Actually I gather it had a lot to do with the fact that the Germans made some blunders in the way they used the Enigma that seriously compromised its security. There was reportedly a branch of the German forces that used their Enigmas differently, avoiding those mistakes, and the British never managed to crack any of their messages. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
