When do Certificates and CRLs Expire?
Self-signed certificates are valid for five years. The expiration date for third-party certificates varies, depending
on who issued the certificate; contact the CA for more information. A Certificate Revocation List (CRL) is valid for
a much shorter period of time: days, or even hours.
When using certificates and CRLs, it is important for the clock on the appliance to be accurate, since it is used to
determine when these items expire.
