ENIGMA SIMULATOR SOURCE CODE SOFTWARE

Because of the reflector, which sends back electricity through another set of rotor contacts, a letter can never encode to itself. Once a key is pressed and held down, the encoded result is shown in the lamp-field. Geared stepping machines and their more frequent irregular stepping are also simulated. For lever stepping machines, the double stepping anomaly is faithfully replicated and can be observed by setting the rotors to AADQ. Pressing an A-Z key animates the rotors rotating.ĭepending on the rotor position and the machine type, anywhere from 1 to 4 rotors will turn. The menu structure is as follows, upon powerup, the simulator shows the rotor position (AAAA) and is ready to encode with the current settings loaded from non-volatile internal storage memory (FLASH). Enigma M4 (thin B and thin C reflectors), Norway 'NorEnigma', S 'Sonder-Enigma', D (commercial), K (Swiss), R 'Rocket' (Railway), T 'Tirpitz' (Japan), KD with rewirable UKWD, A-865 Zählwerk (1928), G-111 (Hungary/Munich), G-260 (Abwehr, Argentina), G-312 (Abwehr, Bletchley) The list of machines emulated is as follows:Įnigma I (A, B, and C reflectors), Enigma M3 (B, C, and rewirable UKWD reflector). The accuracy of this simulator has been verified against Daniel Palloks Universal Enigma v2.5.

Once 10 plugs are set, an additional scrambler, a software emulation of the UHR switch can be enabled and set to any of its 40 positions. For machines with a plugboard, one is emulated in software as well. There are a couple of oddball machines like the Swedish Enigma B A-133 and the Enigma Z30 that this does not simulate.

PicoEnigma simulates all well known enigma machines that have 26 keys. Scroll all the way to the bottom for a demonstration video. This is #PicoEnigma by It is a very small, Arduino based Universal Enigma Machine Simulator that's open source and hackable.
