WebSep 28, 2024 · Hill Cipher 3×3 example. Now we will take an example for a 3×3 matrix for encryption, using the input message ‘retreat now’. Here the key phrase is given as BACK … WebThe matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible n× nmatrices (modulo26). The cipher can, of course, be adapted to an alphabet with any number of letters; all arithmetic just needs to be done modulo the number of letters instead of modulo 26.
