Encryption machine. A woman using an electric code machine for encrypting and decrypting secret messages. Electro-mechanical encryption machines such as this were built by combining the mechanical parts of a standard typewriter with the electrical parts of an electric typewriter, connecting the two through a scrambler. Such rotor machines would become the primary form of encryption during World War II. Photographed in 1923. | |
