Class CRLNumberExtension

java.lang.Object

sun.security.x509.Extension

sun.security.x509.CRLNumberExtension

All Implemented Interfaces:

CertAttrSet<java.lang.String>

Direct Known Subclasses:

DeltaCRLIndicatorExtension

public class CRLNumberExtension
extends Extension
implements CertAttrSet<java.lang.String>

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.
