Certificate Status

Online Certificate Status protocol (OCSP)

Online Certificate Status Protocol (OCSP) is a set of rules and standards that enable users and applications to determine the status (valid, revoked, suspended, expired, or unknown) of a specific certificate in real time.

Certificate Revocation Lists (CRL)

The Certificate Revocation Lists (CRL) include information about revoked certificates. CRLs are cumulative and include information about all the certificates that are revoked at the moment. Certificates that are declared as not valid remain in the CRL at least until they expire.
