Interface KerberosTokenDecoder

All Known Implementing Classes:

KerberosTokenDecoderImpl

public interface KerberosTokenDecoder

This interface defines a pluggable way to obtain a session key given an AP-REQ Kerberos token and a Subject. The session key is needed on the receiving side when it is used for message signature or encryption. A default implementation is not shipped with WSS4J due to a dependency on internal APIs or ASN1 parsers.
