Pqc tls support for portals and apis - #3296
Conversation
📝 WalkthroughWalkthroughThe change adds configurable TLS versions, cipher suites, ECDH curves, certificates, and mutual-TLS identity authorization across gateway, runtime, platform, and portal services. It also adds optional TLS listeners, PQC fallback configuration, and conditional SDS-over-ADS behavior. ChangesHTTPS TLS configuration
Gateway xDS mutual TLS

Conditional SDS over ADS
PQC fallback policy
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔴 Critical · up to This change adds post-quantum TLS and mutual TLS across gateway and portal services, but the current implementation can ship reusable private keys, fail policy synchronization, silently expose the admin API over plaintext, and miss the intended hybrid negotiation. Newly added tests also have compilation errors, so the PR is not merge-ready and should be blocked until these issues are corrected. Possibly related PRs

- Line 23: Resolve the contradiction between the standalone-X25519 prohibition
and the fallback behavior described in directive 3 and its example. Either
explicitly define standalone X25519 as a configuration-gated legacy fallback
with a tracked migration issue, or remove the X25519-only fallback example and
references; ensure the guidance for absent or disabled PQC is consistent
throughout the document.
- Line 23: Update the hybrid PQC guidance near the TLS curve configuration to
replace the incorrect “RFC 9180 pattern” reference with RFC 10024 under the RFC
9954 framework, while retaining RFC 9180 only where HPKE or the
application-level combiner is being described.
- Line 23: Update the TLS guidance around ecdhCurve and the hybrid
X25519MLKEM768 group to require OpenSSL 3.5+ or official Node.js 22.20.0+
builds, and add an effective-runtime capability check before configuring the
hybrid group; retain X25519 as the classical fallback when the capability is
unavailable.
- Around line 51-52: Update the fallback branch guarded by config.pqcEnabled and
recipientPqcPub so an absent recipientPqcPub is accepted only when authenticated
capability negotiation or explicit local policy authorizes downgrade; otherwise
fail closed instead of returning the X25519-only sharedSecret. Add a test
covering removal of the PQC advertisement and verifying the downgrade is
rejected.
- Line 7: Extend the PQC guidance to cover portals/api-portal and other affected
Node.js TLS services, including the TLS listener using tlsOptions.js and
X25519MLKEM768. Ensure the rule applies the same optional-but-supported posture

Directive 1 prohibits standalone X25519. Directive 3 and the example return an X25519-only secret when PQC is disabled or recipientPqcPub is absent. Explicitly allow this only as a configuration-gated legacy fallback with a tracked migration issue, or remove the fallback example.

RFC 10024 RFC 9954 X25519MLKEM768 RFC 9180 hybrid TLS group
💡 Result:
As of August 24, 2026, the relevant standards and technical details for hybrid TLS key exchange using ML-KEM are as follows: RFC 10024, published in August 2026, defines post-quantum traditional (PQ/T) hybrid key agreement mechanisms for TLS 1.3 [1][2]. This standard introduces three new supported groups that combine the post-quantum algorithm ML-KEM (Module-Lattice-Based Key Encapsulation Mechanism) with ephemeral Elliptic Curve Diffie-Hellman (ECDHE) [1][3]: - X25519MLKEM768 - SecP256r1MLKEM768 - SecP384r1MLKEM1024 These groups follow the construction principles defined in RFC 9954 [1][3]. RFC 9954, published in July 2026, provides an informational framework for constructing hybrid key exchanges in TLS 1.3 [4][5]. It utilizes a simple concatenation-based approach where the shared secrets and protocol messages from the component algorithms (e.g., ECDHE and ML-KEM) are concatenated to form a single key exchange mechanism, allowing them to be negotiated and transmitted using existing TLS 1.3 structures [4][6]. For the X25519MLKEM768 hybrid group, the shared secret is formed by concatenating the ML-KEM-768 shared secret and the X25519 shared secret [7][8]. While X25519 is not itself a FIPS-approved algorithm, the combination is generally considered compliant with FIPS 140-3 requirements because ML-KEM is FIPS-approved [7]. In practice, X25519MLKEM768 has become a standard approach for deploying post-quantum hybrid key exchange, supported by major TLS stacks including OpenSSL 3.5+, BoringSSL, and various Go-based implementations [9].

