WebJan 15, 2016 · So I am trying to use the hill cipher to encrypt my 3x3 matrix with a given key. It works correctly for the first value outputting n which it should, but then after that value I get large values and it never takes the mod of them. I added the cout statements to help me debug and see what's going wrong, but I still can't fix it. WebThe Hill cipher is a polygraphic substitution cipher based on linear algebra. It was the first polygraphic cipher in which it was practical to operate on more than three symbols at …
