Verify a certificate of authenticity

Number not found in this registry

This number is not in the Obscura Flow registry. That says neither that the certificate is genuine nor that it is forged: this page cannot conclude anything from it.

• Check the number and version exactly as printed on the document: one letter or digit changes the address.
• Verify the PDF file below: that check runs offline and does not depend on the registry.
• The certificate may have been issued without being published to the registry, or by another issuer: ask the seller or the author.

Verification not possible

This file is not a PDF. Choose the certificate's PDF file, not a photograph or a scan of the printed document.

This PDF contains no signed Obscura Flow certificate.

This certificate was issued before verification data was added: its file cannot be checked here. The registry remains the only source for this number.

The issuer's public key could not be retrieved. Try again later: the file itself is not at fault.

Verification interrupted

Verification could not complete in this browser. Try again, ideally from an up-to-date browser.
