The crl file extension is related to Certificate revocation list used in Windows Operating system.

Certificate Revocation List (CRL) is one of two common methods when using a public key infrastructure for maintaining access to servers in a network. The other, newer method, which has superseded CRL in some cases, is Online Certificate Status Protocol (OCSP).

The CRL is exactly what its name implies: a list of subscribers paired with digital certificate status. The list enumerates revoked certificates along with the reason(s) for revocation. The dates of certificate issue, and the entities that issued them, are also included. In addition, each list contains a proposed date for the next release. When a potential user attempts to access a server, the server allows or denies access based on the CRL entry for that particular user.

The main limitation of CRL is the fact that updates must be frequently dowloaded to keep the list current. OCSP overcomes this limitation by checking certificate status in real time.
