Digraph Cipher Tools.
Code or ciphertext MUST be in upper case and blocks of two before you press encipher or decipher.
Make sure that you have generated your cipher before trying to encipher or decipher with it. Encipherement occurs by finding the plaintext letter pair in the digraph grid and then finding the x-Coordinate and y-Coordinate letters corresponding to it. These letters then form the cipher text( x first then y) To decipher work in reverse. Use the first letter of the ciphertext pair as the x-coordinate and the second letter as the y-coordinate this then gives the plaintext letter pair.
