Abstract

The Generic Security Service Application Program Interface (GSS-API), as defined in RFC-1508, provides security services to callers in a generic fashion, supportable with a range of underlying mechanisms and technologies and hence allowing source-level portability of applications to different environments. This specification defines GSS-API services and primitives at a level independent of underlying mechanism and programming language environment, and is to be complemented by other, related specifications:

Generic Security Service Application Program Interface, Version 2

Status of this Memo

This document specifies an Internet standards track protocol for the

Internet community, and requests discussion and suggestions for

improvements. Please refer to the current edition of the "Internet

Official Protocol Standards" (STD 1) for the standardization state

and status of this protocol. Distribution of this memo is unlimited.

Abstract

The Generic Security Service Application Program Interface (GSS-API),

as defined in RFC-1508, provides security services to callers in a

generic fashion, supportable with a range of underlying mechanisms

and technologies and hence allowing source-level portability of

applications to different environments. This specification defines

GSS-API services and primitives at a level independent of underlying

mechanism and programming language environment, and is to be

complemented by other, related specifications:

documents defining specific parameter bindings for particular

language environments

documents defining token formats, protocols, and procedures to be

implemented in order to realize GSS-API services atop particular

security mechanisms

This memo revises RFC-1508, making specific, incremental changes in

response to implementation experience and liaison requests. It is

intended, therefore, that this memo or a successor version thereto

will become the basis for subsequent progression of the GSS-API

specification on the standards track.
