From 752fc38f50ae1886efc15288a431941de5192bde Mon Sep 17 00:00:00 2001 From: David Hook Date: Sat, 5 Sep 2026 23:49:26 +1000 Subject: [PATCH 01/37] camellia: add bouncycastle-camellia, a constant-time, table-free Camellia ported from bc-java New crate `crypto/camellia` (`bouncycastle::camellia`): the Camellia block cipher (RFC 3713) with 128-, 192- and 256-bit keys as a raw keyed permutation implementing ElectronicCodeBook -- Camellia_128 / Camellia_192 / Camellia_256 over a sealed CamelliaParams -- ported from BC Java's CamelliaEngine and CamelliaLightEngine and commented line by line against the RFC. The S-boxes are a 121-gate Boolean circuit (32 AND, 74 XOR, 9 XNOR, 6 NOT) over eight u32 bit-planes rather than the Java engines' tables (4 KiB, or 256 B in the light engine), so there is no secret-indexed memory access in the cipher or the key schedule. SBOX1 is GF(2^8) inversion between two affine maps -- a decomposition found by exhaustive search against the RFC's table: of the 256 input constants exactly one (0xc5) admits it, unique up to the inverse's own symmetries -- so the non-linear section of the Boyar-Peralta AES circuit (copied from aes) does the inversion, with generated affine layers chosen among the 2040 equivalent forms for the fewest gates. SBOX2/3/4 are one-bit byte rotations of SBOX1, which on bit-planes are plane renumberings under compile-time position masks, so one circuit serves all four. The u32 planes hold four blocks' F-inputs per pass: encrypt_4blocks/decrypt_4blocks are the natural unit, the trait's blocks8 is two passes and blocks2 uses two lanes. The four-lane u32 design keeps the per-call working set near 160 B (half the u64 alternative), which is the "lowmemory" in the name. One stored schedule (208 B / 272 B, in a Secret) serves both directions via the Sec 2.3.3 subkey swap. Also: Camellia_CBC_128/192/256 aliases over bouncycastle-modes; camellia128-cbc / camellia192-cbc / camellia256-cbc CLI subcommands sharing cbc_cmd.rs; criterion bench; mem_usage_benches harness; umbrella re-export; release notes. Verified against RFC 3713 Appendix A (all three key lengths, every lane and slot of the four-, eight- and two-block paths, both directions); all 3840 vectors of NTT's CRYPTREC test-vector file t_camellia.txt (ten keys per key length, 128 single-bit plaintexts each, both directions, transcribed mechanically); the nine vectors of BC Java's CamelliaTest (RFC 3713 and NESSIE); the CAMELLIA-*-CBC vectors of OpenSSL's evpciph_camellia.txt through the CBC aliases; a transcription of CamelliaLightEngine kept in the tests, which the engine must agree with on thousands of keys and blocks of every length in every lane and both directions; ElectronicCodeBook conformance for all three types; and the CLI against the OpenSSL vectors. cargo mutants: 552 mutants, 533 caught, 6 unviable, 13 missed -- all thirteen proven |/^ equivalences on disjoint bits or the documented Boyar-Peralta t37 gate, commented at the site.

