Digraph Cipher

Digraph Cipher

The Digraph Cipher is kind of like the Vigenere Cipher. When you write a sentence you would write it in pairs of twos, li ke th is, and if there is a letter left over add an x to it. The pairs of letters will be the coordinates for the two letters. An example would be "IA MT RY IN GT OE XP LA IN TH IS" = "VG ZN EI VT TN BC KR YG VT GZ VO". To decipher it the decoded letters will be the coordinates.
