ENIGMA M4 - Breaking German Navy Ciphers edit / delete

"The "Breaking German Navy Ciphers" Project was founded in 2012. The goal is to break original radio messages, which were encoded with the famous German ENIGMA cipher machine. Up to now, we've succeeded in deciphering over 60 original World War II Enigma I M3 and M4 messages." This includes a batch of messages found in a sunken U-boat in the mid-80s -- surprisingly readable given 40 years underwater!

"These pages give an introduction to substitution ciphers and then go on to explain exactly how the Enigma machine worked and how it was used." A good description of how to actually implement it in software.

U-boat Archive edit / delete

Can't remember how I got here, but the US reports on captured U-boats are quite interesting. (They thought the hulls were neat but the plumbing wasn't very good.)
