| X509CRL |
Abstract class for an X.509 Certificate Revocation List (CRL).
|
|
This class is an abstraction of certificate revocation lists (CRLs) that
have different formats but important common uses. For example, all CRLs
share the functionality of listing revoked certificates, and can be queried
on whether or not they list a given certificate.
Specialized CRL types can be defined by subclassing off of this abstract
class.
