WebA cypher is a message written in a secret code. Spies during World War II sometimes communicated using cyphers. WebThe greatest triumphs in the history of cryptanalysis were the Polish and British solution of the German Enigma ciphers and of two teleprinter ciphers, whose output was code-named Ultra, and the American cryptanalysis of the Japanese Red, Orange, and Purple ciphers, code-named Magic.
