Situatie
- Open the digitally signed PDF that you need to validate using Power PDF.
- Locate the digital signature object within the document.
- Right click or command-click on the signature object.
- Select “Verify Signature” from the context menu.
- Power PDF automatically checks the information behind the signature and displays a message saying “Signature Valid” if the document remains in its original form.
Repeat steps 3 and 4 as needed with any other signatures in the document. If Power PDF displays “Signature Validity Unknown,” you should proceed to verify the integrity of the document with the original signer.
Click the “Verify Identity” to check for contact information and to match signature certificate numbers. You may need to contact the signer directly for additional information.
