During November 2024, Muragnarokstaff developed cryptographic hashing capabilities for the questdb/questdb repository, focusing on SQL functions for MD5, SHA1, and SHA256. They implemented dedicated factories for each hash algorithm and data type combination, ensuring optimized and consistent hashing across binary, string, and varchar columns. Using Java and SQL, Muragnarokstaff integrated these functions directly into the SQL execution path, enabling secure data comparisons and enhancing data integrity checks within the database. The work demonstrated a thorough approach, covering the full engineering cycle from function definition to integration, and addressed the need for robust cryptographic workflows in SQL environments.
