(Scanner::class)->withVerifier($verifier)->scanFile($path, 'file_scan'); +``` + +`SecretVerifier::fromConfig($settings, $verifiers)` applies the same three-gate rule to a custom list. + +## Token Stores + +`Tokenization\TokenStore` is where a token's original lives while the token is out in the world: + +```php +namespace Kirschbaum\Redactor\Tokenization; + +interface TokenStore +{ + public function put(string $token, string $value, string $entity, ?int $ttlSeconds = null): void; + + public function get(string $token): ?string; + + public function forget(string $token): void; +} +``` + +`get()` returns null for a token it does not know, and the detokenizer leaves such tokens alone. The shipped `CacheTokenStore` encrypts each value with the application's encrypter before writing it to the cache. + +To use another store, bind it in a service provider's `register()`. The package resolves the store lazily the first time a `tokenize` operator runs, so the binding is picked up as long as it exists before then: + +```php +use Kirschbaum\Redactor\Tokenization\TokenStore; + +$this->app->singleton(TokenStore::class, fn () => new VaultTokenStore($this->app->make(Vault::class))); +``` + +## Macros + +Both `Kirschbaum\Redactor\Redactor` and `Kirschbaum\Redactor\PendingRedaction` are `Macroable`, so an application can add its own methods to the facade and to the fluent builder: + +```php +use Kirschbaum\Redactor\PendingRedaction; +use Kirschbaum\Redactor\Redactor; + +Redactor::macro('forExport', fn (mixed $content) => $this->profile('observability')->withoutMarkers()->redact($content)); + +PendingRedaction::macro('strictly', fn () => $this->profile('strict')); +``` + +```php +Redactor::forExport($rows); +Redactor::profile(null)->strictly()->redact($data); +``` + +Both are also `Conditionable`, so `when()` and `unless()` are available on the redactor and on a pending redaction. diff --git a/docs/getting-started.md b/docs/getting-started.md new file mode 100644 index 0000000..f31dc06 --- /dev/null +++ b/docs/getting-started.md @@ -0,0 +1,239 @@ +# Getting Started + +- [Introduction](#introduction) +- [Installation](#installation) +- [Redacting Logs](#redacting-logs) +- [Your First Redaction](#your-first-redaction) +- [Inspecting a Redaction](#inspecting-a-redaction) +- [The Fluent Builder](#the-fluent-builder) +- [Profiles](#profiles) + - [The Shipped Profiles](#the-shipped-profiles) + - [Strategies](#strategies) +- [Exceptions](#exceptions) +- [Validating Your Configuration](#validating-your-configuration) +- [Next Steps](#next-steps) + +## Introduction + +Redactor takes a value, a string, an array, an object, and returns a copy with the sensitive parts replaced.

If a profile is misconfigured or a strategy fails on unexpected input, the record's content is replaced rather than emitted and logging carries on.

The text around it survives: + +```php +Redactor::redact('User bob@example.com placed order 123'); + +// 'User [REDACTED] placed order 123' +``` + +Pass a profile name as the second argument to use something other than the default profile: + +```php +Redactor::redact($data, 'strict'); +``` + +Objects are handled too. A Laravel model or anything with a `toArray()` method is walked through that; other objects are walked through their JSON form. Throwables, `DateTimeInterface`, `DateTimeZone`, enums and closures pass through untouched, since taking them apart would destroy them, though key rules still apply to the key they sit under. + +## Inspecting a Redaction + +When you need to know whether anything matched, call `inspect()` instead of reading the `_redacted` marker back out of the payload: + +```php +$result = Redactor::inspect($data); + +$result->value; // the redacted payload +$result->wasRedacted; // bool +$result->redactedKeys; // ['password', 'api_key', 'email'] +$result->findings; // an array of MatchFinding +``` + +Each `MatchFinding` carries the rule that fired, the entity it found, the key, a byte offset and length into the value you passed, and a confidence score with the signals behind it: + +```php +foreach ($result->findings as $finding) { + $finding->rule; // 'email' + $finding->entity(); // 'email' + $finding->key; // 'email' + $finding->offset; // 0 + $finding->length; // 16 + $finding->confidence; // a Confidence, or null for a blocked key +} +``` + +`RedactionResult` and `MatchFinding` are both `Arrayable` and `JsonSerializable`. The array form of a finding omits the matched text, so a result can be logged without becoming the leak it reports. + +`inspect()` also takes a third argument, `$mark`, which overrides the profile's `mark_redacted` setting for one call: + +```php +Redactor::inspect($data, 'default', mark: false)->value; +``` + +## The Fluent Builder + +`Redactor::profile()` returns a `PendingRedaction` you can configure before running it: + +```php +Redactor::profile('strict')->redact($data); + +Redactor::profile('observability')->withoutMarkers()->inspect($data); + +Redactor::profile('audit') + ->when($verbose, fn ($redaction) => $redaction->withMarkers()) + ->redact($data); +``` + +The builder offers: + +| Method | Effect | +| --- | --- | +| `profile(?string $profile)` | Use the given profile, or `null` for the default. | +| `withMarkers()` | Write the `_redacted` markers into the payload, whatever the profile says. | +| `withoutMarkers()` | Never write the markers. | +| `redact(mixed $content)` | Redact and return the value. | +| `inspect(mixed $content)` | Redact and return a `RedactionResult`. | +| `redactSafely(mixed $content)` | Redact without ever throwing. | + +Both the redactor and the pending redaction are `Conditionable` and `Macroable`, so `when()` and `unless()` work as they do elsewhere in Laravel, and you can add your own methods. See [Extending](extending.md#macros). + +## Profiles + +A profile is one complete redaction configuration: which strategies run and in what order, which keys are safe or blocked, which patterns to look for, and what to do with what is found. Profiles live under `profiles` in `config/redactor.php`, and every entry point accepts a profile name. + +Profiles exist because the right amount of redaction depends on where the data is going. An audit log wants everything gone; an application log wants values pseudonymised so you can still count users; a file scan wants content rules only, since there are no keys to match. + +You can list and check profiles at runtime: + +```php +Redactor::profiles(); // ['default', 'strict', 'file_scan', 'observability', 'performance'] +Redactor::hasProfile('audit'); // false +Redactor::strategies('strict'); // the resolved strategy chain +``` + +### The Shipped Profiles + +| Profile | Intended for | What makes it different | +| --- | --- | --- | +| `default` | Application logs and general use | Every strategy, the shared credential and identity rules, entity recognition present but inert, cards partially masked. | +| `strict` | Audit trails and sensitive contexts | More blocked keys (`phone`, `address`, `ip`, `name`, `username`), IPv4 and UUID patterns, entropy threshold 4.0 over 15 characters, `max_value_length` 1000, non-redactable objects redacted. | +| `observability` | Logs you still need to reason about | Pseudonymises emails, phones, IPs and cards with stable surrogates instead of redacting them; `min_confidence` 0.4; no markers. | +| `file_scan` | `redactor:scan` | No key strategies at all; adds labelled rules such as `api_key_generic`, `aws_secret_key`, `base64_key` and `password_assignment`. | +| `performance` | High-throughput paths | Key rules, known secrets and two patterns (`email`, `simple_token`); no size limits, no entropy, no markers. | + +The `default`, `strict`, `observability` and `file_scan` profiles share the same credential and identity rules. They are defined once at the top of the config file and spread into each profile, so a credential one profile catches is caught by the others. [Configuration](configuration.md#the-shipped-profiles-compared) compares every setting side by side. + +### Strategies + +A profile lists its strategies in the order they run. The shipped ones are: + +| Strategy | Role | +| --- | --- | +| `SafeKeysStrategy` | Preserves values under safe keys, subtree included, and stops the walk. | +| `BlockedKeysStrategy` | Redacts values under blocked keys. | +| `LargeObjectStrategy` | Replaces arrays and objects with more items than `max_object_size`. | +| `LargeStringStrategy` | Truncates strings over `max_value_length`, keeping and scanning the head. | +| `KnownSecretsStrategy` | Finds the application's own credentials wherever they appear verbatim. | +| `RegexPatternsStrategy` | Finds spans by pattern. | +| `ShannonEntropyStrategy` | Finds tokens random enough to be a credential. | +| `EntityRecognitionStrategy` | Asks a named entity recogniser about free text. Inert until `recognition.enabled` is true. | + +The chain stops at the first strategy that replaces a value outright. The last four are *detectors*: they report what they found and where, change nothing, and once every detector has seen the value the context resolves the reports and rewrites the string once. [Rules](rules.md#how-detections-are-resolved) explains what follows from that. + +## Exceptions + +Everything the package throws implements `Kirschbaum\Redactor\Exceptions\RedactorException`, so one `catch` covers all of it: + +| Exception | Extends | Thrown when | +| --- | --- | --- | +| `ConfigurationException` | `InvalidArgumentException` | A profile or rule is misconfigured.