Camellia_CBC_256::::decrypt(&key, &iv, &mut data).unwrap(); +//! assert_eq!(data, plaintext); +//! ``` +//! +//! There is no one-shot static on the permutation, because `Camellia_128::new(&key)?.encrypt_block(..)` +//! already *is* the one shot. Data-level one-shots belong to the modes of operation, which take +//! arbitrary-length input and generate their own initialisation data. +//! +//! # Design +//! +//! Camellia is an 18-round (128-bit key) or 24-round (192- and 256-bit key) Feistel network over +//! two 64-bit halves, with a key-dependent linear `FL`/`FLINV` layer inserted every six rounds +//! (Sec 2.3) and 64-bit whitening keys XORed in before and after. The round function `F` +//! (Sec 2.4.1) XORs a subkey into the half, puts its eight bytes through four S-boxes -- `SBOX1` +//! and three one-bit rotations of it -- and mixes them with a byte-wise linear map `P`. The key +//! schedule (Sec 2.2) derives two or three 128-bit intermediate keys with six applications of `F` +//! under fixed constants, then takes every subkey as half of a rotation of one of them, so it is +//! cheap: Camellia's "key agility" is one of its design goals. Decryption is the same network with +//! the subkeys in reverse (Sec 2.3.3). +//! +//! ## Why not a lookup table +//! +//! Sec 2.4.1 presents `SBOX1` as a table, and BC Java's engines store tables -- `CamelliaEngine` +//! four 1 KiB tables with `P` folded in, `CamelliaLightEngine` one 256-byte table. A table indexed +//! by a byte of the state is indexed by secret data, so on any CPU with a data cache the memory +//! access pattern, and hence the timing, depends on the key and the data. That is the classic +//! cache-timing attack on table-driven block ciphers, and it is not fixable while the lookup +//! remains -- in the cipher or in the key schedule, whose `F` calls go through the S-boxes too. +//! +//! ## The S-box as a circuit +//! +//! This crate has no table outside its tests. `SBOX1` has the same algebraic shape as the AES +//! S-box -- an affine map, inversion in GF(2^8), and another affine map -- a decomposition found +//! here by exhaustive search against the Sec 2.4.1 table, not taken from recall: of the 256 +//! possible input constants exactly one admits such a decomposition, and it is unique up to the +//! inverse's own symmetries. The search was carried out in the AES representation of the field, +//! so the 62-gate non-linear section of the Boyar-Peralta AES circuit, copied verbatim from +//! `bouncycastle-aes`, does the inversion, with generated affine top and bottom layers +//! pinned by an exhaustive 256-input test. The whole S-box is 121 gates: 32 AND, 74 XOR, 9 XNOR, +//! 6 NOT. The `sbox` module docs give the full derivation. +//! +//! `SBOX2`, `SBOX3` and `SBOX4` are `SBOX1` with the output byte rotated left by one, rotated +//! right by one, and the input byte rotated left by one (Sec 2.4.1). On bit-planes a byte rotation +//! is a renumbering of the planes, so the one circuit serves all four: the rotations are applied +//! only at the byte positions that need them, selected by compile-time masks. +//! +//! A round substitutes eight bytes per block, and the circuit's eight `u32` planes hold 32 byte +//! positions, so the engine works on **four blocks at once**: each round forms the argument of `F` +//! for every block, splits the four 64-bit words into eight 32-bit halves, transposes them into +//! planes, runs the circuit once, transposes back, and finishes the round per block. The blocks +//! never mix. Everything else in +//! the cipher -- `P`, `FL`, `FLINV`, the whitening -- is XOR, AND and OR with key words, and +//! rotations, all already constant-time on words, so the rest of the engine is a direct, +//! spec-literal port: 64-bit halves as in the RFC rather than the 32-bit quarters of BC Java, +//! and `P` computed with the Java engine's five-rotation trick, which is checked against the +//! RFC's byte formulas in a test. +//! +//! Beyond the S-box, the port differs from the Java engines in three ways: one stored schedule +//! serves both directions (Java lays the subkeys out for the direction requested at `init`); the +//! block methods are infallible (the run-time buffer and initialisation checks are compile-time +//! facts here); and the constructors require a key tagged as a symmetric cipher key of at