Cryptography has been around for thousands of years. It has decided wars, and is at the heart of the worldwide communication network today. The fascinating story of cryptography requires us to understand two very old ideas related to number theory and probability theory. Transposition cipher | cryptology | Britannica Transposition cipher, simple data encryption scheme in which plaintext characters are shifted in some regular pattern to form ciphertext. In manual systems transpositions are generally carried out with the aid of an easily remembered mnemonic. For example, a popular schoolboy cipher is the “rail CryptoClub CryptoClub
