How to set up a Tor-Server (Hidden Service) as a proxy?

Question

The goal is, being able to access the proxy anonymously, such that the host (proxy) doesn’t know, where the request came from (of course with credentials).

The client should be able to acess www.example.com over the hosts ip, without the host knowing the clients ip.

Here’s a example request route to www.example.com:

How would I hookup a browser to it?
How would I connect using Python? (something proxy-chain like?)

Note: OS doesn’t depend, programming language preferably Python

EDIT:

The Client in my case should be able to specify:
- Headers
- request-method
- site-url
For the request which the hidden-service makes (so basically a proxy)

Answer 1

To use a Tor hidden service as a proxy, you must install Tor on the server. https://www.torproject.org/download/ has the programme.

After installing Tor, add these lines to your torrc file:

import socks
import socket

socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 9050)
socket.socket = socks.socksocket

# Use the socket module normally, and all connections will go via the proxy.

To utilise the tor hidden service with a browser, set the browser to use the Tor SOCKS proxy on localhost:9050 and use the hidden service hostname for the target address, which can be found in the file titled "hostname" in HiddenServiceDir.

The python-stem library can automate starting and stopping the tor service, establishing and deleting hidden services, and getting the hidden service’s onion address.

first you need to create a hidden service on tor from host to be able to communicate over tor network

basic flask proxy example (for more advanced proxy you can follow this code):

from stem.control import Controller
from requests import get
from flask import Flask

SITE_NAME = 'https://google.com/'

if __name__ == "__main__":

    app = Flask("example")
    port = 5000
    host = "127.0.0.1"
    hidden_svc_dir = "c:/temp/"

    @app.route('/', defaults={'path': ''})
    @app.route('/<path:path>')
    def proxy(path):
        return get(f'{SITE_NAME}{path}').content
    controller = Controller.from_port(address="127.0.0.1", port=9151)
    try:
        controller.authenticate(password="")
        controller.set_options([
            ("HiddenServiceDir", hidden_svc_dir),
            ("HiddenServicePort", "80 %s:%s" % (host, str(port)))
            ])
        svc_name = open(hidden_svc_dir + "/hostname", "r").read().strip()
        print "onion link: %s" % svc_name
    except Exception as e:
        print e
    app.run()

after runing this you will get a onion link like: "somelongstringwithnumber123.onion" with that onion link you can connect to host from client over tor network

Than you need to make request over tor network from host:

import requests

session = requests.session()
session.proxies = {}
session.proxies['http'] = 'socks5h://localhost:9050'
session.proxies['https'] = 'socks5h://localhost:9050'

r = session.get("http://somelongstringwithnumber123.onion")
print(r.text)

im not gonna test that codes but i hope you understand the main idea.
