+----netscape.security.x509.SubjectKeyIdentifierExtension
- public class SubjectKeyIdentifierExtension
- extends Extension
- implements CertAttrSet
Represent the Subject Key Identifier Extension.
This extension, if present, provides a means of identifying the particular
public key used in an application. This extension by default is marked
non-critical.
Extensions are addiitonal attributes which can be inserted in a X509
v3 certificate. For example a "Driving License Certificate" could have
the driving license number as a extension.
Extensions are represented as a sequence of the extension identifier
(Object Identifier), a boolean flag stating whether the extension is to
be treated as being critical and the extension value itself (this is again
a DER encoding of the extension value).
