Webcipher: A cipher (pronounced SAI-fuhr ) is any method of encrypting text (concealing its readability and meaning). It is also sometimes used to refer to the encrypted text message itself although here the term ciphertext is preferred. Its origin is the Arabic sifr , meaning empty or zero . In addition to the cryptographic meaning, cipher also ... WebMay 1, 2024 · Cryptography, at its most basic, is the science of using codes and ciphers to protect messages. Encryption is encoding messages with the intent of only allowing the intended recipient to understand the meaning of the message. It is a two way function (you need to be able to undo whatever scrambling you’ve done to the message).
