extends Extension
Class Inheritance
Known Direct Subclasses
sun.security.x509.DeltaCRLIndicatorExtension
Imports
java.io.IOException, java.math.BigInteger, sun.security.util.*
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.
