Verify a ToroDocs document

Upload the sealed PDF to check its authenticity, or enter the verification code printed on the Certificate of Completion page.

Verify by uploading the PDF

We compute the SHA-256 fingerprint of your file and compare it to the sealed record. Any modification — even a single byte — produces a different fingerprint and fails verification.

Verify by code

Enter the UUID verification code from the Certificate of Completion page or the document footer.

The embedded PKCS#7 digital signature additionally lets any PDF reader (Adobe Acrobat, macOS Preview, etc.) verify document integrity without uploading anywhere. A self-signed certificate means readers show "valid, signer not trusted" — this is expected and correct; the signature still confirms unaltered content since sealing.
