IIRC (it's been a few years since I worked on OpenStack at this point), the plan (which I had partially implemented) was a kind-of mitm proxy that set up the security by doing the initial handshake with security to the server, then faking a no-security handshake based on that with the client. Install ttf-dejavu. That should protect you from eavesdropping, yes. How can we create psychedelic experiences for healthy people without drugs? This file contains commands that are executed automatically when we start or restart the VNC server. So if the network is otherwise secure against eavesdropping, then encryption doesn't really add any extra security.
