I was paying $385 per month in gas for an Astra hatchback, which is not exactly a gas guzzler, though I did live in the mountains at the time.

I replaced it with a Bolt EV and the hit to my electric bill was about $50 with the same commute.

Or just use Nginx stream proxy, and all the encryption happens on the endpoints. No need for certs on the proxy at all.

This is how I make https and mqtts available on ipv4.
