CRLs
CRLs are only necessary if using Certificates.
CRL (Certificate Revocation List) files show Certificates which have been revoked, and are no
longer valid. Each CA issues their own CRLs.
It is VERY IMPORTANT to keep your CRLs up-to-date. You need to obtain the CRL for each
CA regularly. The "Next Update" field in the CRL shows when the next update will be avail-
