Correct, it will be in the dark net. And it’s as secure as your web server. So I guess if your web server is set up in a very insecure manner, it would be very insecure as well. But since nobody would know the onion address besides you or anybody you give it to, it should be all right.
I mean, it’s obviously the only solution, right? You don’t have to pay for a domain name. You don’t have to pay for a hosted IP address. You don’t have to forward ports. You don’t have to do any of that shit. Plus, you’re on the darknet, and everything should be on the darknet. All the time.
