CRL

public abstract class CRL extends Object

Known Direct Subclasses X509CRL X509CRL Abstract class for an X.509 Certificate Revocation List (CRL).

This class is an abstraction of certificate revocation lists (CRLs) that have different formats but important common uses. For example, all CRLs share the functionality of listing revoked certificates, and can be queried on whether or not they list a given certificate.

Specialized CRL types can be defined by subclassing off of this abstract class.
