Authentifizieren eines Controllers mit einem Tor-Subprozess mit Hilfe von Stamm

Question

Ich versuche, einen neuen tor-Prozess (keine laufenden Prozesse auf dem System) mit einer benutzerdefinierten Konfiguration unter Verwendung von Stems launch_tor_with_config zu starten.

Ich schrieb eine Funktion, die erfolgreich ein neues Hash-Passwort generieren und erfassen wird. Ich benutze dann dieses neue Passwort in der Config, starten Tor und versuchen, mit dem gleichen Passhash authentifizieren und es schlägt fehl. Hier

ist der 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) 

Dies ist, was passiert, wenn ich den obigen Code auszuführen:

Bin ich etwas fehlt?

Das Problem ist, dass Sie mit dem Kennwort Hash statt das Kennwort selbst authentifizieren. Versuchen Sie ...

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

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