Shishi is an implementation of the kerberos v5 network authentication system.

Shishi can be used to authenticate users in distributed systems.

Shishi contains a library ('libshishi') that can be used by application developers to add support for kerberos v5. 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'. Of course, a manual documenting usage aspects as well as the programming API is included.

Shishi currently supports AS/TGS exchanges for acquiring tickets, the AP exchange for performing client and server authentication, and SAFE/PRIV for integrity/privacy protected application data exchanges.

Shishi is internationalized; error and status messages can be translated into the users' language; user name and passwords can be converted into any available character set (normally including ISO-8859-1 and UTF-8) and also be processed using an experimental Stringprep profile.

Most, if not all, of the widely used encryption and checksum types are supported, such as ARCFOUR, 3DES, AES and HMAC-SHA1.

This package includes a few command line tools: shishi -- Acquire and manage Kerberos tickets. keytab2shishi -- Convert MIT/Heimdal /etc/krb5.keytab's to Shishi format. ccache2shishi -- Convert MIT/Heimdal user ticket files to Shishi format.
