WebSymmetric ciphers are commonly used to achieve other cryptographic primitives than just encryption. [citation needed] Encrypting a message does not guarantee that it will remain unchanged while encrypted. Hence, often a message authentication code is added to a ciphertext to ensure that changes to the ciphertext will be noted by the receiver. WebCodes generally operate on semantics, meaning, while ciphers operate on syntax, symbols. A code is stored as a mapping in a codebook, while ciphers transform individual symbols according to an algorithm. Now, …
