How to test it with a real Lightning Network/Bitcoin wallet

1. Install Tor and configure Tor

sudo apt install tor
mkdir ~/hidden_service
sudo nano /etc/tor/torrc

2. Add two lines to your Tor config

HiddenServiceDir /home/your_username/hidden_service/
HiddenServicePort 80 127.0.0.1:5000

3. Restart Tor

sudo service tor restart

4. Clone this repository and install the dependencies

git clone https://github.com/ko-redtruck/ln-auth-python.git
cd /ln-auth-python
sudo pip3 install flask pyqrcode

5. Run Tor and get your hostname

tor

Go to your /hidde_service dir, open the file hostname and copy the onion address and replace the the address in app.py, line 21 with your own.

6. Run Flask

flask run

Open http://127.0.0.1:5000/auth in your web browser or your onion_address/auth in Tor and scan the QR-Code with a wallet that supports ln-auth.
