This is a simple and minimalistic Python3 script for User:Password authentication in OpenVPN.

The Users and Passwords are appended manually to a Htaccess formed file. Passwords must be hashed with bcrypt(12).

Upon an incoming Connection, OpenVPN will check the provided credentials with the script and the Htaccess formed file.

• Read Htaccess formed File
• Check Bcrypt hased passwords
• Log events into stdout so they get persisted in the OpenVPN Logs

• Python3
• Bcrypt Library for Python3

sudo yum install python34 python34-pip sudo pip3 install bcrypt 

sudo dnf install python3 python3-pip sudo pip3 install bcrypt 

sudo apt-get update sudo apt-get install python3 python3-pip sudo pip3 install bcrypt 

1. Download auth.py and user.data from releases
2. Copy auth.py and user.data in the Folder /etc/openvpn/
3. Check file permissions! It should owned by root, 755 for auth.py and 644 for user.data

Generate Passwords on http://aspirine.org/htpasswd_en.html , with bcrypt(12)! Append the generated lines to user.data
