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.
