S. Stor developed advanced cryptographic signing and verification features for the Cosmian/kms repository, focusing on RFC 6979-compliant workflows and robust elliptic curve support. Using Rust, they implemented deterministic signing for both raw and digest data, expanded compatibility to include K256 and P-256 curves, and addressed edge-case bugs in RSASSA-PSS handling. Their work included comprehensive test automation and dependency management, ensuring correctness and reliability across cryptographic operations. By improving error handling, padding, and cross-curve interoperability, S. Stor enhanced the security and auditability of backend systems. The depth of their contributions reflects strong backend development and cryptography expertise.

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).
