"The Generic Security Services Application Programming Interface (GSS-API) offers application programmers uniform access to security services atop a variety of underlying cryptographic mechanisms. This document updates the Java bindings for the GSS-API that are specified in ""Generic Security Service API Version 2: Java Bindings Update"" (RFC 5653). This document obsoletes RFC 5653 by adding a new output token field to the GSSException class so that when the initSecContext or acceptSecContext methods of the GSSContext class fail@ it has a chance to emit an error token that can be sent to the peer for debugging or informational purpose. The stream-based GSSContext methods are also removed in this version."