That is the method the log processor, the middleware and the stream redactor use, since a throw inside the pipeline that reports errors would take the error with it. + +## Validating Your Configuration + +A broken profile throws the first time something uses it, which in the log path means it is replaced rather than emitted.

An operator answers "so what". They are separate because the right answer differs by context for the very same value: an email in an audit log wants a stable surrogate so the log stays joinable, the same email in a support export wants deleting, and in a secret scan it wants reporting and nothing else. + +Operators are chosen per *entity*, the kind of thing that was found, rather than per rule. Every detector goes through the same policy: a value found by its key uses the lowercased key name as its entity, a high-entropy token has the entity `high_entropy`, a known secret has `known_secret`, a pattern match has whatever its rule's `entity` says. + +## Configuring Operators + +A profile's `operators` block maps entities to operators, with `default` for everything else: + +```php +'operators' => [ + 'default' => 'redact', + 'email' => ['surrogate' => ['preserve_domain' => true]], + 'credit_card' => ['partial' => ['keep' => 4]], + 'ssn' => 'nullify', +], +``` + +An operator is written in any of three spellings, depending on how much you are saying: + +```php +'redact' // just the name +['partial' => ['keep' => 4]] // the name mapped to its options +['operator' => 'partial', 'keep' => 4] // the name as a key beside its options +``` + +The same spellings work in a pattern rule's `operator` option and as the value of a path rule. An operator name that is not registered is not caught when the profile is built: at redaction time the value is redacted with the replacement string and a warning names the operator, the profile and the rule. + +## The Operators + +| Operator | `alice@customer.com` becomes | Options | +| --- | --- | --- | +| `redact` | `[REDACTED]` | none; writes the profile's `replacement` | +| `mask` | `******************`, length preserved | `mask_character` (default `*`) | +| `partial` | `**************.com`, last N kept | `keep` (default 4), `mask_character` | +| `remove` | deleted | none | +| `nullify` | `null` in a field; deleted inside a string | none | +| `hash` | `[email:k4m9rp2xzq]` | `length` (4 to 64, default 10), `labelled` (default true) | +| `surrogate` | `u_7f3ac9@customer.com` | depends on the generator, see [Surrogates](#surrogates) | +| `tokenize` | `tok_email_k4m9rp2xzq` | `ttl` in seconds | +| `preserve` | `alice@customer.com`, reported and unchanged | none | + +A few of them deserve a note: + +**`nullify`** exists for typed fields. `[REDACTED]` in an integer field breaks every consumer that typed it, and `remove` breaks the ones that require the key. Null keeps both honest: the field is there, it has no value. Where a consumer has typed the field, an API contract or MCP structured content, use `nullify`. Inside a string there is no null to write, so a span found by a pattern is deleted as `remove` would. + +**`hash`** produces a stable keyed token that is obviously not real data, for places where a format-preserving surrogate might be mistaken for the genuine value. With `labelled` false it is the bare token. + +**`preserve`** is not a no-op. It lets a scan profile detect and report without rewriting anything, and lets one path rule carve an exception out of a broader one. A preserved finding appears in `inspect()` without marking the payload redacted. + +`hash`, `surrogate` and `tokenize` need a pseudonymisation key. Without one they fall back to `redact` rather than emit an unkeyed stand-in that would look joinable and silently not be. + +Register your own with `Redactor::registerOperator('classify', $operator)` and use it from config by name. See [Extending](extending.md#operators). + +## Precedence + +When a detection has more than one candidate operator, the most specific wins: + +1. The **path** it was found at, when a path rule matched. +2. The **entity** it is: `operators.`. +3. The **rule** that found it, when the rule explicitly set `operator` or a non-default `mode`. +4. The profile **default**: `operators.default`, or `redact` when that is absent. + +Entity beats rule deliberately. "Every email here becomes a surrogate" is a policy decision about data, and which regex spotted it is an implementation detail. Rule beats default only when the rule actually chose something: a rule's `mode` defaults to `replace`, and treating that default as a choice would make `operators.default` unreachable for anything found by a pattern. + +## Pseudonymisation + +Replacing every value with `[REDACTED]` collapses distinct values into one, which destroys the questions logs exist to answer: how many users hit this, is it always the same account, did this session span both services. + +`surrogate`, `hash` and `tokenize` replace a value with a *stable* stand-in instead. The same input always produces the same output, so counts, joins and traces survive: + +```php +Redactor::redact('login by alice@customer.com', 'observability'); +// 'login by u_7f3ac9@customer.com' + +Redactor::redact('logout for alice@customer.com', 'observability'); +// 'logout for u_7f3ac9@customer.com' same surrogate, still joinable +``` + +Inputs are normalised before they are keyed, so `Bob@Example.COM ` and `bob@example.com` produce the same surrogate rather than double-counting one user. + +### Surrogates + +A surrogate preserves the shape of the value it replaces, so anything downstream that parses the value keeps parsing it. The `surrogate` operator picks the first generator that supports the value: + +| Generator | Supports | Example | Options | +| --- | --- | --- | --- | +| `EmailSurrogate` | entity `email`, or a value with exactly one `@` | `alice@customer.com` to `u_7f3ac9@customer.com` | `preserve_domain` (default true). When false the domain becomes `example.invalid`, which can never resolve. | +| `CreditCardSurrogate` | entity `credit_card`, or 12 to 19 digits | `4111 1111 1111 1111` to `4111 1193 7420 8846`, Luhn-valid, spacing kept | `preserve_bin` (default 6). Digits of the issuer prefix to keep. | +| `CharacterClassSurrogate` | everything | `sk_live_4eC39HqLyj` to `sk_live_9mB71TzKnQ`; `+1 (555) 867-5309` to `+7 (204) 331-8874` | `preserve_prefix` (default 0). Leading bytes to keep verbatim. | + +`CharacterClassSurrogate` replaces each letter and digit with another of the same class and leaves separators, punctuation and multibyte characters alone. Length, capitalisation and digit positions survive; nothing of the original does except its shape. It is the fallback for every entity nobody wrote a generator for. To add one, see [Extending](extending.md#surrogate-generators). + +Keeping an email's domain preserves the analysis people run on logs: which tenant, which provider, how many distinct users at one company. Keeping a card's BIN preserves the issuer and card type, which fraud and finance teams aggregate on and which is not specific to a cardholder. + +### The Key and the Salt + +The mapping is one-way: an HMAC, not encryption. There is no route from a surrogate back to the original, but anyone holding the key can confirm a guess, so **the key must not travel with the logs**. + +```php +'pseudonymization' => [ + 'enabled' => env('REDACTOR_PSEUDONYMIZATION', true), + 'key' => env('REDACTOR_PSEUDONYMIZATION_KEY'), + 'salt' => env('REDACTOR_PSEUDONYMIZATION_SALT'), +], +``` + +Leave `key` null to derive one from `APP_KEY`. The derivation is an HMAC over a fixed label, so `APP_KEY` itself is never used directly and a leaked surrogate corpus cannot be turned against anything else signed with it. An explicit key must be at least 16 bytes; a shorter one throws a `PseudonymizationKeyException`, which the operators catch and log before falling back to plain redaction. + +Rotating the key changes every surrogate. That is the intended way to break correlation with logs already exported, and the reason not to rotate it casually. + +Without a usable key, because pseudonymisation is disabled, `APP_KEY` is empty, or the key is too short, `surrogate`, `hash` and `tokenize` fall back to plain redaction and a warning is logged once per redaction. + +### Cross-Profile Stability + +The salt is shared by every profile, so the same user gets the same surrogate on every channel and an audit log on `strict` can be joined with an application log on `observability`. The entity is part of the seed, so the same string found as an `email` and as a `phone` gets different surrogates. + +A profile that must not be linkable back sets its own salt: + +```php +'export' => [ + 'pseudonymization' => ['salt' => 'export-2026'], + // ... +], +``` + +A profile can also set `'pseudonymization' => ['enabled' => false]` to fall back to plain redaction for that profile alone. + +## Reversible Tokens + +A surrogate is one-way. A token is a surrogate the *application* can exchange back, which is