What does the Lorenz machine do?

Answer 1

The Lorenz machine, used during World War II, was a cipher machine employed by the German military for encrypting messages. It utilized a complex system of gears and wheels to produce a polyalphabetic substitution cipher, which was more sophisticated than earlier encryption methods. The machine's encrypted messages were known as "Tunny," and breaking its codes was a significant achievement for Allied cryptanalysts, contributing to the war effort. Its decryption played a crucial role in intelligence operations, particularly at Bletchley Park.
