ECTA s15 record verification

Check the hash, not the letterhead.

Every evidence pack, certificate and daily seal carries a SHA-256 hash. Paste it below to check whether it resolves to a sealed artefact and whether the audit chain still verifies.

Verify a hash

Find the hash on the certificate footer, the evidence pack manifest, the printed QR code or the audit log entry.
