http://practicalcryptography.com/ciphers/hill-cipher/ my little pony the gameWebIn the Hill Cipher, the number of components in the vector (that you note n) is not usually the same as the modulus you set at 26. n = 3 is typical, and makes the padding issue less relevant. Notice that the cipher is slightly less vulnerable if the modulus is prime. – fgrieu ♦ Oct 27, 2014 at 15:34 Add a comment 1 Answer Sorted by: 2 my little pony theme 1 hourWebThe inverse of matrix K for example is (1/det (K)) * adjoint (K), where det (K) <> 0. I assume that you don't understand how to calculate the 1/det (K) in modulo arithmetic and here is where linear congruences and GCD come to play. Your K has det (K) = -121. Lets say that the modulo m is 26. We want x * (-121) = 1 (mod 26).