least +//! the strength its length implies, as every cipher in this workspace does. +//! +//! ## Why "lowmemory" +//! +//! Two things. First, no tables: BC Java's `CamelliaEngine` carries 4 KiB of them and even the +//! `CamelliaLightEngine` 256 bytes, all indexed by secret data; here the S-box is code. Second, +//! the working set. Eight `u64` planes would take eight blocks per pass and double the throughput +//! on a 64-bit machine, but every per-call buffer -- the block state, the planes, their copy during +//! the byte rotations -- would double with them. Four lanes over `u32` planes keep the whole +//! per-call working state near 160 bytes, and cost nothing on a 32-bit target, where a `u64` +//! operation is two instructions anyway. +//! +//! # Memory Usage +//! +//! No heap allocation and no lookup tables. The persistent state is the subkeys of Sec 2.2 -- +//! four whitening keys, one round key per round, and two `FL`/`FLINV` keys per `FL` layer, 64 bits +//! each: +//! +//! | Type | Key | Rounds | Subkeys (persistent) | Tables | +//! |---|---|---|---|---| +//! | [`Camellia_128`] | 16 B | 18 | 26 x 8 = 208 B | 0 B | +//! | [`Camellia_192`] | 24 B | 24 | 34 x 8 = 272 B | 0 B | +//! | [`Camellia_256`] | 32 B | 24 | 34 x 8 = 272 B | 0 B | +//! +//! Per-call stack usage is the four-block working state -- two 64-bit halves per block, 64 +//! bytes -- plus the eight `u32` planes of the S-box argument (32 bytes), their copy during the +//! rotations (32 bytes), and the circuit's temporaries, most of which the compiler keeps in +//! registers. +//! Measure with `cargo run --release -p mem_usage_benches --bin bench_camellia_mem_usage`. +//! +//! For comparison, BC Java's `CamelliaEngine` carries 4 KiB of tables and `CamelliaLightEngine` +//! 256 bytes, both on top of a 272-byte subkey array sized for the largest key. +//! +//! # Security Considerations +//! +//! ## A block permutation is not a cipher +//! +//! [`Camellia_128`] and its siblings transform exactly 16 bytes. Using one directly on data means +//! ECB, which is not confidential: identical plaintext blocks produce identical ciphertext blocks, +//! so structure in the plaintext survives encryption. **Do not do it.** Use a mode of operation, +//! and prefer an authenticated one so that ciphertext tampering is detected. RFC 3713 Sec 3 itself +//! assigns object identifiers only to Camellia in CBC mode. +//! +//! ## Constant-time properties +//! +//! By construction there is no secret-dependent memory access and no secret-dependent branch, in +//! the cipher *or* in the key schedule: the six `F` calls of Sec 2.2 go through the same circuit +//! as the rounds. The only branches are the round loop and the lane loops, which count over public +//! constants, and the odd/even and every-sixth-round tests on the public round counter. +//! +//! Caveats worth stating plainly: +//! +//! * The Rust compiler makes no guarantee it will preserve this. The code is written so that the +//! natural code generation is straight-line, and `#![forbid(unsafe_code)]` rules out the usual +//! ways of forcing the issue, but the property is not contractual. +//! * The four-block working state is not scrubbed after a call. Only the subkeys (and, during +//! expansion, `KL`, `KR`, `KA`, `KB` and the `D1`/`D2` temporaries) are wrapped in `Secret`, and +//! so only they are guaranteed to be zeroized on drop. +//! * Constant-time execution says nothing about power or electromagnetic side channels. +//! +//! ## Security strength +//! +//! RFC 3713 Sec 4 reports no differential or linear characteristic with probability above +//! `2^-128` for the full 18 rounds. Each variant's `MAX_SECURITY_STRENGTH` is its key length: +//! 128, 192 or 256 bits. +//! +//! # Provenance +//! +//! * **Source implementation: Bouncy Castle Java `org.bouncycastle.crypto.engines.CamelliaEngine` +//! and `CamelliaLightEngine`**, whose `SIGMA` constants, `camelliaF2` linear layer, +//! `camelliaFLs` and subkey layout this crate reproduces, and whose `SBOX1` table is the +//! reference the circuit is verified against. A direct transcription of `CamelliaLightEngine` +//! lives in the tests (`tests/common/mod.rs`) and the engine is checked against it on thousands +//! of inputs. +//! * **Normative reference: RFC 3713**, "A Description of the Camellia Encryption Algorithm" +//!

