Verify signed PDFs
Inspect signatures, certificates, timestamps, revocation evidence, and document integrity.
Security teams and administrators10 minutes
Before you begin
- A signed PDF
What you will complete
- A documented verification result for a completed PDF
Run verification
- 1Open E-Signature settingsGo to Settings > E-Signature and locate the PDF verification tool.
- 2Upload the PDFUse the original completed file. A modified copy may correctly fail integrity validation.
- 3Review each signatureCheck cryptographic validity, signer, signing time, certificate chain, timestamp, and LTV evidence.
- 4Record the resultRetain the verification output with the business record when your policy requires it.
Interpret common results
- Trusted means the certificate chains to a configured trust root.
- External can be cryptographically valid without being trusted by your configured roots.
- No signature means the PDF has no supported cryptographic signature even if it contains a visual mark.
- A missing timestamp or revocation evidence affects long-term assurance but does not automatically mean the document bytes were changed.
