Feb 1, 2025

February 2025 — Betagouv/mon-service-securise: concise monthly summary focusing on business value and technical achievements across authentication, admin governance, and security infrastructure. Key features delivered: - Supervisor Revocation Admin Features: added and propagated the ability to revoke a supervisor across admin console, repository, Postgres adapter, and supervision adapter. - Salt Security Improvements: introduced support for multiple hashing salts, and the initial salt version, plus the framework to migrate salts and verify coherence. - Encryption Architecture Enhancement: encapsulated the base encryption adapter into an object to improve modularity and encapsulation. - Hashing Enhancements: implemented hashing that uses all defined salts in the configuration. - UI/UX and copy refinements: hosting wording changes, removal of the outdated IC evolution stat banner, and UI cartouche layout tightened to a single line. - Schema tweak: increased maximum size of email_hash column in the utilisateurs table to accommodate longer values. Major bugs fixed: - User Authentication and JWT Lifecycle Stabilization: fixed user redirection logic, stopped regenerating JWT on every request, corrected cookie vs JWT expiration handling, ensured frontend handles JWT expiration, and removed obsolete session duration call.
