The current passes through these rotors (or Walzen in German) 2 times, right now we’ll talk about the first time. Side note: A typical Enigma contains 5 rotors/rolls, but only 3 of those actually turn, the other two are the ETW, which we have already discussed, and the reflector, so generally such an Enigma would be referred to as an Enigma with 3 rotors. These rotors actually do turn, and are what made the Enigma so difficult to crack. Now we’re getting to the actual encryption. If you’re interested in the historical wiring tables, you can find some of the known ones here. We’ll talk about them in in detail later on, since it’s a little bit complicated. The rotor is still constructed simliarly to the other (rotating) rotors, it has a wiring table, this is basically a mapping of characters, as well as a Grundstellung and Ringstellung, which can further alter the wiring table. This functions similarly to the plug-board, in that it can change a letter to another one, and within one configuration of the machine this mapping will not change, but whereas with the plug-board a letter didn’t necessarily have to change, here it does have to change.ĭespite it’s name, ( ETW = Eintrittswalze something like entry-rotor in German), this rotor does not actually rotate (Which is why the mapping of characters does not change within a configuration). A scenario where A maps to B, but B maps to C is impossible.Īfter the electrical current has passed through the plug-board, and the letter has potentially been swapped with another one, it continues to the next stage. Now, when you press the A key on the keyboard, he rest of the encryption will proceed as if you had pressed U, similarly, pressing U means the rest of the process proceeds as if you had pressed A. For example, you could connect the letters A and U. This is supposed to add an extra layer of complexity.īefore using the Enigma, one would have set-up the plug-board by connecting some letters with each other. The plug-board serves the purpose of mapping one letter to another, so it essentially switches two letters with each other. When you press a letter on the Enigmas keyboard, electrical current flows through the plug-board ( Steckbrett in German). I’ll jump straight to a detailed step-by-step walkthrough.

I’ll assume you have a basic understanding of the way the Enigma operates. You can find more information in the py directorys readme. Since the Enigma encryption doesn’t hold up to modern standards (Don’t ever use it for anything important) speed shouldn’t be too much of a concern anyways. I wrote it a while ago, and the codebase is somewhat messy and unorganised. This implementation is written in python. That means you can use this Enigma with modern Unicode and encrypt text with emojis etc.

It also allows for additional rotors to be used (Not something you could originally do, for obvious reasons) and you have full control over the alphabet. It supports historical models of the Enigma, like the M3, M4, Enigma Z and many, many more.

This project is a simulator for the Enigma machine. Among them was of the course the now infamous Alan Turing, often called the father of theoretical computer science and artificial intelligence.īased on the work of Marian Rejewski, Turing (And later Gordon Welchman) developed a machine called Bombe (Based on the original Polish name bomba, or bomba kryptologiczna) that exploited a flaw in the design of the Enigma machine and ultimately allowed them to reliably break the encryption.Īfter watching The Imitation Game (A very good movie, despite historical inaccuracies, about Turing and the cracking of Enigma, I highly recommend it.), I became somewhat obsessed with Turing, his work and especially the Enigma.

There were also models available for purchase to businesses.ĭuring World War II, it gave Germany a big advantage over the allies, although the Enigma was eventually cracked by them, more specifically by a large group of code breakers in Bletchley Park who based their work on that of some Polish engineers. It was considered un-crackable, and was therefore used by the German military to communicate securely. The Enigma machine was an encryption device used mainly developed by the Germans during the second world war.
