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. Most have seen how to encrypt messages using a simple cipher like this. 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. But it’s really quite simple.