💡 Result:
RFC 10024 and RFC 9954 are technical documents related to hybrid key exchange in the Transport Layer Security (TLS) protocol version 1.3 [1][2]. RFC 9954: Hybrid Key Exchange in TLS 1.3 This informational RFC, published in July 2026, defines a framework for combining traditional key exchange algorithms (such as ECDHE using Curve25519 or NIST curves) with next-generation algorithms (such as post-quantum KEMs) in TLS 1.3 [2][3]. The design employs a simple concatenation-based approach, where the key exchange messages from multiple algorithms are concatenated and transmitted as a single value to avoid modifying existing TLS 1.3 data structures [3][4]. RFC 10024: Post-Quantum Traditional (PQ/T) Hybrid Key Agreement Mechanisms for TLS 1.3 This document, published in August 2026, applies the framework established in RFC 9954 to specific post-quantum algorithms [1][5]. It introduces three hybrid key agreement mechanisms that combine the post-quantum ML-KEM (Module-Lattice-Based Key Encapsulation Mechanism) with ECDHE [1]: - X25519MLKEM768: Combines X25519 with ML-KEM-768 [1][6]. - SecP256r1MLKEM768: Combines SecP256r1 (NIST P-256) with ML-KEM-768 [1][6]. - SecP384r1MLKEM1024: Combines SecP384r1 (NIST P-384) with ML-KEM-1024 [1][6]. For X25519MLKEM768 specifically, the client key exchange value is the concatenation of the ML-KEM-768 encapsulation key and the X25519 ephemeral share, resulting in a total client share size of 1216 bytes [1][7]. The assigned identifier for X25519MLKEM768 is 4588 (0x11EC) [6][7].

OpenSSL official documentation X25519MLKEM768 supported version TLS group OpenSSL 3.5
💡 Result:
OpenSSL 3.5 introduced full support for the hybrid X25519MLKEM768 TLS group [1][2][3]. Key details regarding this support include: - Default Inclusion: Starting with OpenSSL 3.5, X25519MLKEM768 is included in the default TLS supported groups list and is preferred by default for TLS 1.3 keyshares [2][3][4][5]. - Functionality: It is a hybrid key exchange mechanism combining classical X25519 with the post-quantum ML-KEM-768 (as defined in FIPS 203) [3][6]. It is specifically documented as a post-quantum traditional (PQ/T) hybrid key agreement mechanism under RFC 10024 [6]. - Configuration: When configuring applications to use this group, users are advised to use SSL_set1_groups_list rather than SSL_set1_groups, as the latter may not accept it directly in all contexts [7]. - Compliance: Although X25519 is not itself a FIPS-approved algorithm, this hybrid combination is permitted in FIPS 140-3 contexts because the ML-KEM component is FIPS-approved [1]. In addition to X25519MLKEM768, OpenSSL 3.5 also introduced support for two other hybrid groups: SecP256r1MLKEM768 and SecP384r1MLKEM1024 [2][3].

Node.js official release documentation Node.js 22 OpenSSL 3.0 3.5.2 versions
💡 Result:
Node.js 22 (codenamed Jod) bundles OpenSSL 3.5.x as part of its official release distributions [1][2]. While Node.js 22 initially launched with OpenSSL 3.0.x, the project updated the bundled OpenSSL version to 3.5.2 in Node.js v22.20.0 to ensure continued support for the release line, as the original OpenSSL 3.0.x reached its end-of-support in September 2026 [1][2]. As of August 24, 2026, Node.js 22.x releases have been further updated to include even newer versions, such as OpenSSL 3.5.7, to maintain security and stability [3]. These updates apply to official Node.js binaries and builds using the default configuration [1][2]. They do not affect third-party builds of Node.js that are dynamically linked against an external OpenSSL library [1][2]. Node.js 22 is scheduled for End-of-Life on April 30, 2027 [1][4][5].

💡 Result:
X25519MLKEM768 is a hybrid post-quantum key exchange group introduced in OpenSSL 3.5 [1][2][3]. It combines the classical X25519 elliptic curve key exchange with the post-quantum ML-KEM-768 (Module-Lattice-Based Key-Encapsulation Mechanism) algorithm, as specified in FIPS 203 [4][3]. Key characteristics of X25519MLKEM768 include: - Hybrid Security: By deriving a session secret from both X25519 and ML-KEM-768, the key agreement remains secure as long as either of the underlying algorithms remains unbroken [4]. - FIPS Compliance: Although X25519 itself is not a FIPS-approved algorithm, the hybrid combination is permitted in FIPS 140-3 environments because ML-KEM is FIPS-approved [4]. - Default Usage: Starting with OpenSSL 3.5, X25519MLKEM768 is included in the default TLS group list and is often prioritized as a default keyshare [1][3]. - Implementation Details: The shared secret is formed by concatenating the 32-byte shared secret from ML-KEM-768 followed by the 32-byte shared secret from X25519 [4]. Public and private keys for this group consist of the ML-KEM component followed by the X25519 component [4]. - Performance: It offers CPU performance comparable to classical ECDH groups like X25519, though it requires significantly larger key exchange messages [1][3]. In OpenSSL 3.5 and later, a new configuration syntax for TLS 1.3 servers allows for the partitioning of groups into security-equivalent tuples to ensure optimal group negotiation, which helps prevent issues where clients might otherwise fail to negotiate this preferred quantum-resistant group [5]. Node.js versions utilizing OpenSSL 3.5.2 or later (such as Node.js 22.20.0) include support for these capabilities [6].

