How to run client_crypto and server_crypto: 

  Case 1: you are running client/server across two different machines: Set the UDP port with the -u option and the destination with the -d option. Example:

      On state.cs.rutgers.edu:  ./server_crypto -u 8888 -k server-keys.txt
      On null.cs.rutgers.edu: ./client_crypto -f test_file.txt -o ./foo.txt -d state.cs.rutgers.edu -k client-keys.txt -u 8888

  Case 2: you are running client/server on the same machine. Set the the local and remote UDP ports with the -l and and -r options. Note that between the client and server, the local and remote ports would be swapped. That is, the local port for the client would be the remote port for the server, and visa-versa. Set the destination with the -d option to the loopback IP address. Example:

     On one machine, in one window: 
       ./server_crypto -l 8888 -r 9999 -k server-keys.txt

     In a different window, on the same machine as above:
       ./client_crypto -f test_file.txt -o ./foo.txt -d localhost -k client-keys.txt -l 9999 -r 8888

  To generate a key-pair for use by the sodium cryptography library: 
    ./server_crypto -p