what the boundary in front of a language model needs: the model sees `tok_email_k4m9rp2xzq`, refers to it in its answer, and the application resolves it before acting. + +```php +'operators' => [ + 'email' => 'tokenize', + 'credit_card' => ['tokenize' => ['ttl' => 600]], +], +``` + +```php +$prompt = Redactor::redact($ticket, 'ai'); // 'reply to tok_email_k4m9rp2xzq about ...' +$answer = $llm->complete($prompt); // the model reasons about the token +$action = Redactor::detokenize($answer); // 'reply to alice@customer.com about ...' +``` + +A token is `tok__`: the entity lowercased with anything that is not a letter or digit collapsed to `_`, then a 12-character id derived with the pseudonymisation key. It is spelt to survive a model: one word, no punctuation a tokenizer would split on, an entity name a model can reason about. Tokens are stable, so the same address yields the same token in every prompt, and they cannot be guessed. + +The original goes into the token store, encrypted with the application key, for `ttl` seconds. The operator's `ttl` option overrides the global `tokenization.ttl`; a `ttl` of null keeps the original forever. + +### Detokenizing + +`Redactor::detokenize()` walks a string or an array and replaces every token the store knows: + +```php +Redactor::detokenize('reply to tok_email_k4m9rp2xzq'); // 'reply to alice@customer.com' +Redactor::detokenize(['text' => 'tok_email_k4m9rp2xzq', 'n' => 1]); +``` + +A token the store does not know, whether expired, from another application, or invented by the model, is left exactly as it is, since guessing would be worse. Content that is neither a string nor an array is returned unchanged. + +### The Token Store + +Originals live in the application cache under the `redactor:token:` prefix, encrypted with `APP_KEY` before they are written: + +```php +'tokenization' => [ + 'store' => env('REDACTOR_TOKEN_STORE'), // null for the default cache store + 'ttl' => env('REDACTOR_TOKEN_TTL', 86_400), +], +``` + +A cache entry that fails to decrypt, after a key rotation or corruption, is treated as unknown. The store is resolved lazily the first time a `tokenize` operator runs, so the redactor can be built before the cache and encrypter are ready. + +`Kirschbaum\Redactor\Tokenization\TokenStore` is the contract for another backing store, a vault or a table. Bind your implementation to that interface in the container. See [Extending](extending.md#token-stores). + +## Trust Model + +Three things hold the mapping between a stand-in and its original, and they carry different trust: + +| Stand-in | Reversible by | Needs | +| --- | --- | --- | +| `hash`, `surrogate` | nobody | the key, to confirm a guess | +| `tokenize` | the application | the token store and `APP_KEY` | +| `redact`, `mask`, `partial`, `remove`, `nullify` | nobody | nothing | + +Anyone holding the cache and the application key can resolve tokens, which is the trust the application itself already carries. Anyone holding the pseudonymisation key can confirm whether a given email produced a given surrogate, which is why the key stays with the application and never with the logs. Tokens and surrogates are derived with the same key, so rotating it invalidates both. diff --git a/docs/rules.md b/docs/rules.md new file mode 100644 index 0000000..6b5e242 --- /dev/null +++ b/docs/rules.md @@ -0,0 +1,381 @@ +# Rules + +- [Introduction](#introduction) +- [Pattern Rules](#pattern-rules) + - [Shorthand and Full Form](#shorthand-and-full-form) + - [Modes](#modes) + - [Capture Groups](#capture-groups) + - [Validators](#validators) + - [Keywords](#keywords) + - [Minimum Length](#minimum-length) + - [Samples](#samples) + - [Dictionary Rules](#dictionary-rules) + - [Per-Rule Allow Lists](#per-rule-allow-lists) + - [Entity and Operator](#entity-and-operator) +- [Allow-Lists](#allow-lists) +- [Path Rules](#path-rules) +- [Safe and Blocked Keys](#safe-and-blocked-keys) + - [Wildcards](#wildcards) +- [Known Secrets](#known-secrets) +- [Confidence](#confidence) +- [How Detections Are Resolved](#how-detections-are-resolved) +- [PCRE Failures](#pcre-failures) + +## Introduction + +A rule is anything that tells the redactor a value is sensitive.

See [Validators](#validators). | +| `entity` | `string` | the rule name | What kind of thing the rule finds, for `operators`. | +| `confidence` | `float` | `0.6` | The base score of a bare match. See [Confidence](#confidence). | +| `operator` | `string\|array` | none | An operator the rule chooses for itself. See [Entity and Operator](#entity-and-operator). | +| `keywords` | `string[]` | `[]` | Literals at least one of which must appear in the value. See [Keywords](#keywords). | +| `min_length` | `int` | `1` | The shortest text the pattern can match, in bytes. See [Minimum Length](#minimum-length). | +| `samples` | `string[]` | `[]` | Texts the rule must detect. See [Samples](#samples). | +| `counter_samples` | `string[]` | `[]` | Texts the rule must not detect. | +| `allow` | `string[]` | `[]` | Matches this rule alone should let through. See [Per-Rule Allow Lists](#per-rule-allow-lists). | + +A pattern that does not compile is silently dropped from the profile rather than throwing; `redactor:validate` will then report the rule's samples as undetected, if it has any. A rule with no `pattern` and no `words`, or an unrecognised `mode` or `validator`, is a configuration error and throws. + +### Modes + +`mode` says how the matched span is rewritten: + +| Mode | Result for `4111111111111111` | +| --- | --- | +| `replace` (default) | `[REDACTED]` | +| `mask` | `****************`, length preserved | +| `partial` | `************1111`, the last `keep` characters kept | +| `remove` | deleted | +| `full` | the entire value is replaced, not just the match | + +Character counts are multibyte-aware. A `partial` match no longer than `keep` is masked entirely, since revealing any of it would reveal all of it. + +`mask`, `partial` and `remove` are translated into the operators of the same name. `full` is the pre-1.0 behaviour and condemns the whole value on one match; prefer a blocked key or a path rule where that is what you mean. + +### Capture Groups + +Some patterns need surrounding context to match confidently, but the context is not itself sensitive. Name the group holding the secret and the rest survives: + +```php +'aws_secret_key' => [ + 'pattern' => '/(aws_secret_access_key\s*=\s*)([A-Za-z0-9\/+]{40})/i', + 'capture' => 2, +], + +// aws_secret_access_key = [REDACTED] +``` + +If the named group did not participate in the match, the whole match is used instead. The shipped `url_with_auth` and `bearer_token` rules work this way, so the host of a credential URL and the word `Bearer` stay readable. + +### Validators + +A regex asserts shape only. `/\b(?:\d[ -]*?){13,16}\b/` matches order numbers and concatenated timestamps as readily as cards. A validator asserts that the value could be what the pattern claims, and a match that fails one is left alone: + +| Validator | Check | +| --- | --- | +| `luhn` | The payment card check digit, on 12 to 19 digits. | +| `iban` | ISO 13616 mod-97, on 15 to 34 characters. | +| `ssn` | US allocation rules: area not 000, 666 or 900 and above; group not 00; serial not 0000. | + +```php +Redactor::redact('order 2024010112000001 shipped'); // untouched: fails Luhn +Redactor::redact('paid with 4111111111111111'); // 'paid with ************1111' +``` + +A passing validator also raises the match's confidence. See [Confidence](#confidence). + +### Keywords + +A rule can name literals at least one of which must appear somewhere in the value, compared case-insensitively, before the pattern is tried: + +```php +'email' => ['pattern' => '/[^@\s]+@[^@\s]+/', 'keywords' => ['@']], + +'phone_bare' => [ + 'pattern' => '/(? ['phone', 'tel', 'mobile', 'cell', 'fax'], +], +``` + +Keywords do two jobs. The first is cost: "does this value contain an `@`" is one `str_contains()`, so almost every string in a log payload skips the email regex. The second is precision: a bare ten-digit run is a phone number in a value that says `phone` and a Unix timestamp almost everywhere else. + +The keyword must be in the value, not the key. A rule that should fire because of the key name is a [blocked key](#safe-and-blocked-keys). + +### Minimum Length + +A rule can state the shortest text it could possibly match, in bytes: + +```php +'aws_access_key' => ['pattern' => '/\b(?:AKIA|ASIA)[0-9A-Z]{16}\b/', 'min_length' => 20], +``` + +A shorter value skips the rule with one integer compare. Rules are sorted by `min_length` when the profile is built, so once the subject is shorter than a rule's minimum every rule after it is skipped too. Sorting changes only the order rules are *tried*; declared order still decides an equal-score overlap. + +The number must never exceed the true minimum or the rule misses real matches. When in doubt leave it out. Every shipped rule declares one. + +### Samples + +A rule can carry the texts it exists to catch, and texts it must leave alone: + +```php +'order_ref' => [ + 'pattern' => '/\bORD-\d{6}\b/', + 'samples' => ['ref ORD-123456'], + 'counter_samples' => ['ORD-12', 'ORDER-123456'], +], +``` + +`php artisan redactor:validate` runs every sample through the real detection path, with keywords, minimum length, validator and allow lists applied, and fails when a rule no longer detects a sample or detects a counter-sample. A regex edit that quietly stops matching what it was written for then fails CI instead of an audit. Every shipped rule carries both. + +### Dictionary Rules + +A rule can be a list of words instead of a regex. Product codenames, internal project names, a customer list: things no pattern can express and no model would know. + +```php +'codenames' => ['words' => ['Project Falcon', 'Orion'], 'entity' => 'codename'], +``` + +The words are compiled into one whole-word, case-insensitive alternation, longest first, so `Project Falcon` is one finding rather than two and `Orionids` is left alone. Every other rule option applies. An empty list throws. + +### Per-Rule Allow Lists + +A rule can carry exceptions scoped to that rule alone: + +```php +'email' => ['pattern' => '/[^@\s]+@[^@\s]+/', 'allow' => ['/@example\.com$/']], +``` + +Entries follow the same rules as the profile [allow-list](#allow-lists): a literal compared case-insensitively, or a regex when the entry is delimited like one. A rejected match is simply not a detection, so another rule can still report the same span. + +### Entity and Operator + +`entity` names what kind of thing the rule finds. It defaults to the rule name and is what `operators` keys on, so three phone rules sharing `'entity' => 'phone'` are governed by one `operators.phone` entry. + +A rule can also choose its own operator: + +```php +'card' => [ + 'pattern' => '/\b\d{16}\b/', + 'operator' => ['partial' => ['keep' => 4]], +], +``` + +Only a rule that explicitly sets `operator` or a non-default `mode` outranks the profile's `operators.default`. A rule with no preference defers to it. See [Precedence](operators-and-pseudonymisation.md#precedence). + +## Allow-Lists + +Some values look sensitive and are known not to be: the support address on every page, the sandbox card in every fixture, the example key in the docs. List them rather than weakening the pattern that finds them: + +```php +'allowlist' => [ + 'noreply@example.com', // a literal, trimmed and compared case-insensitively + '/^test-\d+@example\.com$/', // a regex, recognised by its delimiters +], +``` + +The allow-list is checked after detection, whichever detector reported the value: a pattern, entropy, a known secret, a blocked key or a path rule. The rules stay as strong as they were written and an allowed value is simply not a finding. A regex entry that cannot be evaluated allows nothing, since the failure mode of an allow-list is a leak. + +An entry is treated as a regex when its first character is not alphanumeric, a backslash or whitespace, and the matching closing delimiter appears at the end, optionally followed by modifiers. Anything else is a literal. + +## Path Rules + +A path says exactly where a value lives. Every other rule infers that from a key name or from the content. + +```php +'paths' => [ + 'request.headers.authorization' => 'redact', + 'user.*.email' => 'surrogate', + '**.password' => 'redact', + 'users[*].token' => 'redact', + 'debug' => 'preserve', +], +``` + +| Segment | Matches | +| --- | --- | +| `literal` | That key exactly, case-insensitively. | +| `*` | Any single level. | +| `**` | Any depth, including none. | +| `[*]` | A list index. `users[*].x` and `users.*.x` are the same pattern. | +| `[0]` | A specific index. `items[0]` and `items.0` are the same. | + +Each value is an operator, in any of the [three spellings](operators-and-pseudonymisation.md#configuring-operators). + +Paths are checked before anything else and, when one matches, *instead of* everything else: no key matching, no pattern scanning, no walk below the matched node. The more specific pattern always wins, scored by segment (a literal counts 3, `*` counts 2, `**` counts 1), so declaration order never matters, and `preserve` carves an exception out of a broader rule without disabling it. + +A path rule on a scalar gets the full operator range and is reported with a certain confidence and the rule name `path:`; the key is its entity. A path rule on an array or object supports `preserve`, `remove` and `nullify`; any other operator collapses the subtree to the replacement string, since masking or pseudonymising an array has no defensible meaning. The profile allow-list still applies to scalars. + +Paths compile once into a trie walked in lockstep with the payload, so the cost tracks the rules currently in play rather than the number configured. Two hundred path rules cost about the same as one. + +## Safe and Blocked Keys + +`blocked_keys` lists keys whose values are always redacted. `safe_keys` lists keys whose values are always preserved. Both are compared case-insensitively. + +```php +'safe_keys' => ['id', 'user_id', 'created_at', '*_count'], +'blocked_keys' => ['password', '*token*', '*key*', 'user_*_data'], +``` + +Two things about `safe_keys` matter more than they look: + +- A safe key preserves the **entire subtree**. `SafeKeysStrategy` ends the chain and stops the walk, so everything nested under a safe key is emitted untouched. Only list keys whose contents cannot carry sensitive data by construction: identifiers, timestamps, enumerations. A free-text field like `message` is not safe because it usually looks harmless. +- `SafeKeysStrategy` runs first in the shipped profiles, so a key listed in both lists is never redacted. `redactor:validate` reports the conflict. + +A value under a blocked key is reported with a certain confidence, the rule name `blocked_key`, and the lowercased key as its entity. That is what lets `operators.email` apply to `['email' => ...]` and to an address inside a message alike. A blocked key holding an array, boolean or null collapses to the replacement string, since there is no text for an operator to act on; `nullify` keeps the key and writes null. + +### Wildcards + +Both lists accept `*`: + +| Pattern | Matches | +| --- | --- | +| `password` | `password` exactly | +| `*token*` | any key containing `token`: `api_token`, `token_data`, `MyTokenField` | +| `password*` | any key starting with `password`: `password_hash`, `password_confirmation` | +| `*_key` | any key ending with `_key`: `private_key`, `api_key` | +| `user_*_token` | `user_api_token`, `user_auth_token` | +| `*` | every key | + +Lists are compiled once, and each pattern becomes the cheapest test for its shape: a hash lookup for exact names, `str_contains()` for `*word*`, `str_starts_with()` and `str_ends_with()` for one-sided wildcards. Only a pattern with an interior wildcard such as `user_*_token` reaches PCRE, compiled once. The shape of your list barely matters in practice. + +## Known Secrets + +Every other detector infers. This one knows: the application's own credentials are already in config, and a log line containing one of them verbatim is a leak whatever it looks like. + +```php +'known_secrets' => [ + 'values' => [env('LEGACY_SIGNING_KEY')], + 'config' => [ + 'app.key', // shipped default + 'services.stripe.secret', + 'database.connections.mysql.password', + 'services.acme', // an array: every string under it + ], +], +``` + +Matching is exact and case-sensitive. Values under 8 characters and nulls are skipped, so an unset secret in a local environment never fails the profile. A registered value is reported with a certain confidence, the rule name `known_secret` and the entity `known_secret`. + +A credential that only exists at runtime is registered the same way, for every profile: + +```php +Redactor::registerSecret($vault->read('signing-key')); +Redactor::registerSecret($token, entity: 'vault_token'); +``` + +`registerSecret()` returns false if the value was too short to register. + +## Confidence + +Binary matching forces a choice between noise and misses: the only way to quieten a rule is to weaken its regex everywhere. Detections carry a score instead. + +```php +'patterns' => [ + 'card' => ['pattern' => '/\b\d{16}\b/', 'confidence' => 0.3, 'validator' => 'luhn'], +], + +'min_confidence' => 0.5, +``` + +The base score comes from the rule. Two signals raise it: + +| Signal | Delta | When | +| --- | --- | --- | +| `validator` | +0.75 | The rule has a validator and the match passed it. | +| `context` | +0.25 | A credential keyword (`secret`, `token`, `password`, `apikey`, `bearer`, `key`, `card`, `cvv`, `ssn` and others) appears in the 40 bytes before the match, or in the key the value sits under. | + +Deltas apply to the remaining headroom rather than adding flat, so signals stack toward 1.0 without exceeding it: 0.3 with a validator becomes 0.825, and with a keyword too 0.87. The same pattern is therefore filtered out as noise on its own and reported when something corroborates it, without editing the