Mar 1, 2026March 2026 highlights FEGA-Norway: Implemented enhanced mock AMQP routing with alternate exchanges and clearer fanout/topic behaviors, improving test realism. Added JSON schema validation to the mq-interceptor (JSONValidator, schema import/validation) with a refactor of error forwarding, alongside expanded unit and end-to-end tests and updated docs. These changes increased test fidelity, reduced debugging time, and strengthen the quality gates before production for MQ-driven features.

Dec 1, 2024December 2024 – FEGA-Norway (ELIXIR-NO). No new user-facing features delivered. Major bug fixed: PBKDF2 Key Length Unit Correction, ensuring KEY_LENGTH is interpreted in bits for PBEKeySpec, preventing incorrect key lengths and aligning derivation with PBKDF2 specifications. Impact: strengthens cryptographic correctness, reduces risk of key-length related vulnerabilities, and improves security posture of authentication workflows. Technologies/skills demonstrated: cryptography API usage (PBEKeySpec), careful unit handling, and commit-based traceability.
