Optimal 24 Mark Golomb Rulers:

The OGR-24 project was officially concluded on 1-Nov-2004 in the public announcement. We proved that 24/9-24-4-1-59-25-7-11-2-10-39-14-3-44-26-8-40-6-21-15-16-19-22 was the most optimal 24 mark ruler possible.
RC5-64:

The RC5-64 project ended on July 14, 2002 when the announcement was made that the key 0x63DE7DC154F4D039 that produced the plaintext output "The unknown message is: Some things are better left unread" had been found.
CS-Cipher Challenge:

The CS-Cipher Challenge was organized by CS Communications & Systems and was planned to last one year, through March 17, 2000. distributed.net found the key to decypher the unknown plaintext on January 16, 2000, after testing more than 98% of the keyspace in under 2 months! This challenge was meant to demonstrate how weak a 56-bit key is against brute force attacks.
DES-III

This project began on January 13th, 1999, at 9 AM PST. We successfully finished it after 22.5 hours with the help of EFF's Deep Crack custom DES cracker and achieved the $10K prize. For more information, feel free to peruse our DES-III headquarters.
DES II-2:

Just like its predecessor, DES-II-2 was a timed contest. However, this time we were not able to find the key before the Electronic Frontier Foundation discovered the plaintext to be "It's time for those 128-, 192-, and 256-bit keys" through their use of custom hardware.
DES II-1:

The DES II-1 challenge was a time-dependant contest from RSA Labs which began on 13-Jan-1998 and was completed on 24-Feb-1998 with the key 76 9E 8C D9 F2 2F 5D EA and produced the plaintext message "The unknown message is: Many hands make light work."
RC5-56:

RC5-56 ended October 22, 1997 when the announcement was made that the the key 0x532B744CC20999 presented us with the plaintext message "The unknown message is: It's time to move to a longer key length" was found.

Στηρίζεται και αυτό στα idle cycles(κοινώς ένα μικρό proggie τρέχει όταν το pc δεν κάνει τπτ και προσπαθεί να δοκιμάσει ένα τμήμα απο όλους τους πιθανούς συνδιασμούς για να σπάσει την κρυπτογράφηση του κειμένου) και το current project είναι το σπάσιμο ενός μυνήματος encrypted με RC5 στα 72bits.

Current Information

4,012,663 Blocks were completed yesterday (0.000365% of the keyspace) at a sustained rate of 46 Blocks/sec.

17,234,256,354,869,247 Keys were completed yesterday (0.000365% of the keyspace) at a sustained rate of 199,470,559,663 Keys/sec.

The odds are 1 in 273,485 that we will wrap this thing
up in the next 24 hours. (This also means that we'll
hit 100% in 273,485 days at yesterday's rate.)
