The certificate exists, its Ed25519 signature is valid, and it has not been revoked. To check that a specific file matches the artifact recorded in this certificate, use the Verify Your File section below.

cert.v1 certificate. The Ed25519 signature, the certified SHA-256 dataset fingerprint, the issuer, and the timestamp are all still independently verifiable on this page — no account required. What cert.v1 does not add is upload-based per-file ZIP verification; that ships in cert.v2 and newer. Any notary or dataset certified today issues cert.v2 automatically.
