Class X509Impl

java.lang.Object

java.security.cert.Certificate

java.security.cert.X509Certificate

oracle.security.crypto.jce.cert.X509Impl

All Implemented Interfaces:

java.io.Serializable, java.security.cert.X509Extension

public class X509Impl
extends java.security.cert.X509Certificate

This class encapsulates X.509 Version 3 certificates.

Both RSA and DSA certificates are supported. This class provides the methods for reading and writing X509 Version 1 fields of the certificate.

Any X509 v3 extension can be handled through X509Extension. A subset of the standard extensions defined in RFC 2459 are conveniently implemented as subclasses of X509Extension, in the oracle.security.crypto.cert.ext package.
