ENIGMA Crypter

Specifically, it is a basic version of the ENIGMA with three scramblers, which was used by the Wehrmacht and Luftwaffe units at the beginning of the war. The program uses the same internal mechanism, so it is compatible with the early version of ENIGMY (it can decrypt German wartime messages from the beginning of the war). Compatibility is not guaranteed for later versions of ENIGMY, which had more scramblers and different internal circuitry, and for the naval version of ENIGMY used by Kriegsmarine units.
