Let’s take a look at our validation UI when the document is signed with a self-signed certificate: In this sample case, the first paragraph informs us of the general status of the digital signature. Next, the signer name and signing date is shown. This information always comes from the certificate itself, so you don’t have programmatic access to modify it. Following that paragraph, the integrity status of the document is displayed. In this case, the document has not been modified since it was signed, which is a good sign. Finally, the UI lets us know that the certificate used for signing was a self-signed certificate. This is not necessarily bad, but we find out about this situation with a severity level of “warning.”īelow we can see what happens if we try to validate a signature with an expired certificate. In this case, we are informed that the certificate is not valid because it has expired.

To prevent confusing our users, our default UI does not show the integrity status of a document if the certificate validation failed (that is, if the general signature status is “error”).īelow is the validation UI that is shown when the certificate is not self-signed or hasn’t expired but is not yet trusted by PSPDFKit.

Once you’ve signed a PDF document using PSPDFKit, you’ll notice that after opening it in Adobe Acrobat, you might get the following validation status.

This warning is informing you that the reader application has verified that the document has not been modified since the last time it was signed, but that the certificate is not yet trusted. You can configure the certificate as a trusted anchor in Adobe Acrobat by following the instructions provided by Adobe.Īlternatively, if the PDF is opened in a Windows environment, you can configure Adobe Acrobat to automatically trust every certificate in the Windows Certificate Store by clicking Edit > Preferences > Security > Advanced Preferences, and then checking Enable searching the Windows Certificate Store for the following operations.
