Hill 2x2 example

This is a JavaScript implementation of the Hill Cipher. The case here is restricted to 2x2 case of the hill cipher for now, it may be expanded to 3x3 later. The 'key' should be input as 4 numbers, e.g. 3 4 19 11. These numbers will form the key (top row, bottom row). key = Ciphertext See more Invented by Lester S.
