Pretty cool. Have you seen considerations regarding port knocking by Moxie Marlinspike? I think he raises some valid points: https://github.com/moxie0/knockknock
Instead of using UDP he reads the firewall log. Also he prevents replay attacks (even though his implementation is apparently not secure in this regard). Unfortunately his code is ancient and in Python 2, so a rust implementation would be awesome.
