chore(deps): Bump aws-lc-rs from 1.17.3 to 1.18.0

[dependabot]

Bumps aws-lc-rs from 1.17.3 to 1.18.0.

Release notes

Sourced from aws-lc-rs's releases.

aws-lc-rs v1.18.0

AWS-LC-FIPS module updated to 4.x

This release switches aws-lc-fips-sys (used via the fips feature) from the AWS-LC-FIPS 3.x branch to AWS-LC-FIPS 4.0.

• If your project requires FIPS compliance, please consult your local FIPS compliance experts before upgrading. The FIPS v3 module shipped in aws-lc-rs v1.17.x is FIPS 140-3 validated ([Certificate #5314](https://csrc.nist.gov/projects/cryptographic-module-validation-program/certificate/5314) static, [Certificate #5298](https://csrc.nist.gov/projects/cryptographic-module-validation-program/certificate/5298) dynamic). The 4.x module has completed validation testing by an accredited lab and has been submitted to NIST for certification. Refer to the CMVP Modules In Progress List for its current status, and to FIPS.md for security policies and supported operating environments.
• Consumers who need to remain on the FIPS 3.x module should pin aws-lc-rs to <1.18.0. See the Cargo Book on Specifying Dependencies.

What's Changed

• Switch aws-lc-fips-sys to AWS-LC's "FIPS 4.0" branch by @​justsmth in aws/aws-lc-rs#1185
  • aws-lc-fips-sys v0.13.16 -> v0.14.0. Please see the call-out above.
• The ML-DSA signature APIs are now stable 🎉 by @​justsmth in aws/aws-lc-rs#1188 and aws/aws-lc-rs#1189
  • PqdsaKeyPair, PqdsaPublicKey, PqdsaPrivateKey, PqdsaSigningAlgorithm, PqdsaVerificationAlgorithm, and the ML_DSA_44 / ML_DSA_65 / ML_DSA_87 algorithms (and their _SIGNING counterparts) now live in aws_lc_rs::signature. ML-DSA no longer requires the unstable feature, and is now available under fips -- the FIPS 4.0 module provides ML-DSA, which is what had kept these APIs unstable. See our updated API documentation.
  • Please migrate any use of aws_lc_rs::unstable::signature to aws_lc_rs::signature. The unstable::signature module remains as deprecated aliases and will be removed in a future release.
  • PqdsaKeyPair::to_pkcs8 has been renamed to to_pkcs8v1, since elsewhere in the module an unqualified to_pkcs8 means PKCS#8 v2. A deprecated to_pkcs8 alias remains available under the unstable feature.
  • Existing unstable consumers continue to compile, with deprecation warnings. Two cases need a source change: builds using #![deny(warnings)], and code that glob-imports both signature::* and unstable::signature::*, which now needs an explicit import to disambiguate.
  • Behavior change: PqdsaVerificationAlgorithm::parsed_verify_digest_sig now always returns Unspecified. Digest-then-verify is not an operation defined by FIPS 204 -- pure ML-DSA signs the message itself, and the pre-hash variant (HashML-DSA) uses a distinct domain separator that this API does not implement.
• Add out-of-place AEAD sealing by @​iainmcgin in aws/aws-lc-rs#1183
  • Adds seal_separate_out_of_place to LessSafeKey and TlsRecordSealingKey. Every sealing entry point was previously in-place, so a caller whose plaintext was borrowed or shared had to copy it into a scratch buffer purely to make it mutable. This mirrors the existing open_separate_gather, so the sealing and opening directions now match.
• Add rsa::KeyPair::from_components for constructing RSA key pairs from raw components by @​justsmth in aws/aws-lc-rs#1175
  • Adds rsa::KeyPairComponents and rsa::KeyPair::from_components, matching ring 0.17, so a signing key can be built from formats such as JWK without first encoding the components as DER. Unlike ring, d and the CRT parameters are validated at construction using RSA_check_key, so keys with inconsistent or placeholder values that ring accepts may be rejected. Unnecessary generic bounds were also removed from PublicKeyComponents.
• Automatically optimize aws-lc for size when opt-level is "s" or "z" by @​justsmth in aws/aws-lc-rs#1159
  • The builder now enables AWS-LC's size-optimized configuration (OPENSSL_SMALL, and no AVX-512 assembly on x86_64) whenever Cargo is already building for size. In CI, a small binary exercising SHA-256, AES-256-GCM, and ECDSA P-256 is 36-50% smaller at opt-level=z than at opt-level=3: 50% on x86_64 Linux, 48% on aarch64 macOS, 39% on x86_64 Windows, 36% on aarch64 Linux. Your own savings depend on how much of AWS-LC your binary retains.
  • No algorithms are removed and outputs are unchanged; the trade-off is slower elliptic-curve performance. Set AWS_LC_SYS_SMALL=1/=0 to force it on or off independently of opt-level.
  • FIPS builds do not opt in automatically: aws-lc-fips-sys requires an explicit AWS_LC_FIPS_SYS_SMALL=1, and warns when it is set.
  • Partially addresses aws/aws-lc-rs#745; the default size under opt-level=3 footprint is unchanged.
• Export native library build metadata from the -sys crates by @​justsmth in aws/aws-lc-rs#1187, including original commits from @​glebpom in aws/aws-lc-rs#1184
  • Downstream build scripts compiling C code against AWS-LC can now locate our artifacts via DEP_AWS_LC_* / DEP_AWS_LC_FIPS_* (libdir, libcrypto_path, link_kind, and libssl_path with ssl), consistently across the CC, CMake, and system-library build paths. Existing linker directives are unchanged. On Windows, the *_path values are the link-time artifact (import library), not the runtime DLL.
• Key wrap hardening by @​justsmth in aws/aws-lc-rs#1190 and aws/aws-lc-rs#1191
  • KeyEncryptionKey::unwrap no longer underflows on ciphertexts shorter than 8 bytes. Since the ciphertext is untrusted input, builds with overflow-checks = true would panic instead of returning the documented Err(Unspecified); default release builds were unaffected.
  • KeyEncryptionKey now zeroizes its key material on drop, consistent with the other key types in this crate.
• docs(signature): correct outdated note about signing a separate digest by @​WesleyRosenblum in aws/aws-lc-rs#1186

Upstream AWS-LC (v5.5.0)

aws-lc-sys v0.44.0 aligns with AWS-LC v5.5.0 (previously v5.2.0). See also the release notes for v5.3.0 and v5.4.0.

Build Improvements

• Fix bindings copy from read-only prebuilt AWS-LC install by @​justsmth in aws/aws-lc-rs#1194
  • Copies into OUT_DIR now remove any stale destination first and leave the fresh copy writable, so building against a read-only prebuilt install (e.g. the Nix store) no longer fails with Permission denied on a build-script rerun. An OUT_DIR already poisoned by an earlier build now recovers without a cargo clean.

Issues Being Closed

• ML-DSA stabilization? -- aws/aws-lc-rs#964
• Expose out-of-place AEAD sealing -- aws/aws-lc-rs#1182
