WebJun 3, 2024 · Cryptography is the science of using codes and ciphers to protect messages. And encryption involves encoding messages so that only the intended recipient can understand the meaning of the message. It's often used to protect data in transit. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as they are both a set of steps that encrypt a messag…
