CSG Enigma Breaking Project

Crypto Simulation Group

The Crypto Simulation Group (CSG) has done a tremendous effort to break many Enigma messages. With all the current publicity about the three Kriegmarine Enigma messages, decrypted by Stafan Krah's M4 Project, one might forget CSG's codebreaking efforts to decrypt more than 500 authentic unbroken Enigma messages, enciphered with the 3-rotor Enigma I.

Meanwhile, Frode created Breaking German Wehrmacht Ciphers, a special portal with all important decrypts and additional historical background information.

I already reported on Decrypting Nazi Secrets at Frode Weierud's CryptoCellar. This huge project started in 2003 and several of those messages are already broken. Some contained sensational stuff.
