,CertAttrSet
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).