Java's `CamelliaEngine` and `CamelliaLightEngine` both store tables (four 1 KiB `u32` tables +//! with the P-function folded in, and one 256-byte table, respectively). A table indexed by a +//! byte of the state is indexed by *secret data*, and on any CPU with a data cache the access +//! pattern -- hence the timing -- depends on that secret. That is the standard cache-timing side +//! channel of every table-driven block cipher, and it cannot be closed while keeping the lookup. +//! +//! So this module has no table (outside its tests). It computes the same function as the Sec 2.4.1 +//! table with AND, XOR, XNOR and NOT gates applied to the bit-planes of [`crate::bitslice`]. Every +//! operation is a straight-line word operation on public *positions*, so there is no +//! secret-dependent memory access and no secret-dependent branch. This is the only place in the +//! crate where secret data meets non-linear logic; everything else is XOR, AND/OR with key words, +//! and rotates. +//! +//! Because the planes hold the eight bytes of one F-function input from each of four blocks, one +//! pass of the circuit is the whole S-box layer of a round for four blocks at once. +//! +//! # What the circuit computes, and where it came from +//! +//! `SBOX1` has the same algebraic shape as the AES S-box: an affine map, inversion in GF(2^8), and +//! another affine map. Writing `inv` for inversion in the AES field (`x^8 + x^4 + x^3 + x + 1`, +//! with `inv(0) = 0`), and `M`, `N` for 8x8 matrices over GF(2) given by their columns (column +//! `i` is the image of input bit `i`, bit 0 least significant): +//! +//! ```text +//! SBOX1(x) = N * inv(M * x xor 0x82) xor 0x6e +//! +//! M columns: 0x38, 0x84, 0xe7, 0xbb, 0x94, 0xff, 0x0d, 0x50 +//! N columns: 0xeb, 0x38, 0x5c, 0x19, 0xc5, 0xf8, 0xb5, 0x41 +//! ``` +//! +//! The input constant `0x82` is `M * 0xc5`, so equivalently `SBOX1(x) = N * inv(M * (x xor +//! 0xc5)) xor 0x6e`. This decomposition was **found by search, not recalled**: for each of the +//! 256 possible input constants the remaining linear equivalence to `inv` was searched +//! exhaustively (the search fixes the multiplicative and Frobenius self-equivalences of `inv`, +//! which is what makes it finite), against the table extracted from the text of RFC 3713. Exactly +//! one constant, `0xc5`, admits a decomposition, and it is unique up to those self-equivalences. +//! The 2040 equivalent forms give circuits of different sizes; the one above was chosen for the +//! fewest gates. +//! +//! Because both S-boxes are inversion between affine maps, the AES inversion circuit does +//! Camellia's work directly -- the field isomorphism is absorbed into `M` and `N`, since the +//! search was carried out in the AES representation. The circuit below is therefore +//! +//! * a **top affine layer**, generated: `M * x xor 0x82` composed with the Boyar-Peralta input +//! basis change, as one affine map from the eight input planes to the 22 signals the +//! non-linear section consumes; +//! * the **non-linear section** of the 113-gate Boyar-Peralta AES circuit, **copied verbatim** +//! from `bouncycastle-aes` (`src/sbox.rs`, itself a transcription of Peralta's +//! `SLP_AES_113.txt`): 32 AND and 30 XOR gates computing the inverse in a tower-field +//! representation; +//! * a **bottom affine layer**, generated: the tower field back to the AES polynomial basis, then +//! `N * . xor 0x6e`, as one affine map from the 18 non-linear outputs to the eight output planes. +//! +//! The two affine layers were fitted by linear algebra over GF(2) (the bottom one by solving for +//! the linear map from the non-linear section's outputs to `inv`, on all 256 inputs) and reduced +//! with a greedy common-subexpression pass. The result is 121 gates: 32 AND, 74 XOR, 9 XNOR, +//! 6 NOT (31 in the top layer, 62 in the non-linear section, 28 in the bottom layer). The +//! generator verified the assembled circuit -- the emitted text, re-evaluated -- against the table +//! before any of it was written here, and `test_sbox_matches_rfc_3713_sbox1` re-verifies all 256 +//! inputs in Rust. The gate list is not meaningful line by line and should not be "tidied". +//! +//! # The other three S-boxes +//! +//! Sec 2.4.1 defines `SBOX2[x] = SBOX1[x] <<< 1`, `SBOX3[x] = SBOX1[x] <<< 7` and +//! `SBOX4[x] = SBOX1[x <<< 1]`: rotations of the output byte, or of the input byte, by one bit. +//! On bit-planes a byte rotation is a *renumbering of the planes*, so [`sboxes`] runs the one +//! circuit for all 32 byte positions and applies the rotations only at the positions that need +//! them, with public position masks derived from the layout of [`crate::bitslice`]: plane `k` at +//! those positions is +//! taken from plane `k - 1` (rotate left) or `k + 1` (rotate right). No second circuit, and no +//! secret-dependent selection -- the masks are compile-time constants. +//! +//! # Bit numbering +//! +//! Plane `k` holds bit `k` of every byte (bit 0 least significant), for inputs and outputs alike. +//! The Boyar-Peralta section keeps its own signal names (`y*`, `t*`, `z*`) so it can be diffed +//! against the AES and SM4 crates; its inputs are bound from the generated top layer, so its +//! `U0`-is-MSB convention never appears here. + +use crate::LANES; +use crate::bitslice::{Planes, ortho}; + +// The position masks.

