WebOutput example of the Hill cipher implementation Advantages of Hill cipher. The main advantage of the Hill cipher is that it hides single letter frequency. Depending on how big the matrix that represents the key is, the more letter frequency it hides. For instance, if you use a 3×3 matrix, it hides single letter and two-letter frequencies. WebWhat makes the Hill cipher a block cipher is that each plaintext string is encrypted “at once:” the change of one letter in a plaintext block is likely to change all of the letters in the ciphertext block. Notice, for example, that changing the plaintext block he to ie changes the ciphertext block from GV to JA.

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). ehefrau jerome boateng
