To that … 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 … See more Originating from the Arabic word for zero صفر (sifr), the word “cipher” spread to Europe as part of the Arabic numeral system during the Middle Ages.
