Add a certificate from a digital signature in a PDF
You can safely add a certificate to your trusted identities from a signed PDF by first verifying the fingerprint with the
originator or the certificate.
1 Open the PDF containing the self-signed signature.
2 Open the signature panel, and select the certificate in the Signatures panel.
3 On the Options menu, click Show Signature Properties, and then click Show Certificate.
4 If the certificate is self-signed, contact the originator of the certificate to confirm that the fingerprint values on the
Details tab are correct. Trust the certificate only if the values match the values of the originator.
5 Click the Trust tab, click Add To Trusted Identities, and click OK.
