WebA cypher is a message written in a secret code. Spies during World War II sometimes communicated using cyphers. WebIn cryptography, a classical cipher is a type of cipher that was used historically but for the most part, has fallen into disuse. In contrast to modern cryptographic algorithms, most classical ciphers can be practically computed and solved by hand. However, they are also usually very simple to break with modern technology.
