Web4-Hill cipher: Hill cipher is a multiletter cipher . The encryption algorithm takes m successive plaintext letters and substitutes for them m ciphertext letters. The substitution is determined by m linear equations in which each character is assigned a numerical value (a = 0, b = 1 ... z = 25). For m = 3, the system can be described as follows: http://practicalcryptography.com/ciphers/hill-cipher/

Webreason, as the dimension of the key matrix increases, the more secure the Hill Cypher becomes. For perspective, for an NxN matrix using our encryption example, there are 26𝑁2 possibilities. So, for a 2x2 matrix, that provides over 456,000 unique matrices, while a simple increase to a 3x3 matrix can provide of 5 trillion unique matrices.