pattern. + +Entropy detections start at 0.5, climb by up to 0.4 as the token's entropy clears its threshold, and gain the same context boost. Values found by a blocked key, a path rule or a known secret are certain (1.0). Recognised entities start at the recogniser's own score. `min_confidence` applies to all of them. + +Every finding explains itself. `inspect()` and `redactor:scan` report the score and the signals behind it: + +```json +{ + "rule": "card", + "confidence": 0.87, + "signals": [ + "base +0.30 (pattern \"card\" matched)", + "validator +0.75 (luhn checksum passed)", + "context +0.25 (a credential keyword appears alongside the match)" + ] +} +``` + +Scores map to labels at 0.9 (high), 0.6 (medium) and 0.3 (low); anything lower is very low. + +## How Detections Are Resolved + +The regex, entropy, known-secret and recognition strategies are *detectors*. They report what they found and where, and change nothing. Once every detector in the chain has seen a value, the context resolves the reports and rewrites the original string in one pass: + +1. Detections below `min_confidence` are dropped. +2. Where two detections overlap, the higher score wins. On an equal score the rule declared first in `patterns` wins, then the report that arrived first. +3. Detections whose value is on the allow-list are dropped. +4. Each surviving span is handed to its operator and written into the output left to right. + +Three things follow: + +- An API key beside an email address is not spared because the email matched first. Both are reported, both are rewritten. +- A surrogate written for one detection is never re-detected by the next detector. It has the same shape and entropy as the value it replaced, and a sequential chain would have redacted it again. +- Every finding's offset is a byte offset into the value you passed, so the scanner reports the right column for the second secret on a line. + +Length is deliberately not a criterion in step 2, since it would let a greedy general rule swallow the precise one beside it. A Luhn-validated card (0.6 + 0.75) outranks the bare digit run that also matched it, and `url_with_auth` declared ahead of `email` takes the password out of `https://user:pass@host` and leaves the host. + +A `preserve` operator reports the finding through `inspect()` without marking the payload redacted, which is what a scan that should only report wants. + +## PCRE Failures + +Every regex is evaluated fail-closed. If PCRE gives up on a pattern, because of the backtrack limit, the JIT stack limit or invalid UTF-8, the value is treated as sensitive rather than clean: the whole value is replaced, the failure is logged with the rule name, and the finding is reported with a certain confidence. + +The exceptions are the places where a failure would otherwise excuse a value. An allow-list entry, an entropy exclusion pattern or a safe-key pattern that cannot be evaluated allows nothing. A blocked-key pattern that cannot be evaluated blocks the key. diff --git a/docs/scanning.md b/docs/scanning.md new file mode 100644 index 0000000..d33e5b1 --- /dev/null +++ b/docs/scanning.md @@ -0,0 +1,260 @@ +# Scanning + +- [Introduction](#introduction) +- [Scanning Paths](#scanning-paths) +- [Profiles](#profiles) +- [Output Formats](#output-formats) + - [Table](#table) + - [JSON](#json) + - [SARIF](#sarif) + - [JUnit](#junit) +- [Failing the Build](#failing-the-build) +- [Confidence Filtering](#confidence-filtering) +- [Scanning Changes, Not Files](#scanning-changes-not-files) +- [Looking Through Encodings](#looking-through-encodings) +- [Baselines](#baselines) + - [The Ruleset Fingerprint](#the-ruleset-fingerprint) +- [Suppressing a Finding in Place](#suppressing-a-finding-in-place) +- [Verifying Credentials](#verifying-credentials) +- [The Pre-Commit Hook and Workflow](#the-pre-commit-hook-and-workflow) +- [Exit Codes](#exit-codes) +- [Options Reference](#options-reference) + +## Introduction + +`redactor:scan` runs a profile over files instead of payloads and reports where it found something. It is the same detection engine, so a rule you tune for logs is the rule that scans your repository, and every finding's excerpt is taken from the *redacted* text, so reports can be shared without publishing the secrets they report. + +```bash +php artisan redactor:scan +``` + +## Scanning Paths + +Pass files or directories; the default is the application's base path: + +```bash +php artisan redactor:scan path/to/file.txt +php artisan redactor:scan app/ config/ +``` + +Directories are walked with these exclusions: + +- Files matching `scan.exclude_patterns`, tested against the basename and the path relative to the scanned directory. A pattern ending in `/*` prunes the whole directory. +- Files larger than `scan.max_file_size` (10 MB by default). +- Binary files, when `scan.skip_binary` is true: a NUL byte in the first 8 KB, or content that is neither valid UTF-8 nor mostly printable. +- Files git already ignores, when `scan.respect_gitignore` is true. + +A file you name explicitly is scanned even if a pattern would exclude it. A path that does not exist is warned about and skipped. + +Each file is read as overlapping windows of lines (`scan.window_lines` and `scan.overlap_lines`, 512 and 4 by default), so memory stays flat whatever the file size. Windows overlap so a secret spanning a boundary, a PEM block or a wrapped connection string, is still found; the duplicate the overlap produces is dropped by rule, line and column. + +## Profiles + +The scanner uses `scan.profile`, which is `file_scan` unless you change it, or whatever `--profile` names: + +```bash +php artisan redactor:scan --profile=strict app/ +``` + +`file_scan` has no key-based strategies, since a file has no keys, and adds labelled rules such as `password_assignment` and `aws_secret_key` that only make sense in source and config files. See [Configuration](configuration.md#the-shipped-profiles-compared). + +## Output Formats + +### Table + +The default. Findings, not files, ranked by severity so the certain ones are read first: + +``` + Severity Rule Location Excerpt + HIGH aws_access_key app/config.env:3:19 AWS_ACCESS_KEY_ID=[REDACTED] + MEDIUM email app/seed.php:12:24 'contact' => '[REDACTED]', +``` + +Severity comes from confidence: `HIGH` at 0.9 and above, or for findings with no score such as a known secret; `MEDIUM` at 0.6; `LOW` at 0.3; `VERY LOW` below that. A credential confirmed live by [verification](#verifying-credentials) is `LIVE`, above everything else. Pass `--summary-only` to print the totals without the table. + +### JSON + +```bash +php artisan redactor:scan --output=json +``` + +One object per scanned file, with `path`, `ruleset`, `status` (`clean`, `findings` or `skipped`), `findings_count`, `findings`, `profile` and `error`. Each finding carries `rule`, `entity`, `line`, `column`, `excerpt`, `confidence`, `severity`, `signals`, `verification`, `commit`, `encoding`, `profile` and `fingerprint`. Nothing in it is the secret. + +### SARIF + +```bash +php artisan redactor:scan --output=sarif > redactor.sarif +``` + +SARIF 2.1.0, which GitHub code scanning renders inline on the pull request: + +```yaml +- run: php artisan redactor:scan --output=sarif > redactor.sarif +- uses: github/codeql-action/upload-sarif@v3 + with: + sarif_file: redactor.sarif +``` + +Severity maps onto SARIF levels so a low-confidence hit is a note rather than a merge blocker: `high` is `error`, `medium` is `warning`, anything else `note`. Each result carries the finding's fingerprint under `partialFingerprints`, its entity, confidence and signals under `properties`, and the redacted excerpt as the snippet. The ruleset fingerprint is recorded under the tool driver's properties. + +### JUnit + +```bash +php artisan redactor:scan --output=junit +``` + +JUnit XML for a CI dashboard that already renders test results: one test case per scanned file, one failure per finding, a skipped element for a file that could not be read. The excerpt is already redacted. + +Every format other than `table` suppresses the progress lines, so the output can be piped as-is. + +## Failing the Build + +```bash +php artisan redactor:scan --bail +``` + +Exits 1 when any finding survives the baseline and the confidence floor. Without `--bail` the command exits 0 whatever it finds. + +## Confidence Filtering + +```bash +php artisan redactor:scan --min-confidence=0.8 +``` + +Raises the bar without weakening any pattern. The value must be between 0 and 1 and is applied to the profile before scanning, so a low-scoring detection is never acted on rather than filtered out afterwards. Each finding reports its score, its severity and the signals behind it, so the threshold can be chosen on evidence. See [Confidence](rules.md#confidence). + +## Scanning Changes, Not Files + +A gate on commits cares about what is being added, not what was already there. Three modes scan only the lines a change adds, so a pre-existing finding never blocks a commit and a secret is caught on the line that