Biuro Szyfrów

The Biuro Szyfrów (Cipher Bureau ) was the Polish agency concerned with cryptology between World Wars I and II. The Bureau enjoyed notable successes against Soviet cryptography during the Polish-Soviet War, helping to preserve Poland's independence. Beginning in December 1932, the Cipher Bureau broke the German Enigma cipher and overcame the ever-growing structural and operating complexities of the evolving Enigma machine.
