7.5.1.4 Checking Certificate Revocation Status

Only the certificate issuer (a certificate authority) has the right to revoke a certificate. A certificate could be
revoked because its security might be compromised, it could be invalid for some reason, or the owner of
the ID might have left the company. Adobe applications check revocation status as part of its public key
authentication.
To check a certificate's revocation status:
1. Choose the Certificate Viewer's Revocation tab.
2. Choose Check Revocation.
The button is only active if revocation checking has not occurred and it is possible to do a check.
Revocation checking is not possible for trusted roots and self-signed certificates.
3. Choose OK.
