Verify signatures on a PDF

When to use

Use verification when you receive a signed PDF from outside and need to know whether the signature is genuine, or when you want to re-check a file signed through XBuddy.

Before you start

  • You need signatures:read to open /signatures/verify.
  • Full verification applies to PAdES signatures, including a revocation check. For other signed PDFs the screen only reports that a signature is present.

Open the verify screen

Go to E-Signatures → Verify signatures.

Upload the PDF

Choose the PDF file you want to check.

Read the result

Review each signature found and whether it was verified.

Tips & common mistakes

  • “Signature present” is not the same as “verified”: only PAdES signatures are fully verified.
  • Verify the original file; editing or re-saving a signed PDF can break its signatures.
  • Keep the verification result with the file when you archive it.
