The Lorenz cipher was a high-level German cipher machine used during World War II, developed by the Lorenz company around 1940. It was designed to encrypt teleprinter communications for the German Army, producing ciphertext in the Baudot code format. Unlike the simpler Enigma machine, the Lorenz cipher used twelve wheels with a complex system of rotations to generate a pseudo-random key stream, creating a stream cipher that combined plaintext bits with key bits via modulo-2 addition (XOR).
