Shishi 0.0.24

Subject: Shishi 0.0.24

I am pleased to announce the availability of Shishi version 0.0.24!

Shishi is an implementation of the Kerberos 5 network authentication
system.  Shishi can be used to authenticate users in distributed
systems.  Shishi is part of a GNU system.

Noteworthy changes since the last version:

** Fix bug in shishid which caused it to listen on standard input and crash.

** Pre-authentication support.
Only the PA-ENC-TIMESTAMP, ETYPE-INFO and ETYPE-INFO2 mechanisms are
supported.  Tested againt MIT, Heimdal, and Windows 2000 KDCs.

** Clarified the copyright on lib/kerberos5.asn1.

** Updated gnulib compatibility files.

** Fix some memory leaks and crashes.

Thanks to Russ Allbery and Elrond for packaging and testing of this

Shishi contains a library ('libshishi') that can be used by
application developers to add support for Kerberos 5.  Shishi contains
a command line utility ('shishi') that is used by users to acquire and
manage tickets (and more).  The server side, a Key Distribution
Center, is implemented by 'shishid', and support X.509 authenticated
TLS via GnuTLS.  Of course, a manual documenting usage aspects as well
as the programming API is included.

Shishi currently supports AS/TGS exchanges for acquiring tickets,
pre-authentication, the AP exchange for performing client and server
authentication, and SAFE/PRIV for integrity/privacy protected
application data exchanges.  The DES, 3DES, ARCFOUR, and AES
cryptographic algorithms are supported.

Shishi aims to be internationalized, thread safe and portable.  Shishi
is written in ANSI/ISO C89, and has been ported to numerous platforms,
including most major Unix platforms and Windows, running on devices
including iPAQ handhelds and S/390 mainframes.  Shishi can also be
cross compiled to Microsoft Windows using mingw32 and embedded
platforms such as the Motorola Coldfire.

Current work items include improvements on the server (KDC),
integration of initial authentication via OpenPGP using GnuTLS,
set-passwd implementation, and a LDAP backend for the Shisa library
used in the KDC for information storage.  Assistance is appreciated on
any of these (or other) items.

Known problems in this release:

** Libgcrypt is required, the gnulib crypto code-path has regressed
   since the last release.  This will hopefully be fixed in the next

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

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