Class Overview

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.
