+ <description>
+ <p>
+ When SSL/TLS performs certificate path validation according to
+ <url href="http://www.ietf.org/rfc/rfc5280.txt">RFC 5280 </url> it should
+ also perform CRL validation checks. To enable the CRL checks the application
+ needs access to CRLs. A database of CRLs can be set up in many different ways.
+ This module provides an API to integrate an arbitrary CRL cache with the erlang
+ ssl application. It is also used by the application itself to provide a simple
+ default implementation of a CRL cache.
