Worked on the Cosmian/kms repository to enhance cryptographic signing and verification workflows using Rust, focusing on RFC 6979-compliant operations for both raw and digest data. Implemented support for the K256 elliptic curve alongside P-256, ensuring cross-curve compatibility and improved interoperability. Addressed edge-case bugs in sign/verify logic, particularly for RSASSA-PSS, by refining error handling and padding mechanisms. Expanded automated test coverage to validate new features and edge cases, contributing to greater reliability and auditability. Updated dependencies and maintained clear commit traceability, demonstrating a methodical approach to backend development, cryptography, and robust testing practices throughout the project.

Jan 1, 2026Summary for 2026-01: Key features delivered: K256 RFC6979 support for sign/verify on non-FIPS builds; ensured cross-curve compatibility with P-256; dependencies updated; expanded testing. Major bugs fixed: RSASSA-PSS raw vs digest handling fixed; improved error handling and padding settings; added tests. Overall impact and accomplishments: Extended cryptographic capabilities, increased reliability and correctness of signing workflows, improved cross-curve interoperability, and strengthened test coverage. Technologies/skills demonstrated: ECC (K256, P-256), RSASSA-PSS, RFC6979, dependency management, test automation, robust error handling, and commit traceability (commits #671, #677).
