British Government Code and Cypher School

The British Government Code and Cypher School (GC&CS), established in 1919, was a secret organization responsible for intercepting, analyzing, and decoding enemy communications during wartime. Based at Bletchley Park during World War II, it employed cryptanalysts to break complex German codes, most famously the Enigma cipher. Their efforts significantly shortened the war and saved countless lives, marking it as a pioneering center in intelligence and cryptography. Today, GC&CS is known as GCHQ, the UK's intelligence and security agency, continuing its mission of secure communications and information assurance.
