      Generic Security Service API Version 2: Java Bindings Update

Abstract

   The Generic Security Services Application Program 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" (RFC 2853).
   This document obsoletes RFC 2853 by making specific and incremental
   clarifications and corrections to it in response to identification of
   transcription errors and implementation experience.

   The GSS-API is described at a language-independent conceptual level
   in "Generic Security Service Application Program Interface Version 2,
   Update 1" (RFC 2743).  The GSS-API allows a caller application to
   authenticate a principal identity, to delegate rights to a peer, and
   to apply security services such as confidentiality and integrity on a
   per-message basis.  Examples of security mechanisms defined for GSS-
   API are "The Simple Public-Key GSS-API Mechanism" (RFC 2025) and "The
   Kerberos Version 5 Generic Security Service Application Program
   Interface (GSS-API) Mechanism: Version 2" (RFC 4121).
