It started out as an effort to break RC5-56, a 56-bit encryption algorithm that had a $10,000 USD prize available to anyone who could find the key. That challenge was solved on October 19 1997 after 250 days. The next project was the RC5-64 challenge which took nearly five years to complete before the correct key was found on July 14 2002.
Currently, distributed.net is working on RC5-72 (breaking RC5 with a 72-bit key), and the OGR-25 project, which is searching for 25 point optimal Golomb rulers.

Dnetc
Dnetc is the name of the program which users run to complete the challanges. It is available for a large amount of platforms. It is a command line program with an interface to configure it. x86/Win32 is the most used configuration, with x86/Linux and PPC/OS X in second and third places as of May 2005.

Cow
A cow head is used as the icon of the application and is the project's mascot. Its use is explained on the site's FAQ [2] (http://faq.distributed.net/?file=80)
