Need a program that implements the playfair cypher. Should have a menu with 3 options 1.Encrypt, 2. Decrypt and 3.exit. The program should first prompt a user to enter a key. Then it takes them to the menu and they can choose one of the 3 options

If they select encrypt, program should ask the user to enter a message. Program should return the message in cypher text 

If they select decrypt, the user should be allowed to enter the cypher text and have it be converted to the message
