Currently, distributed.net is working on RC5-72 (breaking RC5 with a 72-bit key)[1], and the OGR-25 project[2], which is searching for 25 point optimal Golomb rulers. The OGR project has an expected completion date at current rates of several years (and the rate is increasing), while RC5-72 has an expected completion date of about 1,000 years (and the rate is decreasing). Both problems are part of a series— OGR is part of an infinite series; RC5 currently has eight unsolved challenges from RSA. RC5 is a block cipher notable for its simplicity. ...

History
A coordinated effort was started in February 1997 by Earle Ady and Christopher G. Stach II of Hotjobs.com and New Media Labs fame, as an effort to break the RC5-56 portion of the RSA Secret-Key Challenge, a 56-bit encryption algorithm that had a $10,000 USD prize available to anyone who could find the key. Unfortunately, this initial effort had to be suspended as the result of SYN flood attacks by participants upon the server.[3] The RSA Secret-Key Challenge is a series of cryptographic contests that were started by RSA Laboratories on January 28, 1997 with the intent of helping to demonstrate the relative security of different encryption algorithms. ...

A new independent effort, named distributed.net, was later coordinated by Jeff Lawson in March 1997 to resume the effort. The RC5-56 challenge was solved on October 19, 1997 after 250 days.[4] October 19 is the 292nd day of the year (293rd in leap years) in the Gregorian calendar. ...

The next project was the RC5-64 challenge which took nearly five years to complete before the correct key (0x63DE7DC154F4D039) was found on July 14, 2002 decrypting the message to the plaintext "some things are better left unread".[5] July 14 is the 195th day of the year (196th in leap years) in the Gregorian calendar. ...
