A CRL file contains a list of revoked digital certificates. It enables security administrators to block untrusted entities. The file typically stores information about the certificates like the issuer and revocation date. Web servers and encryption software often use CRL files.
The CRL file format supports 3 operating systems. On each system, different software handles CRL files. For example, over 400 file formats can be opened with File Viewer Plus.
A Certificate Revocation List is declared by a certificate authority. It cryptographically signs a list of revoked certificates. CRL files may use PEM or DER encoding formats. They are becoming less common compared to the OCSP protocol.
To view a PEM-encoded CRL file, use OpenSSL. Identification contents include “—–BEGIN X509 CRL—–”.
