To check the validity of a digital signature in a document, follow the steps below:
Load the digitally signed file to the programme and click on Verify.
After clicking on Verify, a summary window will be displayed as follows:
ATTENTION:
if the wording “the certificate has not been verified” appears, it means that the check of the signature has not been automatically started, so it will need to be manually started by clicking on Verify. In the left column it’s possible to view the file that has been digitally signed and who has signed it.
Example: In this case the signed file is called “test.pdf.p7m” and has been signed by two users: TEST COGNOME1 and TEST NOME COGNOME2
In the right column you can find the result of the verification process and the Details of the certificate, that is:
- the type of signature and its validity
- the Certificate Authority that issued the certificate
- the holder's data
