使用 Stem 对带有 Tor 子进程的控制器进行身份验证

Question

我正在尝试使用 'custom' 配置启动一个新的 tor 进程（目前系统上没有 tor 进程运行ning）launch_tor_with_config.

我编写了一个函数，可以成功生成并捕获新的散列密码。然后我在配置中使用该新密码，启动 tor 并尝试使用完全相同的 passhash 进行身份验证，但失败了。

代码如下：

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)

这是当我运行上面的代码时发生的情况：

我是不是漏掉了什么？

问题在于您是使用密码哈希而不是密码本身进行身份验证。尝试...

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

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

使用 Stem 对带有 Tor 子进程的控制器进行身份验证
