Good to know about this tool

What does this tool do?

Creates an OpenVPN client configuration file (.ovpn) as a template with the chosen connection and encryption settings.

Why does it exist?

Because manually writing an OpenVPN configuration with correct cipher syntax is error-prone.

Typical use cases

Create a quick starting point for a new .ovpn file
Migrate an existing configuration to modern ciphers
Understand the configuration structure for training purposes

Best practices & notes

Use AES-256-GCM instead of outdated ciphers like BF-CBC
Use tls-auth/ta.key for additional HMAC protection against DoS attacks
Never send certificates unencrypted via email

Frequently Asked Questions

Where do I get the certificates?

Certificates are generated by the OpenVPN server (or its PKI/Easy-RSA setup) and must be transferred separately and securely.

Is my data transmitted?

No, the configuration is assembled entirely locally in the browser.
