Almost everyone has heard of the infamous German Enigma machine, but only a handful know about the bigger and better British equivalent known as Typex.  Typex was a highly sophisticated cipher machine used by the British military during World War II, which, unlike Enigma, was never cracked.  In this episode, we explore the origin and development of the machine, dig into the mechanisms that make it work, and explain why it was so secure.  In addition, we examine its evolution over time, as well as its impact both during and after the war.
