The results are then converted back to letters and the ciphertext message is produced. Here's a quick tutorial to help you better understand the Hill Cipher by using matrices. This article do not cover algorithm behind the Hill cipher. Copy Link. Please leave any questions or comments in … Comments. Each block of plaintext letters is then converted into a vector of numbers and is dotted with the matrix. For decryption of the ciphertext message the inverse of the encryption matrix must be fo;; In classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. MugdhaSK. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. The Hill Cipher uses an area of mathematics called Linear Algebra, and in particular requires the user to have an elementary understanding of matrices.It also make use of Modulo Arithmetic (like the Affine Cipher).Because of this, the cipher has a significantly more mathematical nature than some of the others.
