Breaking the Code Breaking the Code Breaking the Code is a 1986 play by Hugh Whitemore about British mathematician Alan Turing, who was a key player in the breaking of the German Enigma code at Bletchley Park during World War II and a pioneer of computer science. The play thematically links Turing's cryptographic activities with his attempts to grapple with his homosexuality. It was adapted as a 1996 television film directed by Herbert Wise, with Derek Jacobi reprising his stage role as Turing. Following an eight-month run at the Theatre Royal, Haymarket in London's West End beginning on 21 October 1986, the play
Enigma machine flaw. The message setting was encoded twice, resulting in a relation between first and fourth, second and fifth, and third and sixth character. These security flaws enabled the Polish Cipher Bureau to break into the pre-war Enigma system as early as 1932. The early indicator procedure was subsequently described by German cryptanalysts as the "faulty indicator technique". During World War II, codebooks were only used each day to set up the rotors, their ring settings and the plugboard. For each message, the operator selected a random start position, let's say "WZA", and a random message key, perhaps "SXT". He moved
