WebThe Atbash Cipher is a really simple substitution cipher that is sometimes called mirror code. It is believed to be the first cipher ever used, and its use pre-dates Egyptian examples of encryption. To use Atbash, you simply reverse the alphabet, so A encodes to Z, B to Y and so on.

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. The Roman numeral system lacked the concept of zero, and this limited advances in mathematics. In this transition, the word was adopted into Medieval Latin as cifra, and then into Middle French as cifre. This eventually led to the English word cipher (minority spelling cypher).
