Associate a certificate with a contact
If you have a contact that is not associated with a certificate, or you want to change the certificate associated with a
contact, follow these steps. A contact must have at least one valid certificate to exchange encrypted PDFs.
1 Do one of the following:
• In Acrobat, choose Tools > Sign & Certify > More Sign & Certify > Manage Trusted Identities.
• In Reader, choose Edit > Protection > Manage Trusted Identities.
Note: If you don’t see the Sign & Certify or Protection panel, see the instructions for adding panels at “Task panes” on
page 9.
2 Select the contact, and click Details.
3 Click Associate Certificate.
4 Select a certificate, and click OK. Click OK again.
Verify information on a certificate
The Certificate Viewer dialog box provides user attributes and other information about a certificate. When others
import your certificate, they often want to check your fingerprint information against the information they receive with
the certificate. (The fingerprint refers to the MD5 digest and SHA1 digest values.) You can check certificate
information for your digital ID files or the ID files that you import.
For more information about verifying certificates, see the Digital Signatures User Guide (PDF) at
www.adobe.com/go/learn_acr_security_en.
The Certificate Viewer dialog box provides the following information:
• Certificate validation period
• Intended use of the certificate
• Certificate data, such as the serial number and public key method
You can also check if the certificate authority has revoked the certificate. Certificates are typically revoked when an
employee leaves the company or when security is compromised in some way.
