What Is Enigma?

So What Is Enigma?

Enigma is machine that can make codes but also can crack codes. It was first invented in Germany and at first was used by business men to pass along private company messages. In the mid 1920's, there was a mass production of the enigma machines with over 30,000 machines being sold to the German Military.

How Was Enigma Cracked?

The Poles set up a world leading crypt analysis bureau and hired leading mathematicians to crack the codes such as Marian Rejewski. Marian Rejewski then made his own enigma machine without actually seeing one. A German traitor gave information to the Poles that the Germans routinely changed the daily key indicator setting for the codes.
