The rotor has a ring, with the letters "A" through "Z" (or "01" through "26") engraved on the outer circumference of the ring.
This rotation of the rotor changes the wiring for encryption for each character, so even if you enter the same character, it will be converted to a different character from the previous one. The rotation of the rotor starts with the rotor on the right side, and when it reaches the notch on the rotor, the rotor on the left side also rotates by one step. When you enter a character from the keyboard, the rotor rotates one step. The characters of the input and output terminals that are not wired with cables will not be converted. For example, if you connect "A" and "M" with a cable, "A" will be converted to "M" and "M" to "A". The plugboard has input and output terminals for 26 alphabets, from "A" to "Z." By connecting any two alphabets with a cable, the two characters can be converted. In some Enigma machines, there is a plugboard at the front of the ETW. The plugboard is a mechanism that allows the transliteration to be wired by the user. For example, the rotor "I" of Enigma I is wired as follows: the letter "A" is converted to "E", and the letter "J" coming back from the reflector is converted to "Z" by following the reverse wiring. For example, the rotor "I" of Enigma I is wired as shown below, and the letter "A" is converted to "E". The entry wheels, rotors, and reflectors are wired internally to convert the 26 letters from "A" to "Z" into other letters, and the conversion is done when the wires are energized. Lettering is performed at all locations, including the rotor. The encrypted result is displayed on the lamp board (Lampenfeld). Characters entered from the keyboard (Tastatur) pass through a plugboard (Steckerbrett), an entry wheel (ETW, Eintrittswalze), three or four rotors (Walze), a reflector (UKW, Umkehrwalze), and then the reverse. The Enigma machine consists of the following components. Spanish Enigma, Sonderschaltung / Delta (A 16101).
It supports encryption of 26 characters from "A" to "Z".Ĭharacter substitution is done using the Enigma cipher machine, and DenCode supports the following Enigma machine simulations
The Enigma cipher is a type of commutative cipher that encrypts letters by replacing them with other letters.
