The Atbash Cipher is a tool that can be used to hide information/send secret messages to people. Below is the Atbash Cipher:

                      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
                      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

Basically, the cipher uses a reverse alphabet, so you subject a letter for it's corresponding reverse.

Examples

"HELLO" would become "SVOOL", "CHAIR" would become "XSZRI", "TELEVISION" would become "GVOVERHRLM".

One could save time by cutting the cipher in half, so it appears like this:

                                    A B C D E F G H I J K L M
                                    Z Y X W V U T S R Q P O N
