During September 2025, Eisenmann enhanced the privacyidea/privacyidea repository by implementing Audit Trail support for 4096-bit RSA keys. This work involved increasing the size of the pidea_audit.signature column and updating both the migration script and ORM model to ensure seamless compatibility with larger key sizes. Using Python and SQL, Eisenmann focused on database management and schema migration, applying careful change management through Git. The update addressed compliance and security auditing requirements for organizations adopting stronger cryptographic standards. While the scope was focused on a single feature, the work demonstrated depth in schema evolution and a methodical approach to database-driven development.
