Atbash Cipher Tutorial
What is the Atbash Cipher?
The Atbash cipher is a simple substitution cipher where the alphabet is reversed. The first letter (A) is swapped with the last letter (Z), the second (B) with the second-to-last (Y), and so on.
How it Works
To encrypt a message, you simply replace each letter with its reverse. To decrypt, you do the exact same thing!
The Atbash Alphabet:
Plain: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Cipher: Z Y X W V U T S R Q P O N M L K J I H G F E D C B A
For example, "HELLO" becomes "SVOOL".
