Electromechanical: A device that uses both electrical and mechanical components to function.
Polyalphabetic Substitution: A method of encryption that uses multiple alphabets for substitution, making it harder to crack than a simple substitution cipher.
Cryptographic Key: A piece of information, like a password or setting, used to encrypt and decrypt messages.
Bletchley Park: The British codebreaking center during World War II where Enigma and other Axis ciphers were decrypted.