Bind recipientPqcPub to authenticated capability negotiation.
When config.pqcEnabled is true and recipientPqcPub is absent, this branch returns an X25519-only secret. If the value comes from an unauthenticated peer advertisement, an active intermediary can remove it and force a downgrade. Require authenticated negotiation or explicit local policy before allowing fallback. Otherwise, fail closed. Add a downgrade test.

Make the hybrid group the preferred curve in every shipped TLS configuration. The current defaults and compose/config values put X25519MLKEM768 after classical groups or omit it, so deployments that enable this feature can still negotiate classical-only TLS by preference. Set the hybrid group first, preserve classical fallback only where compatibility requires it, and keep the Go listener defaults and configuration templates consistent with those values.

Align the policy xDS TLS settings before enabling the client.
gateway/configs/config.toml omits controller.policy_server.tls, so the server defaults to plaintext with X25519,P-256. This compose file enables policy-engine mTLS and offers only X25519MLKEM768, so the connection fails. Configure the server with matching certificates and client identity, then set the client list to X25519MLKEM768,X25519,P-256. Add the hybrid group to the server list if hybrid negotiation is required.

The SDS gating predicate covers only one of the two ways a cluster attaches TLS. ClusterResourcesReferenceUpstreamCASecret inspects Cluster.TransportSocketMatches and ignores Cluster.TransportSocket. Envoy accepts an UpstreamTlsContext on either field. When a cluster uses the single TransportSocket field and names SecretNameUpstreamCA, the predicate returns false, the snapshot omits the Secret resource, and Envoy keeps the cluster in warming because the secret it watches never arrives. The previous unconditional injection hid this case.

Fail closed when the admin TLS listener cannot start.
Two paths drop the TLS listener without stopping the process:
- Line 86 logs a build error and leaves
tlsServernil. - Line 142 logs a
ListenAndServeTLSerror inside a goroutine. A missing or unreadable certificate file, or a port already in use, reaches this path at runtime.
In both cases the operator set admin.tls.enabled = true, but the process continues serving the admin API on the plaintext port only. The failure is visible only in a log line. Return the error from NewServer, or propagate the listener error so Start fails.
🔒 Proposed fail-closed handling in `Start`

if s.tlsServer != nil {

+ tlsErrCh <- fmt.Errorf("admin TLS server error: %w", err)
}

}Then select on tlsErrCh alongside the plaintext listener result and return the first error.

Do not ship private keys in the distribution zip.
Lines 243, 246, 248, and 250 copy default-listener.key, server.key, envoy-client.key, and policy-engine-client.key into $(DIST_DIR)/resources. Every download of the distribution then carries identical private key material. gateway/configs/config.toml enables controller.server.tls with the shipped listener key, and gateway/distribution/docker-compose.yaml mounts resources/xds-certs into both containers with POLICY_ENGINE_XDS_TLS_ENABLED=true. Any holder of the zip can present policy-engine-client.crt and pass the allowed_client_identities check on the policy xDS server, which distributes API-key hashes, subscription state, and full policy chains. The shared server.key also allows impersonation of the controller TLS listener.
Generate the key material during scripts/setup.sh, or require the operator to supply it and fail startup when it is absent. If a demo profile needs pre-generated keys, keep them out of the released artifact and out of any default-enabled configuration.
As per coding guidelines: "Packaged configuration must never ship functional default credentials; credentials must be generated or explicitly configured, stored only as hashes with restrictive permissions, and reloaded on restart" (GO-AUTH-014), which the packaged config.toml and docker-compose.yaml consume here.

In `@gateway/Makefile` around lines 241 - 250, Remove the private-key copy steps
from the distribution packaging target, including default-listener.key,
server.key, envoy-client.key, and policy-engine-client.key. Update the
setup/startup flow around scripts/setup.sh and the packaged TLS configuration so
keys are generated during setup or explicitly supplied by the operator, with
startup failing when required keys are absent; ensure demo credentials are
neither included in released artifacts nor enabled by default.
