WebThe Playfair cipher is a multiple letter encryption cipher that uses a substitution technique. The steps to implement it are as follows: Create a 5×5 matrix using the secrete key. In this matrix, I and J are in the same cell. you start filling the matrix with the key, then you use the alphabet. Letters are placed only once in the matrix. WebI know with other matrices, e.g. for the determinant there is usually a formula, such as: a x d - b x c. However, for the Hill Cipher I am completely lost. I have done the following: a) found …

The determinant of the matrix we are inverting is ac - bd (mod 26) = 15*19 - 12*2 = 261 = 1 (mod 26). We also need to find the inverse of the determinant (1), which luckily in this case is 1 because 1 is its own inverse. canned cream of mushroom soup recipes