introduces it: + +```bash +php artisan redactor:scan --staged # what is about to be committed +php artisan redactor:scan --diff=origin/main # what the working tree adds over a ref +php artisan redactor:scan --history # every line every commit ever added +php artisan redactor:scan --history=main..HEAD app/ # a range, and a pathspec +``` + +Findings are reported on their real line numbers in the new file. In history mode each finding names the commit that added it, as `abcd1234:path:line:column`, and a secret that a later commit removed is still found: it is still in the repository. + +With a git mode, the `paths` argument is passed to git as a pathspec rather than walked as directories. `scan.exclude_patterns` still apply. The command must run inside a git repository, and a git failure is reported and exits 1. + +The added lines of each change are scanned as one text, so a secret spanning two adjacent added lines is still found. + +## Looking Through Encodings + +A secret in a repository is often not written plainly. A credential URL in a JSON file reads `https:\/\/user:pass@host`, a key in a Kubernetes secret is base64, a token in a query string is percent-encoded. With `scan.decode` on (the default), the scanner decodes one layer deep and scans what comes out: + +| Encoding | What is decoded | +| --- | --- | +| `json` | Lines with JSON string escapes (`\/`, `\"`, `\uXXXX` and the rest). | +| `url` | Percent-encoded runs. | +| `base64` | Tokens of 20 or more base64 characters that contain upper case, lower case and a digit or symbol, and decode to printable text. | + +A finding inside an encoded span reports the encoding, is located at the span's position, and its excerpt is taken from the decoded, redacted text with the encoding as a prefix: `[base64] password=[REDACTED]`. Set `REDACTOR_SCAN_DECODE=false` to switch it off. + +Redaction of live payloads never decodes. That is a cost on every log line for a case the scanner is the right place to catch. + +## Baselines + +A repository with test fixtures or a documented example key can never go green without a baseline, so record what you have accepted and let CI fail only on new findings: + +```bash +php artisan redactor:scan --update-baseline # writes .redactor-baseline.json and exits 0 +php artisan redactor:scan --bail # now fails only on new secrets +``` + +The baseline path is `scan.baseline`, `.redactor-baseline.json` in the base path by default, or whatever `--baseline` names. `--update-baseline` needs one or the other. + +The file stores, for each accepted finding, a fingerprint plus the rule and path for a human reading the diff. The fingerprint is a hash of the rule, the path and the secret; the secret itself is never written, and because the line number is not part of it a finding stays accepted when the code around it moves. Only the fingerprint is matched. A baseline that cannot be parsed fails the command. + +### The Ruleset Fingerprint + +Every scan reports a short digest of the rules it ran: the patterns and their options, the entropy settings, the confidence floor and the key lists. It appears in JSON output, in SARIF under the tool's properties, and in the baseline it writes. + +Two runs with the same fingerprint are comparable. A baseline generated under a different fingerprint is warned about, since what it accepted may no longer mean the same thing; review it, or run `--update-baseline`. + +## Suppressing a Finding in Place + +A fixture, a documented example, a sandbox credential: mark the line and the scanner skips it, with the reason next to the code rather than in a baseline file: + +```php +$stripe = 'sk_test_4eC39HqLyjWDarjtT1zdp7dc'; // redactor:allow - Stripe's public test key +``` + +The marker is `redactor:allow`, anywhere on the same line. It suppresses every finding on that line. + +## Verifying Credentials + +A scan of a mature repository turns up hundreds of candidates: expired keys, examples in docs, fixtures, rotated credentials. A list that cannot separate the live ones from the dead is a list nobody triages. Verification asks each provider directly whether a detected credential still works. + +It also sends real secrets to third parties, so nothing happens unless all three of these agree: + +1. `scan.verification.enabled` is true, in the config file, reviewable in a diff. +2. The run passes `--verify`, a human decision per run. +3. The provider is listed under `scan.verification.verifiers`, which says who you are willing to tell. + +```php +'verification' => [ + 'enabled' => env('REDACTOR_SCAN_VERIFY', false), + 'verifiers' => ['github_token', 'stripe_key', 'slack_token'], +], +``` + +```bash +php artisan redactor:scan --verify +``` + +An empty `verifiers` list means none: enabling the feature and choosing who to trust with the secrets are separate decisions. Passing `--verify` with verification disabled or with an empty list fails the command with a message saying so. Before contacting anyone, the command names every host it will contact. Redaction itself can never trigger verification; only the scan command can, because nothing running unattended inside an application should be making outbound calls with secrets in them. + +The shipped verifiers: + +| Name | Host | Checks | +| --- | --- | --- | +| `github_token` | `api.github.com` | `GET /user`; 401 means dead. | +| `stripe_key` | `api.stripe.com` | `GET /v1/balance`, read-only; 401 means dead. | +| `slack_token` | `slack.com` | `POST /api/auth.test`; the `ok` field decides, since Slack answers 200 either way. | + +Each result is `active`, `inactive` or `unknown`. A confirmed-live credential is ranked `LIVE` (critical) above everything else. A check that could not complete is `unknown` and stays `high`, not `low`: failing to verify is not evidence of safety. A verifier that throws degrades its finding to `unknown` rather than abandoning the scan. The secret never reaches a finding, so it cannot escape through JSON, SARIF or a baseline. + +To add a verifier, see [Extending](extending.md#verifiers). + +## The Pre-Commit Hook and Workflow + +Publish the hook and the workflow: + +```bash +php artisan vendor:publish --tag=redactor-ci +git config core.hooksPath .githooks +``` + +This writes two files: + +- `.githooks/pre-commit` runs `php artisan redactor:scan --staged --bail` before every commit, so only the secret being committed now can fail it. Accept pre-existing findings into the baseline or mark them `redactor:allow`. +- `.github/workflows/redactor-scan.yml` runs on pull requests and on pushes to `main`. On a pull request it scans the branch's changes over its base (`--diff=origin/ --bail --output=sarif`); on `main` it scans the whole tree against the committed baseline. Either way it uploads the SARIF to GitHub code scanning, so findings render inline on the diff. It checks out with `fetch-depth: 0`, which the diff and history modes need. + +## Exit Codes + +| Code | When | +| --- | --- | +| `0` | The scan completed. With `--bail`, nothing was found beyond the baseline. `--update-baseline` wrote the file. | +| `1` | `--bail` and at least one finding. Also: an unknown `--output`, a `--min-confidence` outside 0 to 1, a baseline that could not be parsed, a profile that could not be resolved, `--verify` without verification enabled and a verifier listed, a git failure or a path outside a git repository in a git mode, `--update-baseline` without a path or that could not be written. | + +## Options Reference + +``` +redactor:scan + {paths?*} Paths to scan (files or directories, defaults to base_path); with a git mode, a pathspec + {--profile=file_scan} Redaction profile to use + {--bail} Exit with code 1 if findings are detected + {--summary-only} Do not display per-file results + {--output=table} Output format (table|json|sarif|junit) + {--staged} Scan only the lines staged for commit + {--diff=} Scan only the lines the working tree adds over this ref, e.g. origin/main + {--history=} Scan the lines added by every commit, optionally in a range like main..HEAD + {--min-confidence=} Ignore findings scoring below this (0-1) + {--verify} Check detected credentials against their providers (sends them off this machine) + {--baseline=} Path to a baseline file of accepted findings + {--update-baseline} Write the current findings to the baseline file and exit 0 +``` + +`--staged`, `--diff` and `--history` are checked in that order; the first one present wins. diff --git a/docs/testing.md b/docs/testing.md new file mode 100644 index 0000000..d320f93 --- /dev/null +++ b/docs/testing.md @@ -0,0 +1,134 @@ +# Testing + +- [Introduction](#introduction) +- [Faking the Redactor](#faking-the-redactor) + - [Assertions](#assertions) + - [Inspecting Calls](#inspecting-calls) +- [Validating Profiles](#validating-profiles) +- [Rule Samples](#rule-samples) +- [Testing Surrogates](#testing-surrogates) +- [The Package's Own Tests](#the-packages-own-tests) + +## Introduction + +Redaction is a runtime promise, and a promise nobody tests is one that quietly stops being kept.

