How this check works

How this check works

  1. You enter the ID

    Printed on the certificate and on the lot paperwork. Nothing to sign up for — the check is open to anyone holding one.

  2. The seal is recomputed

    We take the stored record and recompute its SHA-256 from scratch. A stored “valid” flag is never trusted — if one character of the contents changed, the recomputed hash no longer matches.

  3. The chain is walked

    Every certificate commits to the one before it, so altering an old record breaks that record and every certificate issued after it. That is what makes the register tamper-evident rather than merely a list.

If a certificate does not verify, do not treat the paperwork as authoritative — ask the issuer to re-issue it from the register.
