autotor 2.0.0

AutoTor is a simple package to make requests through Tor. It allows automation, easy Tor circuit renewal and customisation of the requests in a threaded way.

About the Project

Simple high-level API to make parallel requests throughout Tor in an automated way, with circuit renewal and randomised user-agents. It can be used to easily navigate in an anonymus way or to get information from webs. At the moment, AutoTor is not OS-agnostic as it is tailored to Windows but is expected to become compatible with, at least, Linux in the short-term.

Contents

The most important source code elements in the project are outlined and described as follows:

• main.py: Implements an example of how the library should be used.
• AutoTor module:
  • autotor_base.py: Implements a class that takes care of all the logic to automate Tor download, Tor configuration, Tor initialisation, getting request sessions, Tor circuit renewal, releasing Tor resources and performing parallel runs with a pool of threads.
  • autotor_ip.py: Implements an example class to override the request function that actually takes care of the requests. In this case, the function tries to get the IP in use by Tor.

Coding

Create your class

The main class of the package is TorRequests. It is a class with an abstract method request that should be implemented in any derived class to customise the request as desired by the user. TorIP is an example class illustrating how the derived class could be potentially implemented. Below is the metacode for a sample implementation:

from autotor import TorRequests
from threading import Lock

GLOBAL_LOCK = Lock()

class MyClass(TorRequests):

    # Override the initialisation function (if needed).
    def __init__(self, another_arg = 5, *args, **kwargs):
        # Initialise superclass.
        super(MyClass, self).__init__(*args, **kwargs)
        # Initialise other parameters.
        self.another_arg = another_arg

    # Override the request function and implement custom functionality. 
    # This function gets as inputs the elements the current thread should 
    # take care of and the ID of the current thread. Naturally, the 
    # function should be thread-safe.
    def request(self, elem, n_id):
        
        # Get Tor session.
        session = self.get_tor_session(n_id)
        # Renew Tor circuit.
        self.renew_tor_ip(n_id)

        # Use the session to get information.
        # Use elem to characterise the differences between requests.
        # Use GLOBAL_LOCK to handle non-atomic operations.
        ...

Note: In order to make the requests with another IP and user-agent just get another session and call the renew method. It is also recommended to randomise the waiting time between requests.

Usage

Once one has implemented the request method in the derived class, one can use the threaded request version within a with statement to implicitly call the request method. Any opened resources will be automatically cleared upon exiting the statement.

from autotor import MyClass
import numpy as np

# Use threaded_request within a with statement. This function will 
# take care of allocating the list of requests among the thread pool.
with MyClass(another_arg = 20, n_process = 5, tor_root = ".") as tor:
    result = tor.threaded_request(np.arange(10))
