Independent payload verifier
Canonical payload verifier
Use original canonical bytes from an audit packet you legitimately hold. The public payload page supplies a registry-backed summary, not a canonical JSON export.
Expected fingerprint
Use the certificate fingerprint from the trust stack, a registry lookup, or a shared audit packet.
Local verification
Verification is performed locally. Payloads are not transmitted during fingerprint recomputation.
Payload JSON
Paste the exported canonical JSON exactly as received.
Upload JSON
Verification verdict
Awaiting payload
Submit a canonical payload and optional expected fingerprint to begin.
Batch payload verification
Upload multiple canonical payload JSON files, optionally map expected fingerprints by filename or file order, and generate one local batch receipt for the audit run.
Expected fingerprints
Paste filename + SHA-256 pairs, or one SHA-256 fingerprint per line in the same order as the selected files.
