The "Bob the Butcher" software is a distributed password
cracker package.

WARNING
This is ALPHA software, full of bugs, some of them being
likely to be security holes.
Besides, there is no client authentification, so anybody
could impersonate a client and alter your search results.
Only use it on a trusted network!

It features:
  • Cipher's near source compatibility with John the
    Ripper. Bob the Butcher benefits from the fast
    algorithms that have been develloped for John:

  • Password cracking speed scales linearly with the
    number of cracking clients.

  • Central server that can handles several jobs,
    supporting different priorities (in the future :).

  • Smart keyspace distribution when several jobs are
    using the same algorithm (not for now).

Changelog:

New to v0.7.1 :

  • Increased solaris compatibility
  • Many cipher bugs resolved
  • Still bugs with original john's plugins under sparc
Usage:

Build instructions
Only works on pentium or later (and solaris now ...)!
./configure --enable-debug
make
cd bob_client
./bob_client -b

If it segfaults, try again with:
./configure --enable-debug --disable-sse2

bob_server
Just run ./bob_server -k SECRET_KEY

bob_admin
Use it to add jobs and check status. For now only
the following commands work:

  • newjob : add a new job
  • status : gives general status
  • jobinf : give detailled status
Don't forget to use the -k switch for PSK.

bob_client Put this one on as many computers as possible,
and just run:
./bob_client -d -k SECRET_KEY server_host_name

Next version is due soon.
