 Official List Announcement
 October 22, 1997 
 
It is a great privilege and we are excited to announce that at 13:25 GMT on
19-Oct-1997, we found the correct
solution for RSA Labs' RC5-32/12/7 56-bit secret-key challenge. Confirmed by
RSA Labs, the key
0x532B744CC20999 presented us with the plaintext message for which we have been
searching these past
250 days. 

The unknown message is: It's time to move to a longer key length 
 
In undeniably the largest distributed-computing effort ever, the Bovine RC5
Cooperative
(http://www.distributed.net/), under the leadership of distributed.net, managed
to evaluate 47% of the keyspace,
or 34 quadrillion keys, before finding the winning key . At the close of this
contest our 4000 active teams were
processing over 7 billion keys each second at an aggregate computing power
equivalent to more than 26
thousand Pentium 200's or over 11 thousand PowerPC 604e/200's. Over the course
of the project , we
received block submissions from over 500 thousand unique IP addresses. 

The winning key was found by Peter Stuer with an Intel Pentium Pro 200 running
Windows NT Workstation,
working for the STARLab Bovine Team coordinated by Jo Hermans and centered in
the Computer Science
Departm ent (DINF) of the Vrije Universiteit (VUB) in Brussels, Belgium.
(http://dinf.vub.ac.be/bovine.html/).
Jo's only comments were that "$1000 will buy a lot of beer" and that he wished
that the solution had been found
by a Macintosh, the platform that repr esented the largest portion of his
team's cracking power. Congratulations
Peter and Jo! 

Of the US$10000 prize from RSA Labs, they will receive US$1000 and plan to host
an unforgettable party in
celebration of our collective victory. If you're anywhere near Brussels, you
might want to find out when the party
will be held. US$8000, of course , is being donated to Project Gutenberg
(http://www.promo.net/pg/) to assist
them in their continuing efforts in converting literature into electronic
format for the public use. The remaining
US$1000 is being retained by distributed.net to assist in fund ing future
projects. 

Equally important are the thanks, accolades, and congratulations due to all who
participated and contributed to
the Bovine RC5-56 Effort! The thousands of teams and tens of thousands of
individuals who have diligently
tested key after key are the reason we are so successful. 

The thrill of finding the key more than compensates for the sleep, food, and
free time that we've sacrificed! 

Special thanks go to all the coders and developers, especially Tim Charron, who
has graciously given his time and
expertise since the earliest days of the Bovine effort. Thanks to all the
coordinators and keyserver operators:
Chris Chiapusio, Paul Chvost ek, Peter Denitto, Peter Doubt, Mishari Muqbil,
Steve Sether, and Chris Yarnell.
Thanks to Andrew Meggs, Roderick Mann, and Kevyn Shortell for showing us the
true power of the Macintosh
and the strength of its users. We'd also like to thank Dave Avery for
attempting to bridge the gap between
Bovine and the other RC5 efforts. 

Once again, a heartfelt clap on the back goes out to all of us who have run the
client. Celebrations are in order.
I'd like to invite any and all to join us on the EFNet IRC network channel #rc5
for celebrations as we regroup and
set our sights on the n ext task. Now that we've proven the limitations of a
56-bit key length, let's go one
further and demonstrate the power of distributed computing! We are, all of us,
the future of computing. Join the
excitement as the world is forced to take notice of th e power we've harnessed. 

Moo and a good hearty laugh.

Jeff Lawson - keymaster/server network design and morale booster
