Certificate Revocation List
Certificates will appear on our CRL within 24 hours after they have been revoked. Revoked certificates are no longer trusted for a variety of reasons (for example, the password that protects the corresponding private key has been compromised).
You should not establish a secure session with a Web site that is using a revoked certificate.
For Code Signing certificates, you should not accept or execute signed content if the associated certificate has been revoked or has expired. When downloading or otherwise installing signed content, applications generally allow you to view the certificate associated with the signed application as part of the download or install process.
