WebThe encryption key for a Hill cipher is a square matrix of integers. These integers are taken from the set {0,1,...,n − 1}, where n is the size of the character set used for the plaintext message. (If this is the usual English alphabet, then n = 26.) It is important to note that not all such square matrices are valid keys for a Hill cipher.
