virtualx-engine/platform/javascript/export/export.cpp
Fabio Alessandrelli c9dcf2b37b [HTML5] HTTP server uses optional SSL. 
Generates a key/cert snakeoil pair or use a custom SSL cert/key.
This is of course false security, and potentially detrimental for it.

But, so long, those are the requirements browser vendors agreed on to
use things like the Gamepad API, and more advanced topics like wasm
threads.

You don't need this if you run on localhost (at least!), but you do
need this (or a much safer nginx proxy) to try those things on your
local network (e.g. when debugging a phone, networking, etc).
