Hill cipher Decryption: Every letter has corresponded with a unique number. For decrypting a message, each block needs to be multiplied by the inverse matrix in parallel with mod 26. Formula: D (K,C)= (K^-1*C)mod 26.

WebPlease answer only in C++ Programming. Hill cipher: 3. Implement functions to perform encryption/decryption with 2x2 Hill Cipher. The key should be an invertible matrix over the integers mod 26. a. Show the output of your encrypt function on the following (key, plaintext) pair: b. K = (9 13 2 3), ciphertext = 'YIFZMA.'. 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.
