UK Cipher Machines
Over the years, the United Kingdom (UK) produced a wide range of different cipher machines, ranging from mechanical and electro-mechanical manchines, to fully electronic devices. Quite often these machines were (partly) developed by the Government Communications Headquarters (GCHQ), sometimes in cooperation with the US National Security Agency (NSA).
