During June 2026, this developer enhanced the zotonic/zotonic repository by implementing SHA-256-based media file integrity verification. They migrated the database schema from a legacy SHA-1 column to a dedicated digest column, adopting PostgreSQL’s bytea type for efficient storage and compatibility. Using Erlang and SQL, they enabled automatic hash calculation during file processing and exposed the checksum in the admin interface, improving auditability and security for media assets. Additionally, they addressed a template engine issue to ensure reliable checksum display in the admin media view. Their work delivered end-to-end integrity verification, reducing the risk of media tampering and data loss.
