Class CRLNumberExtension

  • All Implemented Interfaces:
    java.io.Serializable, CertAttrSet

    public class CRLNumberExtension
    extends Extension
    implements CertAttrSet
    Represent the CRL Number Extension.

    This extension, if present, conveys a monotonically increasing sequence number for each CRL issued by a given CA through a specific CA X.500 Directory entry or CRL distribution point. This extension allows users to easily determine when a particular CRL supersedes another CRL.
