Java in a Nutshell, 5th Edition [Electronic resources]

This class represents an X.509 CRL, which consists primarily of a set of X509CRLEntry objects. The various methods of this class provide access to the full details of the CRL, and require a complete understanding of the X.509 standard, which is beyond the scope of this reference. Use verify( ) to check the digital signature of the CRL to ensure that it does indeed originate from the the source it specifies. Use the inherited isRevoked( ) method to determine whether a given certificate has been revoked. If you are curious about the revocation date for a revoked certificate, obtain the X509CRLEntry for that certificate by calling getrevokedCertificate( ). Call getThisUpdate( ) to obtain the date this CRL was issued. Use getNextUpdate( ) to find if the CRL has been superseded by a newer version. Use geTRevokedCertificates( ) to obtain a Set of all X509CRLEntry objects from this CRL.

Obtain an X509CRL object by creating a CertificateFactory for certificate type "X.509" and then using the generateCRL( ) to parse an X.509 CRL from a stream of bytes. Finally, cast the CRL returned by this method to an X509CRL.
