Verification

Check a certificate yourself.

Every certificate is signed with GPU Cert's Ed25519 key when it is issued. Enter its number to re-check that signature against what is stored. If a single character of the result was changed after issue, the signature stops matching.

A valid signature proves the certificate came from GPU Cert and has not been edited. It does not prove the person showing it to you owns that card, so check that the hardware fingerprint matches the card you are actually being sold.

To check a signature without trusting this page at all, this is GPU Cert's public key. Verify with any Ed25519 tool.
