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 own digital ID files or for ID files that you import.

For more information about verifying certificates, see Digital Signature User Guide for Adobe Acrobat and Adobe Reader (PDF) at www.adobe.com/go/learn_acr_security_en.

The Certificate Viewer dialog box provides the following information:

• The certificate validation period

• The 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.
