Summary
Resolves #637
The
checksumfunction inbackend/src/migrate.tswas using MD5 to verify migration file integrity. MD5 is cryptographically broken and must not be used for integrity verification.Changes
backend/src/migrate.tswith aMigrationRunnerclass andchecksum()helperchecksum()now usescrypto.createHash('sha256')(Node.js built-in) instead of MD5CHAR(64)columnTesting
The checksum function uses Node.js's built-in
cryptomodule — no extra dependencies required.
