What is a certification revocation list (CRL)?
A certificate revocation list is a list compiled and maintained by the certification authority of all the digital certificates it has issued that that are no longer valid. However, the CRL does not include digital certificates that have expired. Any party wanting to rely on a digital certificate should check the CRL to determine whether that digital certificate has been revoked. digital certificates are revoked, for example, when they are lost, stolen or if an employee who had been issued with one had left the company.
