Worked on the privacyidea/privacyidea repository to enhance audit trail capabilities by enabling support for 4096-bit RSA keys. Addressed schema limitations by 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. Focused on database management and schema migration, leveraging Python and SQL to implement these changes. The work improved security auditing and compliance readiness for organizations using stronger cryptographic keys. Demonstrated a methodical approach to schema evolution and Git-based change management, delivering a targeted feature that addressed a specific business requirement without introducing new bugs.
