WebThe Hill cipher was the first cipher purely based on mathematics (linear algebra). To encipher a message, first the plaintext is broken into blocks of n letters which are converted to numbers, where A=0, B=1, C=2 ... Y=24, Z=25 (so each character is assigned to a number which is usually from the range of 00-25 for the characters A-Z. Upper case ...
