Problem 2. Implement the same Playfair Cipher from P1. Both encryption and decryption are required. This implementation is required to work on letters only. (You can use numbers, e.g., ASCI for the actual computation.) All letters are processed in upper-case forms. Neglect the spaces between words. a. The key matrix shall be created automatically with a keyword e.g., "CINCINNATI" b. The key word can be changed easily in your program. c. Encrypt the message "A TEST TO ENCRYPT USING PLAYFAIR CIPHER", with the keyword "CINCINNATI Decrypt your cipher text. d. Matlab is recommended, but you can choose whatever language you prefer.
