Task I: Write THREE independent programs in three SEPARATE directories: a key generation program, a sender’s program, and a receiver’s program, to implement ONE of the following options of simplified cryptographic applications. Option 1: Public-key encrypted message and its authentic digital digest • In this option, X is the sender and Y is the receiver. Option 2: symmetric-key encrypted message and its digital signature • In this option, X is the sender and Y is the receiver. Option 3: Digital envelope including keyed hash MAC the file “symmetric.key” should NOT be copied here from the directory “KeyGen”.) Task II: Test your programs on the Virtual Servers in the cloud. Task III: Present your work and demo your programs on the Virtual Servers in class. Show the outputs and the files generated by your programs as your programs run.
