How verification works
01
Lookup
The certificate ID is matched against the TESSERA Registry database to retrieve the full certification record and associated metadata.
02
Signature check
The ECDSA P-256 cryptographic signature is verified against the registry’s public key to ensure data integrity and authenticity.
03
Status & OCSP
The certificate’s validity period and revocation status are checked in real-time via the registry’s OCSP-equivalent endpoint.
