![]() ![]() What follows will guide you through the creation of your very own Enigma machine. There are countless stories of other encryption techniques, but none has intrigue and impact that the German Enigma had during World War 2. The Enigma remains perhaps the most popular encryption device in history. However, because The Bombe was classified, the University of Pennsylvania’s ENIAC was publicly given the crown of “first computer.” The Bombe was an incredible feat of engineering and the first electronic computer. Thanks to the work of British mathematician Alan Turing, the Allies developed The Bombe, a top-secret electronic computer used to quickly try every possible combination of letters in order to crack the Enigma code. Each key press on the keyboard would turn a rotor one step and provide a new, different path for the electricity to flow inside the machine. The Enigma operator would then key in each “random” letter and write down the resulting letter that was lit up on the machine. They would copy seemingly random letters via Morse Code from the radio. Soldiers in the field and sailors at sea would set their Enigma machines’ rotors to the same as the person sending a message. For example, a T might be pressed but the letter G would light up. The operator would press a key on the keyboard which would activate an electric circuit and light up a different letter. The most simple models had three wheels on top of the case that allowed the operator to set internal rotors into a certain position. The Enigma was an electro-mechanical machine similar to a typewriter. This gave the Allies the ability to read top secret communications during the war and greatly disrupt the Nazi German war machine. Thanks to incredible mathematicians in Poland and tenacious work by the British at Bletchley Park, the Allies broke the Enigma code. The number of possible ways to jumble a message through an Enigma was nearly 159 quintillion. The power of the Enigma came from being simple for the operator to use but difficult to determine the encrypted letter for any input letter. Of course, studying the Enigma is also a tribute to Alan Turing.The Enigma was an encryption machine famously used by the German military during World War 2. German militaries would send encrypted messages through the air using telegraphs about bombing locations with security, considering one would have to know the precise combination of rotor positioning, plugboard configuration, and other pieces in order to decode captured messages.Įven though several weaknesses were discovered - specially by the Allies forces - allowing one to break the code, the Enigma encryption algorithm is a fun way to study a little bit of cryptography. This is a simulator for the Enigma machine, one of the most incredible applications of cryptography during World War I and II. ![]() For about three weeks, I’ve studied the machine technical details, wrote the simulator code in JavaScript and Node.js using a Test-Driven Development approach, created a web interface, and documented the steps in blog articles. Enigma machine simulator in JavaScript for didactic purposes.Īs part of my #100DaysOfCode initiative, I developed an Enigma machine simulator from the ground up. ![]()
