Yes, the final version will most certainly be using TLS or ssh. This
was just a proof of concept to validate our
code would work on windows.

Here is the log of my execution run. Looks like there was an error on
the socket, but nothing useful came back. I have also attached a
tcpdump log of the network traffic
to show it is the client end(192.168.1.10) issuing the reset after
receiving some data from the server (192.168.1.113)
``` Execution log
