Description

"A team at Bletchley Park have been working since the relevant information was declassified to build a replica of the Colossus machines that were used at Bletchley Park adn in the US to crack messages encrypted by the Lorenz machines. Unlike Enigma, where once you'd figured out the encryption settings for the day on a particular network, you could easily decrypt a whole day's traffic, the Lorenz machines automatically changed part of their settings for every message, so each message was a fresh challenge."

Here's the teletype at the output end.
