A book cipher is a method of encryption and decryption that employs a physical book or text as the key. In this technique, secret messages are concealed by referencing specific words or passages from the book to encode and decode information. To encrypt a message, each word in the plaintext is replaced with a corresponding word or phrase found at a predetermined location within the chosen book.
