WebApr 18, 2015 · It was a hard wired machine with a gear based permutation group. It had a clock permutation system: It permutes the letters in a hardwired fashion and each key click shifts that set permutation one space. After 26 shifts in the first gear, it does one turn of the second gear. After 26 turns of the second gear, it turns the third gear. http://www.crypto-it.net/eng/simple/enigma.html

WebIn 1921, Boris Hagelin developed his first cipher machine. Since then, he produced a wide range of machines, of which the M-209 (shown here) is probably the most well-known one. After WWII, the company (Crypto AG) developed numerous other machines and models, and is still in business today.
