Checking certificates for revocation excludes the possibility that an application or user
will accept credentials that have been revoked by a Certification Authority administrator. A
certificate is considered valid until its expiration date. However, various circumstances may
cause a certificate to become invalid prior to the expiration of the validity period. Such
circumstances include change of name, change of association between subject and Certification
Authority and compromise or suspected compromise of the corresponding private key. Under such
circumstances, the issuing Certification Authority needs to revoke the certificate. In order
to get the revocation status of a certificate, open the certificate (click on
Menu File > Open > Open Certificate) and click on
Get Revocation Status button.
When checking the revocation status of a certificate, the following situations may be found:
The certificate has been revoked;
The certificate has not been revoked;
No revocation information found;
Invalid revocation information found;
An error was encountered while trying to retrieve the revocation status of the certificate.
