Certificate verification
Check a certificate.
Enter the ID printed on the document. A genuine certificate returns the holder, the title and the date it was issued - straight from our registry.

The registry is encrypted
Every record is sealed with a key derived from its own certificate ID. Downloading the registry file tells you how many certificates exist and nothing else.
Checks run in your browser
The ID you type is never sent anywhere. It is used locally to unseal the matching record, so we never see who is checking what.
Guessing is expensive
Every ID ends in six random characters, and each attempt costs a deliberate 310,000-round key derivation. Working through the possibilities would take years of computing per certificate.
