Generic Security Service Library (GSSLib) 1.0.0

From: Simon Josefsson
Subject: Generic Security Service Library (GSSLib) 1.0.0
Date: Tue, 30 Mar 2010 18:46:48 +0200
User-agent: Gnus/5.110011 (No Gnus v0.11) Emacs/23.1 (gnu/linux)

GSSLib is an implementation of the Generic Security Service
Application Program Interface (GSS-API).  GSS-API is used by network
servers to provide security services.  For example, GSS can be used to
authenticate a client against SMTP or IMAP servers.  GSS consists of a
library, a manual, and a command line tool for debugging purposes.

Noteworthy changes since the last version:

* Version 1.0.0 (released 2010-03-30)

** Rarely used GNU GSS extensions removed.
The removed APIs are gss_copy_oid, gss_duplicate_oid, and

** Align capsulation functions with Heimdal and specification document.
The functions are gss_encapsulate_token and gss_decapsulate_token.
The semantics and function prototypes changed slightly.

** Added --with-po-suffix configure parameter to modify the gettext domain.
This parameter is useful when you want to have both this version and
the older version installed at the same time.

** API and ABI modifications.
gss_copy_oid: REMOVED.
gss_duplicate_oid: REMOVED.
gss_encapsulate_token_prefix: REMOVED.
gss_encapsulate_token: MODIFIED.
gss_decapsulate_token: MODIFIED.

While written to be flexible with regards to different GSS mechanisms,
the only currently supported mechanism is Kerberos V5 via GNU Shishi.
Mutual and non-mutual authentication and channel bindings, as client
and server, is supported.  Message privacy protection using DES and
3DES is supported.

GSS aims to be internationalized, thread safe and portable.  GSS is
written in ANSI/ISO C89, and has been ported to numerous platforms, even
cross compiled to embedded platforms such as Motorola Coldfire.

GSS is a GNU project, and is licensed under the GNU General Public
License version 3 or later.

Improving GSS is costly, but you can help!  We are looking for
organizations that find GSS useful and wish to contribute back.  You can
contribute by reporting bugs, improve the software, or donate money or

Commercial support contracts for GSS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult AB, a
Stockholm based privately held company, is currently funding GSS
maintenance.  We are always looking for interesting development
