Help break RSA's DES Crypto Challenge!

OS/2 Clients (486, Pentium, PPro) are available now...

A Call for Participation
------------------------

1) What's it all about?

  We're working on breaking the DES challenge issued by RSA Labs on Janurary
28th, 1997. Two of the other challenges, based on the RC5 algorithm with 40
and 48 bit keys, have already been broken. Especially in the 48bit RC5
challenge, a large number of Internet users contributed CPU cycles for a brute
force keyspace attack. By the end of the 48 bit RC5 challenge, over 3500 hosts
had helped by donating CPU time to achieve a peak key-testing rate of over 1.5
trillion keys/hour. We'd like for some of those hosts (and others!) to help
out with the DES challenge.
  A $10,000 prize will be awarded by RSA Labs for those who crack the
challenges first.

2) How can I help?

  First, feel free to redistribute this CFP to anyone else who you think may
be interested in participating. Especially those with a lot of CPU power. :-)

  If you've got a networked computer somewhere, you can help directly! Clients
are currently available for Intel processors (486, Pentium, and PentiumPro)
running Windows, OS/2, Linux, FreeBSD, and BSDI. Non-Intel clients are
available for PowerPC (Mac) Linux, Sun Sparc, and HP PA-RISC. The Intel
versions are all using hand-optimized assembly code. Assembly tuned versions
for the Sparc and PA-RISC versions should be available in the near future --
stay tuned!

  The only restriction is that clients can only be given to residents of the
US or Canada, due to US export restrictions. [Others may still be able to
participate; rumor has it that someone has redistributed the clients outside
the US, but I don't know the location.]

  To get the clients, visit the DESCHALL Info page (see below) for
instructions. It's simple and painless process. You just need to download and
execute the clients -- no further work on your part is required! You can visit
the statistics page to see the progress of the whole group, and your clients.

  If you have a multiple number of Unix systems you'd like to use, I've
written a few scripts to help make life simple (read: automated). Contact me
directly for further info.
