DES-II-1 Encryption Challenge

UNB Cryptography LOGO


The
UNB Crytography Group helped in the international effort to crack the DES encryption algorithm. Using a large number of computers working together in a distributed computing system, and using a brute force attack (trying all possible keys), the distributed.net cracked the DES algorithm in RSA's second DES challenge.

DES-II-1 RESULTS


The winning key to the challenge was detected and submitted to RSA Labs at 02:26 GMT on Monday, 23-Feb-1998.

The correct key, 76 9E 8C D9 F2 2F 5D EA, revealed the words which we've been anticipating these past 39 days: "The secret message is: Many hands make light work."
