Authentification d'un contrôleur avec un sous-processus Tor en utilisant Stem

Question

J'essaye de lancer un nouveau processus tor (no tor processus actuellement en cours d'exécution sur le système) en utilisant une config «personnalisée» en utilisant des souches launch_tor_with_config.

J'ai écrit une fonction qui va générer et capturer avec succès un nouveau mot de passe haché. J'utilise ensuite ce nouveau mot de passe dans la configuration, le lancement et essaye de m'authentifier en utilisant le même passage et il échoue.

Voici le code:

from stem.process import launch_tor_with_config 
from stem.control import Controller 

from subprocess import Popen, PIPE 
import logging 

def genTorPassHash(password): 
    """ Launches a subprocess of tor to generate a hashed <password>""" 
    logging.info("Generating a hashed password") 
    torP = Popen(['tor', '--hush', '--hash-password', str(password)], stdout=PIPE, bufsize=1) 
    try: 
     with torP.stdout: 
      for line in iter(torP.stdout.readline, b''): 
       line = line.strip('\n') 
       if not "16:" in line: 
        logging.debug(line) 
       else: 
        passhash = line 
     torP.wait() 
     logging.info("Got hashed password") 
     logging.debug(passhash) 
     return passhash 
    except Exception as e: 
     logging.exception(e) 



def startTor(config): 
    """ Starts a tor subprocess using a custom <config> 
    returns Popen and controller 
    """ 
    try: 
     # start tor 
     logging.info("Starting tor") 
     torProcess = launch_tor_with_config( 
      config=config, # use our custom config 
      tor_cmd='tor', # start tor normally 
      completion_percent=100, # blocks until tor is 100% 
      timeout=90, # wait 90 sec for tor to start 
      take_ownership=True # subprocess will close with parent 
      ) 
     # connect a controller 
     logging.info("Connecting controller") 
     torControl = Controller.from_port(address="127.0.0.1", port=int(config['ControlPort'])) 
     # auth controller 
     torControl.authenticate(password=config['HashedControlPassword']) 
     logging.info("Connected to tor process") 
     return torProcess, torControl 

    except Exception as e: 
     logging.exception(e) 


if __name__ == "__main__": 
    logging.basicConfig(format='[%(asctime)s] %(message)s', datefmt="%H:%M:%S", level=logging.DEBUG) 
    password = genTorPassHash(raw_input("Type something: ")) 

    config = { 
     'ClientOnly': '1', 
     'ControlPort': '9051', 
     'DataDirectory': '~/.tor/temp', 
     'Log': ['DEBUG stdout', 'ERR stderr' ], 
     'HashedControlPassword' : password } 

    torProcess, torControl = startTor(config) 

Ce qui se passe quand je lance le code ci-dessus:

Est-ce que je manque quelque chose?

Answer 1

Le problème est que vous vous authentifiez avec le hachage du mot de passe plutôt qu'avec le mot de passe lui-même. Essayez ...

password = raw_input('password: ') 
password_hash = genTorPassHash(password) 

... then use the password_hash in the config and password for authentication
