OpenVPN Configuration and Encryption Information

Tunnelblick is a Graphic User Interface (GUI) for OpenVPN on OS X and macOS. It includes everything you need to run an OpenVPN client or server except OpenVPN configuration and encryption information.

The Tunnelblick project does not supply OpenVPN configuration and encryption information. That information must be supplied by the person or organization that is providing VPN services (your "VPN service provider"). If you are providing your own VPN services, you need to create the OpenVPN configurations and encryption information yourself.

The Tunnelblick website does not supply detailed information about how to set up a VPN, OpenVPN configurations, or the encryption information needed for a VPN; that information is readily available on the Internet.

OpenVPN Configuration

OpenVPN is an extremely flexible (and complex) program. It includes hundreds of options. The options to be used for a specific VPN are contained in an OpenVPN configuration file (a plain text file with an extension of ".ovpn" or ".conf"). Search the Internet to find out how to set up a VPN and create OpenVPN configuration files.

Encryption Information

Most VPNs use encryption to safeguard network traffic from eavesdroppers and man-in-the-middle attacks. To do that, OpenVPN needs encryption information in the form of keys, certificates, usernames, and passwords. These are not included in Tunnelblick. They are created by the person or organization that is supplying VPN services (the "VPN service provider"). If you are your own VPN service provider, you can follow OpenVPN's instructions for creating a Public Key Infrastructure (PKI).
