rypTool - Software which allows encryption of text using historic algorithms The Enigma Machine - In World War II the Germans made use of an electro-mechanical rotor based cipher Known as The Enigma Machine. Allied cipher machines used in WWII included the British TypeX and the American SIGABA. The ADFGVX Cipher - invented by Colonel Fritz Nebel in 1918. The key for this algorithm is a six-by-six square of letters, used to encode a 36-letter alphabet. The Playfair Cipher - invented in 1854...
