/ Certificate register

Verify a certificate.

Enter the certificate number printed on the document, or upload the copy you were sent, to confirm it is genuine and current.

01 — By number

Verify by certificate number

02 — By file

Check a PDF you were sent

Upload the PDF you received. We compare its SHA-256 fingerprint with the certified copy we issued, check whether it carries a digital signature, and show the certificate's current status. The file is hashed in memory and not stored.

Each certificate on this register is recorded with a SHA-256 fingerprint of the original file as received from the issuer. A fingerprint changes if even one byte of the file is altered. The live register shows current status even if an old PDF still looks genuine.
