How to authenticate tor controller using password about tor-browser-selenium

[psivesely]

Do you want Tor Browser itself to authenticate to the control port or do you just want to be able to programmatically send the control port commands? I imagine in most scenarios you're automating the browser you'd want the latter. I believe the only control port command Tor Browser will send is NEWNYM and that is when you click "New Identity" in the Torbutton extension menu. You could do the same using stem.

As @fowlslegs mentioned, you need to use stem to authenticate to the Tor controller. Check this example: stem_adv.py. It uses the stem's authenticate method to which you can pass user and password.

I would use getpass if you want to interactively prompt for a password each time. Otherwise, setting CookieAuth 1 in your torrc is easier than using a password (alternatively you can not modify your torrc and instead pass a config keyword dict to stem.process.launch_tor_with_config with that option).

I'm already using stem with authentication to send commands programmatically.
I'm just wondering if I need to tell the Tor Browser the password when connecting to Tor when configured with a control password

You can set a password for the Tor controller by setting the HashedControlPassword option in the torrc that the TorBrowserDriver will use. Again, you can set that option programmatically by making use of stem (see the example).

I'm telling you, that's what I'm already doing. You didn't get what I'm asking.

I start a tor process using stem, and setting the option programmatically using steam (not torrc), and when I connect to the controller (also using stem and HashedControlPassword) I am authenticating correctly.

Now I want to run the tor browser and connecting it to that tor process (Socks doesn't need password, I know that), but I was wondering if I also need to tell the Tor browser (and specifically Tor button) the password for the controller. Probably I don't really need to, as I'm sending commands only using stem

[Zorgatone]

Using TorBrowserDriver(tor_cfg=cm.USE_RUNNING_TOR) will be enough, or is there a password parameter to it?

[mjuarezm]

Yes, that's should be enough. The TorBrowserDriver does not talk to the Tor controller.

No. That's not necessary unless you plan on driving Selenium to click the TB UI buttons that would send control port commands, such as "New Identity." Since there's no point in doing such a thing when you can send the same command with stem programmatically, you should be able to just use it as a socks proxy without authenticating to the control port. The only use I could see for authenticating is if you were trying to functionally test the Tor Browser itself.

Oh, I see. Ok.
Thanks!