Resolves the profile, which throws on any invalid value with the config path in the message. +2. Reports any key listed in both `safe_keys` and `blocked_keys`. `SafeKeysStrategy` runs first, so such a key is silently never redacted. +3. Reports any entry in `strategies` that is neither a class implementing `Strategy` nor a registered custom strategy name. +4.

Run it in CI and at deploy time; a broken profile otherwise throws at log time, where it is replaced rather than emitted. + +The same check is available in code as `Redactor::validateProfiles()`, which returns `profile => error message` for the broken ones. + +## Rule Samples + +Every rule can carry the texts it must detect and the texts it must leave alone: + +```php +'order_ref' => [ + 'pattern' => '/\bORD-\d{6}\b/', + 'samples' => ['ref ORD-123456'], + 'counter_samples' => ['ORD-12', 'ORDER-123456'], +], +``` + +`redactor:validate` checks each sample with the rule's keywords, minimum length, validator and allow lists applied, and names the rule and the sample that failed: + +``` +rule "order_ref" does not detect its sample "ref ORD-12" +rule "digits" detects its counter-sample "started at 1694600000" +``` + +A sample is checked against the rule that carries it, so another rule matching the same text neither passes nor fails it. Every shipped rule carries both, which is how the package's own test suite proves the shipped patterns still catch what they were written for. + +## Testing Surrogates + +Surrogates are only stable for a given key, so a test that asserts a specific surrogate needs a known one: + +```php +config()->set('redactor.pseudonymization.key', 'a-test-pseudonymization-key-of-sufficient-length'); + +expect(Redactor::redact('alice@customer.com', 'observability')) + ->toBe(Redactor::redact('alice@customer.com', 'observability')); +``` + +Most tests need only stability, which the example above asserts without hard-coding a surrogate.

Read them before upgrading. + +**Redaction now replaces the matched span, not the whole value.** `redact('User bob@example.com placed order 123')` returns `'User [REDACTED] placed order 123'` rather than `'[REDACTED]'`. If a rule must condemn the whole value on one match, give it `'mode' => 'full'`; if the intent was "this key is always sensitive", a blocked key or a path rule says so directly. + +**Detections are collected and the value rewritten once.** The regex and entropy strategies no longer rewrite the string as they go. They report, the context resolves overlaps and applies the confidence floor, and the original value is rewritten in one pass. Of two overlapping reports the higher score wins, then the rule listed first. A custom strategy that relied on seeing the string *after* the regex strategy rewrote it now sees the original; implement `DetectingStrategy` and report through `$context->collect()` to join the resolution. + +**Findings for a `preserve` operator are reported without marking the payload redacted.** A scan profile that only reports no longer sets `wasRedacted`. + +**`safe_keys` preserves the entire subtree.** Everything nested under a safe key is emitted untouched. The shipped profiles no longer list `message`, `title`, `url`, `path`, `ip`, `user_agent`, `source` or `target` as safe: all of them are free text or personal data, and with them safe the values were emitted verbatim. `session_id` was listed as both safe and blocked and is now blocked only. If you copied the 0.1.0 lists into your own profile, remove those keys; `redactor:validate` reports any key in both lists. + +**Long strings are truncated and scanned, not replaced.** A value over `max_value_length` keeps its head, which the remaining strategies still inspect, followed by `[REDACTED] (String truncated: 65536 characters, 5000 kept)`. Set `'large_string_behavior' => 'redact'` on a profile to restore the old wholesale replacement. + +**Throwables, dates, enums and closures pass through the walk untouched.** A Throwable used to encode to `{}` and reach the formatter as `[]`, losing the stack trace; a Carbon instance was exploded into its `toArray()` components. Key rules still apply, so `['secret' => $enum]` is still redacted. If you relied on a date being turned into an array, convert it yourself before redacting. + +**Blocked keys go through operators.** The key name is the entity, so `operators.email` applies to a value under an `email` key. Findings from a blocked key now carry the value they matched and a certain score. A blocked key holding an array, boolean or null still collapses to the replacement string. + +**The pseudonymisation salt is shared across profiles.** It used to default to the profile name, so two channels on different profiles produced different surrogates for the same user and could not be joined. Surrogates produced before the upgrade will not match surrogates produced after it. Set a profile's own `pseudonymization.salt` to break correlation on purpose. + +**Monolog integration moved to a processor.** `RedactorTap` pushes `RedactorProcessor`, which redacts message, context and extra without touching the channel's output format. Channels that used `CustomLogTap` had their formatter replaced with the package's own line format; with `RedactorTap` they keep the formatter they were configured with, so a channel whose output was the package's format will change format. Use `RedactorFormatterTap` to keep the old behaviour. + +**Scan findings are structured.** Each finding carries rule, line, column and a redacted excerpt instead of one opaque `full_content_redacted` record per file. Anything parsing the JSON output needs updating. See [The Scan Command](#the-scan-command). + +**Invalid configuration now throws** with the offending path named, instead of silently falling back to a default. A value that used to be ignored, such as a non-numeric `max_depth`, now fails the profile. Run `php artisan redactor:validate` before deploying. + +**Redaction metadata no longer corrupts the payload.** `_redacted` is never added to a list, since a string key would turn a JSON array into an object, and a caller's own `_redacted` key is never overwritten. If you read the marker to know whether anything matched, use `inspect()->wasRedacted` instead. + +**Documented environment variables now take effect.** `REDACTOR_MAX_OBJECT_SIZE` was silently ignored and `REDACTOR_SCAN_MAX_FILE_SIZE` crashed the scan command. If either is set in your environment, it now applies. + +**Scanner exclude patterns now work.** `vendor/*` and `node_modules/*` matched nothing in 0.1.0, so every dependency was scanned. They now match, and binary and gitignored files are skipped too. A scan that used to report findings in `vendor/` will stop. + +**PCRE failures fail closed.** A pattern that errors, on the backtrack limit or bad UTF-8, used to let the value through; it now replaces the value and logs the rule. A rule that was silently never matching may now redact everything it is given, which `redactor:validate` and the rule's samples will surface. + +**Entropy is measured per character, not per byte, and can be judged per alphabet.** Non-ASCII text scores lower than before, and the shipped profiles judge hex against 3.0 and base64 against 4.5 through `charset_thresholds`. Entropy detections now carry a score and go through `operators` and `min_confidence`, which they bypassed before. + +**Checksum validators reject values of the right shape that cannot be real.** The shipped `credit_card`, `ssn` and `iban` rules now validate, so an order number that happens to have 16 digits is left alone. + +**Recursion is depth-bounded and cycle-aware.** A self-referencing `toArray()` used to exhaust memory; it is now replaced at `max_depth` or on the first repeated object. + +**The logging path never throws.** A bad profile no longer takes the channel down, and diagnostics cannot re-enter the logger that raised them. + +**`RedactorFormatter::formatBatch()` formats every record.** It used to return only the first. + +## Configuration Keys That Changed Meaning + +| Key | Before | Now | +| --- | --- | --- | +| `safe_keys` | Preserved the scalar; documented wildcards did not work. | Preserves the whole subtree; wildcards work. | +| `patterns.