From 0c9a0e002a0f08b4bb25c3c77c1c057e0b4e2b07 Mon Sep 17 00:00:00 2001 From: David Hook Date: Mon, 21 Sep 2026 09:03:31 +1000 Subject: [PATCH 07/37] camellia: add the Camellia_CFB_*, Camellia_CFB8_* and Camellia_CTR_* aliases and their camellia{128,192,256}-{cfb,cfb8,ctr} CLI commands, so Camellia covers the same four modes AES does rather than CBC alone -- `bouncycastle-modes` is cipher-agnostic and its Cfb, Cfb8 and Ctr already work over any ElectronicCodeBook, so each alias is one line of type plus the const parameters Camellia fills in (16/24/32-byte keys, a 16-byte block, and a 12-byte CTR nonce leaving the 4-byte counter the mode caps at, the same split bouncycastle-aes chooses for its 16-byte block). RFC 3713 specifies only the permutation and assigns identifiers for CBC (Sec 3), so each of the three new modes is pinned against the best published source there is, and the three sources need different handling. CFB128: the CAMELLIA-*-CFB entries of OpenSSL's evpciph_camellia.txt (3.6.2) chain into one four-block message per key length under the IV 000102..0f, over SP 800-38A Appendix F's plaintext and keys, and are straight known-answer tests through the aliases, driven under the vector's own IV via a FixedSeedRNG exactly as the existing CBC vectors are. CTR: RFC 5528's nine Camellia-CTR vectors build the counter block as a 4-octet nonce, an 8-octet IV and a block counter starting at one, which is the IPsec convention and not one the nonce/counter split can produce, so those vectors pin a reference CTR written from the SP 800-38A Sec 6.5 equations over the permutation and the aliases are then required to agree with that reference on the counter blocks they do produce; the CTR docs and the camellia*-ctr help both say ciphertexts do not interoperate with an RFC 5528 implementation. CFB8: there is no published vector -- the OpenSSL file says in as many words that it does not carry CFB{1,8}-CAMELLIAxxx -- so the aliases are held to the Sec 6.3 equations at s = 8 evaluated over the permutation. stream_mode_alias_tests.rs covers the wiring the vectors do not: that each of the nine aliases names the mode it claims to, round-trips at any length with no padding, gives the same answer whatever the chunking, draws fresh init data per encryption, and that CFB128, CFB8 and CTR are mutually distinct. The nine CLI commands are thin dispatchers over the existing stream_mode_cmd plumbing, so they inherit the IV-in-the-ciphertext convention, the 1 KiB streaming chunk and the key loader unchanged; their tests pin the OpenSSL CFB vectors end to end through the pipe and hold camellia*-cfb8 and camellia*-ctr to the library for the two modes without usable vectors. No new mutants: `cargo mutants -p bouncycastle-camellia --list` reports the same 550 before and after, because the three new source files are type aliases and documentation with no executable code of their own. quality_stats.sh's "unwraps in core code" for camellia goes 0 -> 44, all of it `.unwrap()` inside the new doctests, which the script counts from src/ without distinguishing doc comments; the doctests are written in the same style as crypto/aes/src/{cfb,cfb8,ctr}.rs, which is why aes reports 58.

