In some Enigma machines there were three rotors, and the most used was eight. And internally, each of the rotors are wired differently i.e. ![]() In the rotor, each wire has external contact points on either end. That allows some multiple of these rotors to be put side-by-side, with adjacent contacts touching. Follow the diagram above and you notice that the first Z came from the H, but the Z in the fourth position came from the K. Repeating this step of substitution followed by turning the rotor for each letter, HACKADAY becomes ZJGZLVFA. After one turn, A would now be substituted with whatever Z formerly was, namely J. By turning the rotor while leaving the letters stationary, the connections between letters change. One way to easily implement that, and it’s the way it’s done in the Enigma, is to embed all that wiring in a wheel/rotor. And even better, if they change each time a letter is encoded. An improvement would be for all those pairings to change. The ability to change the mapping is important because once someone deduces that G is the substitution for A, they’ll know that’s true for every G in the ciphertext. Rotating substitution cipher Enigma rotor wiring ![]() But those lines can be wires, electrically connecting each pair, which opens up the possibility of easily changing how the substitution is mapped through to the ciphertext. We could redraw the cipher as two alphabets with letters in alphabetical order, and draw lines between the paired letters. Adding Rotors Simple substitution cipher with wires Let’s take this further like the Enigma machine does. To decrypt it we do the reverse, look for each letter in the bottom row and substitute with the corresponding letter in the top row, getting HACKADAY. Similarly, looking for the A in the top line, we see we should substitute it with a G. Using the above cipher we look in the top line for the H and we substitute the letter below it, a Z. Let’s say we want to encrypt the word Hackaday. 4 rotor enigma simulator how to#Most have seen how to encrypt messages using a simple cipher like this. 4 rotor enigma simulator movie#Most recently the story of how it was broken was the topic of the movie The Imitation Game. Possibly the greatest dedicated cipher machine in human history the Enigma machine is a typewriter-sized machine, with keyboard included, that the Germans used to encrypt and decrypt messages during World War II. It’s also one of the machines that the Polish Cipher Bureau and those at Britain’s Bletchley Park figured out how to decipher, or break. 4 rotor enigma simulator full#But it’s really quite simple. The following is a step-by-step explanation of how it works, from the basics to the full machine. Most of the apps on this list are games, but games are always fun.
