What is a security certificate?

A security certificate is a data file used to check the identity, authenticity and reliability of a website or Web application as a security technique. It is used as a means to provide the security level of a website to general visitors, Internet service providers (ISPs) and Web servers.
A security certificate is also known as a digital certificate and as a Secure Socket Layer (SSL) certificate.

What is a revoked certificate?

Certificate revocation is the act of invalidating a TLS/SSL before its scheduled expiration date.
A certificate should be revoked immediately when its private key shows signs of being compromised. It should also be revoked when the domain for which it was issued is no longer operational.

Certificates that are revoked are stored on a list by the CA, called the Certificate Revocation List(CRL). When a client attempts to initiate a connection with a server, it checks for problems in the certificate, and part of this check is to ensure that the certificate is not on the CRL. The CRL contains the certificates' serial number and the revocation time.
