I wanted to visit .onion sites without using tor. Because tor speed is very slow. Can i access tor sites using vpn-proxies? And what types of proxies i need to use? is it is HTTP/SOCK4/5? Or all types of vpn-proxies support darknet access? i dont aware about my security. encryption doesn't matter, If speed is better.
You can access .onion sites only using Tor.
Those a hosted within Tor and cannot be accessed without using Tor.
Or you can access tor using https://tor2web.org/ if you don't care about anonymity.
Also take a look at this: https://www.torproject.org/docs/hidden-services
Its explains how does hidden services works.