The assertion the test actually makes -- non-zero status, and the algorithm named in stderr -- is unaffected, because `wait_with_output` still returns both, so the fix is to match on the write result and ignore `ErrorKind::BrokenPipe` while still panicking on every other write error. That is the same treatment, and the same reasoning, that aes_ctr_cli_tests.rs already documents for its threaded harness; the harness is copied per file, so all three new suites (cfb, cfb8, ctr) get it. Because the race is timing-dependent, camellia_cfb8_cli_tests.rs also gains a deterministic guard: a 4 MiB payload to `camellia128-cfb8` with a rejected key cannot fit in a pipe buffer, so the write is certain to get EPIPE rather than merely likely to. No behaviour outside the test harness changes.

This file predates the stream modes and has never failed CI, but the defect is identical and was demonstrated here rather than assumed: dropping a 4 MiB error-path payload into the unpatched harness reproduces exactly the panic that failed the Rust Tests workflow on the cfb8 suite. The write result is now matched on, `ErrorKind::BrokenPipe` ignored and every other write error still a panic, which is what the five aes_*_cli_tests.rs suites have always done; an audit of cli/tests confirms no suite in the tree still `.expect()`s that write. The new `a_large_payload_on_an_error_path_does_not_break_the_harness` is the deterministic guard for it -- a payload that cannot fit in a pipe buffer makes EPIPE certain rather than merely likely, so the harness cannot silently regress to the flaky form. Also reflows the over-width comment lines this series left in camellia_cfb8_cli_tests.rs: rustfmt does not wrap comments, so they passed `cargo fmt --check` while sitting past the 100-column max_width every other comment in the tree respects. Nothing the existing tests assert on changes: `wait_with_output` still returns the exit status and the stderr they match against, and no non-test code is touched.

everything else is the path in use lines and doc links. No logic change, no mutation run owed.

-> CamelliaInternal

with Camellia128Internal, Camellia192Internal and Camellia256Internal for the three key lengths, Clone, each implementing ElectronicCodeBook (new) and BlockPermutation (the block methods) separately, and ModeNames for all nine modes, since Camellia has published modes beyond the four aliased here (RFC 5528 CTR and CCM, RFC 6367 GCM). CamelliaKey>> mirrors AESKey: the key holds the mode's key state, FromKeyMaterial<16> / <24> / <32> build it per key length, and the role impls -- symmetric, block, ECB, AEAD and MAC pairs -- forward to the mode traits, so which roles a key carries is decided by its mode. Camellia128Key and friends name the key lengths. The crate aliases CBC, CFB, CFB8 and CTR as before, now with the key-state lifetime (Camellia_CBC_128<'k, Dir, Pad>, ...); the other modes are reached by naming them, and GCM is exercised through the AEAD framework. Tests: cbc_alias_tests and stream_mode_alias_tests become padded_alias_tests, alg_name_tests and a key-side stream_mode_alias_tests; mode_key_tests runs the FromKeyMaterial, block, symmetric, stream and AEAD frameworks over the keys; the OpenSSL CBC and CFB128 vectors, the RFC 5528 CTR reference, the CFB8 equations and Wycheproof drive the keys, and the RFC 3713, NTT CRYPTREC, bc-java and reference suites the engines. CLI: the twelve camellia commands load a Camellia*Key and keep their contract -- whole blocks under NoPadding for CBC, the IV or nonce in band, no --iv -- and their integration tests replay the OpenSSL vectors through the binary and check the stream commands against the keys' in-place decryption.

