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. http://practicalcryptography.com/ciphers/hill-cipher/ elevation screw
