German code breaking in World War II German code breaking in World War II German code breaking in World War II achieved some notable successes cracking British Naval ciphers until well into the fourth year of the war, but also suffered from a problem typical of the German armed forces of the time: numerous branches and institutions maintained their own cryptographic departments, working on their own without collaboration or sharing results with equivalent units. This led to duplicated effort, to a fragmentation of potential, and to lower efficiency than might have been achieved. There was no central German cryptography agency comparable to the British Bletchley Park facility.
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
