dCode can code/decoder 3 enigma machines (Wehrmacht/Luftwaffe with 3 rotors and Kriegsmarine with 3 or 4 rotors). Each model has its own rotos and reflectors.
|Wehrmacht / Luftwaffe 3||I, II, III, IV and V||B or C|
|Kriegsmarine M3||I, II, III, IV, V, (sometimes VI, VII and VIII)||B or C|
|Kriegsmarine M4||I, II, III, IV, V, VI, VII, VIII, Beta and Gamma||BThin or CThin|
Rotors have notches. For rotor I, going from Q to R advances the next rotor, notches depends on each rotors and cannot be configured.
Rotors can be mounted in any order but Beta and Gamma can only be in position 4 and must use B Thin or C Thin reflector.
A rotor can have variable initial position (there are 26 positions) which have to be set each time. Rotors have a letter wheel which was fixed in first Enigma machines, but can be set in the latest versions, its position is called Ringstellung.
The ciphered message has only letters, and no letter in the same position as the initial message.
On some rotor wheel, the alphabet is fixed, in this case rotor and wheel are the same thing, but sometimes the wheel is not fixed and can be shifted by an offset from the rotor.
In the early 1920s
