Running Key Cipher: A type of cipher that uses a long, pre-determined piece of text (known as the “key”) to encrypt and decrypt messages. It is used in cryptography to encode and decode secret messages. Examples of running key cipher include using a book as the key to encrypt a message or using a string of random numbers as the key to decrypt a message.
