WebThe 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. WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra.Invented by Lester S.
