A cipher machine is a mechanical device for encoding and decoding messages.
The cipher "0" is commonly known as the "null cipher" and the "zero cipher." A null cipher encodes a message by hiding it within a larger body of text, often using specific letters or words to reveal the intended message, while the zero cipher is a more general term that can refer to any encoding that represents information with no visible changes in a certain context.
unconditional security no matter how much computer power or time is available, the cipher cannot be broken since the ciphertext provides insufficient information to uniquely determine the corresponding plaintext computational security given limited computing resources (eg time needed for calculations is greater than age of universe), the cipher cannot be broken

Turing did not work on the Enigma, it was a German machine. However he did do some work on the British Bombe machines that were used to crack the Enigma machine cipher. Later he saw Tommy Flowers' Colossus electronic computer, designed to crack the German Lorenz SZ40/42 machine cipher. This inspired him after the end of the war to begin work on programmable electronic computers.

I don't know what the Germans called it, but when the British got ahold of it and began trying to decrypt it, they called it the "Enigma machine".

The circular reflector is a part of a cipher machine used by a code breaker. It made sure that the encrypted letter in a cipher could never be the actual letter itself. This device was useful in cracking codes during WWII.
The Lorenz cipher machine was a teleprinter cipher used by the German military during World War II, designed to encrypt messages. It utilized a complex system of 12 rotors, each contributing to the encryption process by altering the plaintext based on a series of predefined settings and a variable key. The machine generated a stream of pseudo-random characters that substituted letters in the plaintext, making the output appear nonsensical. To decode the messages, the recipient needed to know the specific rotor settings and the key used for encryption, which added a layer of security.
The BAUDOT code is made from a cipher. The cipher that does this is also known as a Bacon cipher.

A machine used to create coded messages is often referred to as a cipher machine. These devices, such as the Enigma machine used during World War II, encrypt plaintext into ciphertext using various algorithms and keys. They can employ mechanical, electronic, or digital methods to transform messages, ensuring secure communication by making the content unreadable to unauthorized users. Cipher machines have played a crucial role in military and diplomatic communications throughout history.
