- A UNIX password cracker for the Thinking Machine CM/2 and CM/200 Connection
- Machines is available for FTP from
-
- ftp.denet.dk:/pub/misc/cm200-UFC.tar.Z

- To quote the README file:
-
- > Overview
- > ========
- >
- > This is a password cracker for the Thinking Machines CM/2 and CM/200
- > Connection Machines. It features
- >
- > o A standalone dictionary preprocessor accepting a
- > language of rewrite rules compatible with the one
- > found in Alec Muffets 'Crack' password cracker as of
- > release 4.1f.
- >
- > o An optimized port of the UFC-crypt: a fast implementation
- > of the UNIX crypt(3) function developed by Michael Glad and
- > donated to the Free Software Foundation (FSF).
- >
- > o The password cracker itself. It supports restart of crashed
- > runs and incremental use. Incremental use means that when
- > you use a fixed dictionary, the cracker can maintain a status
- > file of already cracked passwords and passwords considered
- > uncrackable (because they've been tested in previous runs).
- > Thus it only has to waste CPU cycles on new accounts and accounts
- > with changed passwords.
- >
- > o When run with a _large_ dictionary (a 1 million word dictionary
- > obtained by preprocessing /usr/dict/words), the cracker can
- > test in excess of 50,000 passwords a second on a CM/200 with
- > 8192 processors.

- The distribution contains source code derived from the UFC-crypt implemen-
- tation of the UNIX crypt(3) encryption routines. UFC-crypt is copyright Free
- Software Foundation, Inc and is distributed under the terms of the GNU
- Library General Public License, version 2 of June 1991.
-
- Any source module in distribution which not derived from UFC-crypt is
- copyright UNI-C (Danish Computing Centre for Research and Education)
- and Michael Glad and is distributed under the GNU General Public License,
- version 2 of June 1991. Even though some ideas are adopted from the Crack
- password cracker, the distribution contains no parts derived directly or
- indirectly from this fine product.
-
- The UFC-crypt port and the cracker was done by Michael Glad in the summer
- of 1992. My thanks goes to UNI-C for making this project possible.
