Class Certificate

java.lang.Object
  java.security.cert.Certificate
      jsdsi.Certificate

All Implemented Interfaces:

java.io.Serializable

public class Certificate

extends java.security.cert.Certificate

A Cert along with its validators (verification path, signature, and online test results). Whereas a Cert is simply an unauthenticated statement, a Certificate is self-validating and thus can be considered authentic if verify() succeeds. A Certificate is serialized as a SPKI/SDSI Sequence.
