WebHill Cipher encrypts a group of letters called a polygraph. This method makes use of matrices from mathematics. Encryption: The key and plaintext are converted into matrix format according to the positions like a=0 to z=25. The matrices are multiplied against modulo 26. The key matrix should have an inverse to decrypt the message. C = KP mod 26. WebJul 29, 2024 · Using Hill Cipher, Rubix Cube, Affine Cipher Algorithm to encrypt an image.

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. We want x * (-121) = 1 (mod 26). We can easily find ... WebJun 25, 2024 · Hill Cipher is a polygraphic substitution cipher based on linear algebra.
