SHA-1 File Checksum & Verifier
Compute a SHA-1 checksum (hex) and verify against an expected value — still required by many legacy media manifests and ALE/AAF workflows.
SHA-1 is cryptographically retired but remains the integrity hash baked into many media manifests, DCP/IMF asset maps and older delivery specs. For pure integrity (not security) it's still perfectly serviceable, which is why post houses keep generating it.
🔒 Files are hashed entirely in your browser — nothing is uploaded.
