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: bitcoin green address daryl pfister ophthalmologyWebFirst we choose a key matrix of any size that is invertible, square, and contains nonnegative integers.
