OpenVPN is used to creating network tunnels between computers that are not on the same local network. When integrated with OpenSSL, OpenVPN can encrypt all VPN traffic to provide a secure connection between machines.
A common use case for a VPN tunnel is to access the internet from behind it to evade censorship or geolocation and protect your connection from untrusted internet service providers, WiFi hotspots, and sites and services you connect to.
This guide will show you how to install, configure and fine-tune OpenVPN clients on Android, iOS, Linux, OS X and Windows.
