Enigma Project Cracks Second Code

Online codebreaking enthusiasts working to solve a series of German World War II ciphers have cracked the second of three codes. Thousands of users around the world have joined the M4 Project, using spare computing power to crack the codes.

The messages were encoded using the German Enigma machine, and outfoxed wartime experts at Bletchley Park. Project leaders have already failed to crack the last remaining message, but insist it can be broken.

The three messages were unearthed by amateur historian Ralph Erskine, who submitted them to a cryptology journal in 1995 as a challenge for codebreakers. Click here for more information.
