"WebHill Cipher encrypts a group of letters called a polygraph. This method makes use of matrices from mathematics. Encryption: The key and plaintext are converted into matrix format according to the positions like a=0 to z=25. The matrices are multiplied against modulo 26. The key matrix should have an inverse to decrypt the message. C = KP mod 26. " - Hill cipher in cpp
