 Reflector (cipher machine)

Reflector, as a term in the context of cipher machines, typically refers to a part of the encryption mechanism used in certain historical cipher machines, most notably the Enigma machine used by Germany during World War II. In the Enigma machine, a reflector is a crucial component that reflects the electrical current back through the encryption path. The basic functioning of the Enigma involves the passing of electrical signals through a series of rotors, which substitute letters according to a predefined key.
