A pure python Tor client implementation of the Tor protocol. Torpy can be used to communicate with clearnet hosts or hidden services through the Tor Network.

Features

  • No Stem or official Tor client required
  • Support v2 hidden services (v2 specification)
  • Support Basic and Stealth authorization protocol
  • Provide simple TorHttpAdapter for requests library
  • Provide simple urllib tor_opener for making requests without any dependencies
  • Provide simple Socks5 proxy

Console examples

There are several console utilities to test the client.

A simple HTTP/HTTPS request:

$ torpy_cli --url https://ifconfig.me --header "User-Agent" "curl/7.37.0"

Usage examples

A basic example of how to send some data to a clearnet host or a hidden service:

from torpy import TorClient

hostname = 'ifconfig.me'  # It's possible use onion hostname here as well
with TorClient() as tor:
    # Choose random guard node and create 3-hops circuit
    with tor.create_circuit(3) as circuit:
        # Create tor stream to host
        with circuit.create_stream((hostname, 80)) as stream:
            # Now we can communicate with host
            stream.send(b'GET / HTTP/1.0\r\nHost: %s\r\n\r\n' % hostname.encode())
            recv = stream.recv(1024)

TorHttpAdapter is a convenient Tor adapter for the requests library. The following example shows the usage of TorHttpAdapter for multi-threaded HTTP requests:

from multiprocessing.pool import ThreadPool
from torpy.http.requests import tor_requests_session

with tor_requests_session() as s:  # returns requests.Session() object
    links = ['http://nzxj65x32vh2fkhk.onion', 'http://facebookcorewwwi.onion'] * 2

    with ThreadPool(3) as pool:
        pool.map(s.get, links)

For more examples see test_integration.py

Installation

  • Just pip3 install torpy
  • Or for using TorHttpAdapter with requests library you need install extras: pip3 install torpy[requests]
