Dec 1, 2025December 2025 monthly summary for cryspen/libcrux: Focused on code quality and maintainability through a targeted codebase cleanup and API exposure improvements. Implemented an import-structure refactor to avoid re-exporting from schema_common, removed unnecessary dead-code allowances, and updated tests to align with the new structure. No major bug fixes reported this month; all changes reduce namespace conflicts and streamline future refactors, enhancing reliability and onboarding.

Nov 1, 2025In November 2025 I delivered a modularized ML-KEM/ML-DSA KATs framework for cryspen/libcrux, consolidating KAT loading into a dedicated libcrux-kats crate, introducing shared ML-DSA schemas, and adding new KEM/DSA test cases. I implemented feature-flag controlled test loading to skip unsupported scenarios, improving maintainability, test coverage, and scalability of the KAT suite. The work included reorganizing the repository structure and updating tests to the latest versions, including moving existing KATs, macros, and shared utilities into common modules. I enhanced reliability by adding explicit error messages and panic traces for deserialization issues and unsupported pre-hash algorithms in signature generation/verification. Documentation and changelog coverage was expanded to reflect ACVP KATs and ML-KEM/ML-DSA usage, including README updates and a new CHANGELOG.md. These changes increase test coverage, reduce debugging time, and provide a scalable, maintainable framework for cryptographic validation tests that supports faster release cycles and clearer onboarding.

Delivered key tooling changes, CI/CD enhancements, architectural refactors, expanded testing, and build hygiene improvements with clear business value: faster feedback, reduced pipeline risk, and easier maintenance across the codebase. Key features delivered: - Build tooling and wasm path support: repurpose no-std check for wasm workflow (56b85c5cea8d2517d4befed6f928eb8416897a00) and rename no-std build script (f03f7ce91447116f2b3d2ea83b951bddca865d23); tooling naming updated across the repo (3b88d861681d460b5c1a2fdd7967aa578fc7720e). - CI/CD and workflow improvements: MLKEM workflow now supports optional workflow_dispatch input (bb636095912074f77fa63b5e2d04dc2fe6a6febb); get-hax-ref job runs unconditionally (cd76b4a2d690f282d93b2d5c2cd735f6f999d98d); workflow_dispatch inputs restored across other workflows (e3c56d0f6d0341f350b0e90c446a021c88e73398). - Documentation and inline comments: general updates and improved doc comments across modules (d8399f54f1b02488f07d403f26cc38180d519f9c; f28d692dc0c7530640ef589abd215a0f4f849f01; 69357eeb02a48a3aa0ab7a89319c31e18ecb2012). - Refactor for clarity and maintenance: move update() and reset() to DigestBase trait; rename DigestBase to DigestIncrementalBase; constants moved to trait impl (5ef8905a21a6062dd765951c8b08c9bad0219bf0; c4c96cabb4510d51a8ace8aaf29d1aa8d79900e3; a4d0cb855125e3573361149da537067039f45621). - Testing and quality improvements: added blake2 tests and generic tests; derive PartialEq on error types; improved error handling with Display/Error support (526e44c090c2722b302bb697f8e9aba91e7aa6c1; 10b1f40dbb68ffd0e3ea1c75119b7c0dd41d72f0; ea729af21514b16816ec1b7f0c5f04f91ae716fe; f235fd99b77ac9af3226a021ab23d8fe51c268dd). - Build hygiene: ensure clean workspace with cargo clean, extract secrets before SHA3, and clean SHA3 immediately before building (16966bc4530c507d361d41e0b98ab5c4c4985bd9; b357b5e3d4e3d8a8f0c8a9b9c9a9b9e9a9d9a9f; f3107d3ef41dabd54a399b4f77f7c487cf897b45). Major bugs fixed: - Removed an unnecessary debug assert and fixed whitespace formatting, improving reliability and consistency (3df4ae6da1181feb8d5785061fa9b1e56014fe0b; 7c259bcf3132541865713b6e3a9abdedbee192a1). Overall impact and accomplishments: - Smoother, more reliable build and release cycles; clearer tooling and documentation; improved test coverage and error handling; and stronger security hygiene around secrets and pre-build steps.
