Cryptanalysis of the Enigma bombes were, however, very fast and the most successful. They were extensively used by Bletchley Park over teleprinter links (using the Combined Cipher Machine) to OP-20-G for both 3-rotor and 4-rotor jobs. Although the German army, SS, police, and railway all used Enigma with similar procedures, it was the "Luftwaffe" (Air Force) that was the first and most fruitful source of Ultra intelligence during the war. The messages were decrypted in Hut 6 at Bletchley Park and turned into intelligence reports in Hut 3. The network code-named ‘Red’ at Bletchley Park was broken regularly and quickly from 22 May 1940
Mass surveillance in the United Kingdom and metadata for 30 days. A number of other GCHQ operations were revealed, including hacking into telecoms equipment, access to fibre-optic cables and programmes operated jointly with the NSA. GCHQ was originally established after the First World War as the "Government Code and Cypher School" (GC&CS) and was known under that name until 1946. During World War II, staff including Alan Turing worked on decoding the German Enigma machine, and many other foreign systems. In 1940, GC&CS was working on the diplomatic codes and ciphers of 26 countries, tackling over 150 diplomatic cryptosystems. After World War II, the United Kingdom
