Atbash

Cryptography has historical backgrounds that can be traced back to the times when characters were created and messages had to be transmitted. And this period can certainly be dated to several thousand years BC.

One of the oldest encryption methods is Atbash, which indicates a Jewish background. It was a substitution c ipher in which the characters were ciphered in reverse alphabetical order. Thus, the letters "A" were substituted by "Z", "B" by "Y", "C" by "X", and so on.
