WebI'm new to cryptography and I cannot seem to get my head around this problem: The problem says that the Hill Cipher using the below 2 x 2 key matrix (K) was used to produce the ciphered text "KCFL". K = (3 5) (2 3) It then asks to use the Hill Cipher to show the calculations and the plain text when I decipher the same encrypted message "KCFL". http://practicalcryptography.com/ciphers/hill-cipher/
