http://practicalcryptography.com/ciphers/hill-cipher/ WebFor our example key matrix: So, modulo 26, the determinant is 25. Since this has no common factors with 26, this matrix can be used for the Hill cipher. The risk of the determinant having common factors with the modulus can be eliminated by making the modulus prime.
