Verification Evidence
Certificate record
Certificate babb3610… found (cert.v1)
Canonical signature input
Payload canonicalized with RFC 8785 JCS; the signature covers these exact bytes.
Signing key
key_id vault-hmac-2025-01 did not resolve from the published signing-key document.
Key status
Key status not resolved from the published key documents.
Signature authenticity
Signature did NOT verify — the payload was modified after signing, the signing key is revoked/unavailable, or the certificate is not genuine.
Verdict: Verification failed
Failure reason: signature_invalid
Raw check flags (API)
✗ signature_valid
✓ schema_valid
✓ not_revoked
What This Certificate Proves
This certificate proves that a synthetic dataset was generated by CertifiedData and its contents match the cryptographic fingerprints recorded at issuance time.
This certificate (cert.v1) proves signature and provenance. Artifact-level hash verification is available for certificates issued under cert.v2 and later.
The certificate does not verify statistical quality or differential privacy unless explicitly stated in the generation metadata.
