Verify a Pack

Check that an EU AI Act evidence pack is authentic and unchanged since it was signed. Your file never leaves your computer — all verification happens in your browser.

Why verify?

An evidence pack is signed with Ed25519, and Clause50 publishes the public key at https://clause50.com/.well-known/clause50-manifest-keys.json. This means an auditor can verify the pack without contacting Clause50 — you do not have to trust Clause50's word that the document is authentic, you can check it yourself.

Verification confirms that the document came from Clause50 and has not been altered. It does NOT confirm that the evidence is accurate, that the system complies, or that the evidence set is complete. Those are operational and legal matters, not document matters.
