Yep there's lots of versions of the brutessl software, ones I know of
(in no particular order):
- Damien Doligez wrote one
- Andrew Roos wrote on (this is the one we're using for the challenge)
- Eric Young wrote one
- I wrote one
More related softwares, specifications etc.
- Piete Brookes, Andy Brown, and I wrote a protocol specification for
a SMTP style key doler - SKSP (Simple Key Search Protocol) - draft
RFC like document on brute (www url below).
- Piete wrote a unix socket based key server and client for generic
unix machines (in perl).
- Andy Brown wrote a Windows NT client which talks the same protocol
- David Byers did a MasPar port of the brutessl code

The socket based key distributer allows you to write clients which
interact with the key server. Take a look at Andy's code.

Not sure how Andy addresses this in the NT code (I don't have NT), but
for the unix client you'd just get another brute force program,
compile it and update the client.
Piete has a WWW URL for the software (the protocol spec is there too) at:
(Brute is a subsubdomain he set up for the purpose).
And the socket server runs on: sksp.brute.cl.cam.ac.uk (port 19957).
I think we're ready to start another challenge, this one a
collaborative project like the brute rc4 one. Just need some
challenges now (asked Hal about this).
