This abstract class represents a certificate revocation list (CRL). A CRL is an object issued by a certificate authority (or other certificate signer) that lists certificates that have been revoked , meaning that they are now invalid and should be rejected. Use a CertificateFactory to parse a CRL from a byte stream. Use the isRevoked( ) method to test whether a specified Certificate is listed on the CRL . Note that type-specific CRL subclasses, such as X509CRL , may provide access to substantially more information about the revocation list. public abstract class CRL { // Protected Constructors protected CRL (String type ); // Public Instance Methods public final String getType ( ); public abstract boolean isRevoked (java.security.cert.Certificate cert ); // Public Methods Overriding Object public abstract String toString ( ); } SubclassesX509CRL Passed ToCRLSelector.match( ) , X509CRLSelector.match( ) Returned ByCertificateFactory.generateCRL( ) , CertificateFactorySpi.engineGenerateCRL( ) |
