Name

Class java.security.cert.X509CRL

Synopsis

A Certificate Revocation List (CRL) is a list of certificates whose keys are no longer valid. This class represents CRLs as defined in the X.509 standard. If you have a CRL file that you would like to examine, you can construct an X509CRL object from the file using one of the getInstance() methods. A CRL, just like a certificate, has an internal signature that protects its integrity. To verify the integrity of the CRL itself, call one of the verify() methods with the issuer’s public key. To find out if a particular certificate is revoked, call the isRevoked() method with the certificate’s serial number.
