A book cipher is a cipher in which each word or letter in the plaintext of a message is replaced by some code that locates it in another text, the key.
Elizebeth Smith Friedman was an American cryptanalyst and author who deciphered enemy codes in both World Wars and helped to solve international smuggling cases during Prohibition. Over the course of her career, she worked for the United States Treasury, Coast Guard, Navy and Army, and the International Monetary Fund. She has been called "America's first female cryptanalyst".
Hans-Thilo Schmidt codenamed Asché or Source D, was a spy who sold secrets about the German Enigma machine to the French during World War II. The materials he provided facilitated Polish mathematician Marian Rejewski's reconstruction of the wiring in the Enigma's rotors and reflector; thereafter the Poles were able to read a large proportion of Enigma-enciphered traffic.
PC Bruno was a Polish–French–Spanish signals–intelligence station near Paris during World War II, from October 1939 until June 1940. Its function was decryption of cipher messages, most notably German messages enciphered on the Enigma machine.
The Cipher Bureau was the interwar Polish General Staff's Second Department's unit charged with SIGINT and both cryptography and cryptanalysis.
Cryptography was used extensively during World War II because of the importance of radio communication and the ease of radio interception. The nations involved fielded a plethora of code and cipher systems, many of the latter using rotor machines. As a result, the theoretical and practical aspects of cryptanalysis, or codebreaking, were much advanced.
Enigma is a 2001 espionage thriller film directed by Michael Apted from a screenplay by Tom Stoppard. The script was adapted from the 1995 novel Enigma by Robert Harris, about the Enigma codebreakers of Bletchley Park in the Second World War.

Maksymilian Ciężki was the head of the Polish Cipher Bureau's German section (BS–4) in the 1930s, during which time—from December 1932—the Bureau decrypted German Enigma messages.
Antoni Palluth was a founder of the AVA Radio Company. The company built communications equipment for the Polish military; the work included not only radios but also cryptographic equipment. Palluth was involved with the German section (BS-4) of the Polish General Staff's interbellum Cipher Bureau. He helped teach courses on cryptanalysis, and he was involved with building equipment to break the German Enigma machine.
Lt. Col. Karol Gwido Langer was, from at least mid-1931, chief of the Polish General Staff's Cipher Bureau, which from December 1932 decrypted Germany's military Enigma-machine ciphers. Poland's prewar achievements paved the way for Britain's World War II Ultra secret.
Lt. Col. Jan Kowalewski was a Polish cryptologist, intelligence officer, engineer, journalist, military commander, and creator and first head of the Polish Cipher Bureau. He recruited a large staff of cryptologists who broke Soviet military codes and ciphers during the Polish-Soviet War, enabling Poland to weather the war and achieve victory in the 1920 Battle of Warsaw.
Jan Leśniak was a Polish military intelligence officer in the Interbellum and World War II.
Major Franciszek Pokorny was a Polish Army officer who, after World War I, headed the Polish General Staff's Cipher Bureau before Major Gwido Langer.
A Polish Enigma "double" was a machine produced by the Polish Cipher Bureau that replicated the German Enigma rotor cipher machine. The Enigma double was one result of Marian Rejewski's remarkable achievement of determining the wiring of the Enigma's rotors and reflectors.
The Deuxième Bureau de l'État-major général was France's external military intelligence agency from 1871 to 1940. It was dissolved together with the Third Republic upon the armistice with Germany. However the term "Deuxième Bureau", like "MI6" and "KGB", outlived the original organization as a general label for the country's intelligence service.
Ironclads is a 1991 made-for-television movie produced by Ted Turner's TNT company about the events behind the creation of CSS Virginia from the remains of USS Merrimack and the battle between Virginia and USS Monitor in the Battle of Hampton Roads, March 8, 1862 – March 9, 1862. Noel Taylor received an Emmy Award nomination for his costume designs for the production.
Second Bureau is a 1936 British spy romance film directed by Victor Hanbury and starring Marta Labarr, Charles Oliver and Arthur Wontner. It was made at Shepperton Studios and based on a novel Second Bureau by Charles Robert-Dumas. It was a remake of a 1935 French film of the same name.
Panama Patrol is a 1939 American drama film. Directed by Charles Lamont, the film stars Leon Ames, Charlotte Wynters, and Adrienne Ames, it was released on May 20, 1939. The film was known during production by the working titles of Curio Cipher and Panama Cipher.