` | A regex whose match condemned the whole value. | A regex whose match is replaced in place, or a full rule with `mode`, `keep`, `mask_character`, `capture`, `validator`, `entity`, `confidence`, `operator`, `keywords`, `min_length`, `samples`, `counter_samples`, `allow` or `words`. | +| `max_value_length` | Replaced the whole string. | Truncates and scans the head; see `large_string_behavior`. | +| `mark_redacted` | Wrote `_redacted` into any array, lists included, overwriting an existing key. | Associative arrays only, never overwrites, never written into HTTP responses or MCP structured content. | +| `shannon_entropy.threshold` | Judged every token, measured per byte. | Judged only tokens whose alphabet has no `charset_thresholds` entry, measured per character. | +| `scan.exclude_patterns` | Matched basenames only. | Matches basename and relative path; `dir/*` prunes the directory. | +| `non_redactable_object_behavior` | Unchanged in meaning, but Throwables and dates were walked like any other object and lost their content. | Throwables, dates, enums and closures pass through whole; the setting applies only to objects that can be neither `toArray()`'d nor JSON-encoded. | + +New keys, all optional with safe defaults: `large_string_behavior`, `max_depth`, `min_confidence`, `operators`, `paths`, `allowlist`, `known_secrets`, `recognition`, `shannon_entropy.charset_thresholds`, per-profile `pseudonymization`; and at the top level `pseudonymization`, `tokenization`, `events`, `scan.skip_binary`, `scan.respect_gitignore`, `scan.window_lines`, `scan.overlap_lines`, `scan.decode`, `scan.verification` and `scan.baseline`. See [Configuration](configuration.md). + +## Renamed Rules + +The shipped patterns were reorganised into two shared lists spread into every profile. If you reference rule names, in a baseline, a listener on `RedactionPerformed`, or `assertFinding()`, these changed: + +| 0.1.0 rule | Profile | Now | +| --- | --- | --- | +| `phone_simple` | `default`, `file_scan` | `phone_formatted`, `phone_e164` and `phone_bare` in every profile. | +| `phone` | `strict` | Removed. It matched any run of seven digits and spaces. | +| `api_key_stripe` | `file_scan` | `stripe_key`, in every profile. | +| `jwt_token` | `file_scan` | `jwt`, in every profile. | +| `jwt` | `strict` | `jwt`, with the shared pattern. | +| `aws_secret_key` | `file_scan` | Still `file_scan` only, but now requires a label such as `aws_secret_access_key =` before it; it used to match any 40-character alphanumeric run. | +| `url_with_auth` | all | Same name; any scheme, and only the password is replaced. | + +Credential rules that were `file_scan` only in 0.1.0, or absent altogether (`bearer_token`, `private_key_block`, `slack_token`, `anthropic_key`, `openai_key`, `google_api_key`, `sendgrid_key`), now run in `default`, `strict` and `observability` as well. Expect more findings from those profiles. + +## The Scan Command + +`redactor:scan` gained `--output=sarif`, `--output=junit`, `--staged`, `--diff`, `--history`, `--min-confidence`, `--verify`, `--baseline` and `--update-baseline`. The `--output=json` structure changed: each file object now carries `ruleset`, `status`, `findings_count` and a `findings` array of structured findings. See [Scanning](scanning.md#output-formats). + +Baselines did not exist in 0.1.0, so there is nothing to migrate; generate one with `--update-baseline` after upgrading. + +## Checklist + +1. Update `composer.json` to PHP 8.3+ and Laravel 12 or 13, and remove any direct dependency on the package's old transitive requirements. +2. Replace `CustomLogTap` with `RedactorTap` in `config/logging.php`, or with `RedactorFormatterTap` if the channel must keep the package's line format. +3. Replace `ReadactFormatter` with `RedactorFormatter` and `RedactionStrategyInterface` with `Strategies\Contracts\Strategy`. +4. Replace `getAvailableProfiles()`, `profileExists()` and `getStrategies()` with `profiles()`, `hasProfile()` and `strategies()`; replace `redactWithMetadata()` with `inspect()`. +5. Replace `addStrategy()` and `removeStrategy()` with profile configuration; call `calculateShannonEntropy()` and `isCommonPattern()` on `ShannonEntropyStrategy`. +6. Re-publish the config (`vendor:publish --tag=redactor-config --force`) or merge the new keys by hand, and remove free-text keys from any `safe_keys` list you copied. +7. Run `php artisan redactor:validate`. +8. If you export logs elsewhere, note that surrogates change once because the salt no longer includes the profile name. +9. Run `php artisan redactor:scan --update-baseline` if the scanner should start green, and publish the hook and workflow with `vendor:publish --tag=redactor-ci`.

A strategy with none of them replaces the value outright and ends the chain. diff --git a/src/Recognition/BatchRecognizer.php b/src/Recognition/BatchRecognizer.php new file mode 100644 index 0000000..e069050 --- /dev/null +++ b/src/Recognition/BatchRecognizer.php @@ -0,0 +1,27 @@ + $texts + * @param array $entities the recogniser's own labels to look for; empty means all + * @return array> spans per input index, offsets relative to that text + * + * @throws \Throwable when the recogniser could not answer + */ + public function recognizeMany(array $texts, string $language, array $entities, float $scoreThreshold): array; +} diff --git a/src/Recognition/Recognizers/PresidioRecognizer.php b/src/Recognition/Recognizers/PresidioRecognizer.php index 6d94865..fb4ac4e 100644 --- a/src/Recognition/Recognizers/PresidioRecognizer.php +++ b/src/Recognition/Recognizers/PresidioRecognizer.php @@ -5,8 +5,8 @@ namespace Kirschbaum\Redactor\Recognition\Recognizers; use Illuminate\Support\Facades\Http; +use Kirschbaum\Redactor\Recognition\BatchRecognizer; use Kirschbaum\Redactor\Recognition\RecognizedSpan; -use Kirschbaum\Redactor\Recognition\Recognizer; use RuntimeException; /** @@ -19,8 +19,21 @@ * says, which should never be the request path: a model call costs * milliseconds where the rule engine costs microseconds. */ -class PresidioRecognizer implements Recognizer +class PresidioRecognizer implements BatchRecognizer { + /** + * The separator between texts joined into one request. + * + * No entity spans a blank line, so a span that crosses one is an artefact + * of the join and is dropped rather than split. + */ + public const SEPARATOR = "\n\n"; + + /** + * The most characters sent in one request. + */ + public const BATCH_CHARACTERS = 60000; + /** * Create a new Presidio recognizer instance. */ @@ -45,6 +58,95 @@ public function withEndpoint(string $url, float $timeout): self return new self($url, $timeout); } + /** + * Recognise entities in many texts with as few requests as the size cap allows. + * + * Presidio's contract takes one text, so the texts are joined with a blank + * line between them, sent together, and each span is handed back to the + * text it fell in with its offsets made relative to that text. + * + * @param array $texts + * @param array $entities + * @return array> + * + * @throws RuntimeException + */ + public function recognizeMany(array $texts, string $language, array $entities, float $scoreThreshold): array + { + $results = []; + + foreach ($this->chunk($texts) as $chunk) { + $joined = implode(self::SEPARATOR, $chunk); + $spans = $this->recognize($joined, $language, $entities, $scoreThreshold); + + foreach ($this->segments($chunk) as $index => [$start, $end]) { + $results[$index] = []; + + foreach ($spans as $span) { + if ($span->start >= $start && $span->end <= $end) { + $results[$index][] = new RecognizedSpan($span->entity, $span->start - $start, $span->end - $start, $span->score); + } + } + } + } + + return $results; + } + + /** + * Split the texts into request-sized groups, keeping their indexes. + * + * @param array $texts + * @return array> + */ + private function chunk(array $texts): array + { + $chunks = []; + $current = []; + $length = 0; + $separator = mb_strlen(self::SEPARATOR, 'UTF-8'); + + foreach ($texts as $index => $text) { + $characters = mb_strlen($text, 'UTF-8'); + + if ($current !== [] && $length + $separator + $characters > self::BATCH_CHARACTERS) { + $chunks[] = $current; + $current = []; + $length = 0; + } + + $current[$index] = $text; + $length += ($length === 0 ?