They were there for parity with AESKey only. The symmetric and block pairs remain; between them they cover CBC, CFB, CFB8 and CTR, the four modes the Camellia_* aliases name, and a key under any other mode has no role. mode_key_tests drops the ECB and GCM construction and framework runs. ModeNames keeps all nine names, since the mode types over the engine name themselves by them.

CamelliaKey's three constructors carried as_cipher_key and a `_ =>` arm for MAC-mode keys, which lost their role in 922236e7; both go, and with them check_key_type, since the permutation's own validation is the same check for every mode that has a role (a scoped `cargo mutants` on key.rs is 0 missed; the crate lists 577 mutants). The key docs name ECB among the symmetric-pair modes. The Security Considerations heading takes the style guide's form and the anchor follows it. The Memory Usage section tabulates the measured stack per entry point and key length: bench_camellia_mem_usage takes the AES bench's measure-closure shape for new and the six block entry points at each key length, and the figures are the closure frames from the release build's frame-layout remarks plus the return address. The three unit tests in hazmat/camellia.rs that tested public behaviour only (the engine sizes, the algorithm names, the LANES constant) move to alg_name_tests or go; the Sec 2.3.3 subkey-swap pin stays. Nits: the manifest comment, the sm4 citation in bitslice.rs, the ElectronicCodeBook attributions for methods that are on BlockPermutation, "An Camellia", and every doc or comment line past 100 columns, including the two rustfmt could not fit.

The three CBC commands are now CBC over the same block-mode helpers; the nine stream commands take --iv/--iv-file through load_iv as the aes ones do; and all twelve take the direction as -d/--direction, which every other cipher command already does. The CLI tests pin encryption as well as decryption now that the IV can be supplied: camellia*-cbc encrypt --iv reproduces the OpenSSL evpciph_camellia CBC chains followed by the PKCS7 block (computed from the permutation of the key's length), camellia*-cfb encrypt --iv reproduces the CFB chains exactly, and camellia128-cfb8 and -ctr under --iv are held to the library. The alignment test becomes an any-length test plus a rejected unpadded ciphertext. Their module docs cite the files that exist.

the four-mode scope left it unrun. It runs now the way the AES CCM suite does, over the hazmat mode traits and the permutation directly, since the keys carry no AEAD role: 486 of the 552 cases are within SP 800-38C A.1's nonce and tag sets at the three key lengths (405 valid, 81 invalid) and the other 66 are counted as unsupported. All pass. The crate docs' provenance list names both Wycheproof files.

The Camellia-192 and -256 engine constructors list their error cases as the Camellia-128 one does, instead of pointing at ElectronicCodeBook::new; the three CRYPTREC vector arrays are static rather than const; the two index loops in the test reference engine iterate; and check_chain's explicit lifetime, which named no worker, is elided. Clippy on the crate is clean. Scoped mutants on schedule.rs: 117 tested, 114 caught, 2 unviable, 1 missed, the documented | / ^ equivalence in join.

The cbc, cfb, cfb8, ctr and key modules are private, so the docs each carried never rendered; they now sit on `Camellia_CBC_128`, `Camellia_CFB_128`, `Camellia_CFB8_128`, `Camellia_CTR_128` and `CamelliaKey`, the one path each has, and the module headers say so. The CAMELLIA-CBC-PKCS5 suite found its file through its own two candidate paths and skipped silently when neither resolved, accepted any error for an invalid case, and could not tell a zeroized output buffer from one never written; it is now the AES suite over the Camellia keys -- the shared `wycheproof_json` loader, the expected error read off the case's flags, a pre-filled output buffer that a failed decrypt must leave all zeros -- as `cbc_wycheproof.rs`, named as the suites it copies. And no test reached `Ctr`'s counter limit through a Camellia key: stream_mode_tests now does, under `CTR<15>`, where the 256th block is the last and the byte after it is refused.

The rebase onto the branch's new history (key-rework-memory rebased onto release/0.1.3alpha, which carries feature/key-rework as one squash commit) dropped those merges; this commit restores the affected files to the branch's pre-rebase tip, so the tree is identical to it.
