Bitmask is an open source application to provide easy and secure encrypted communication with a VPN. You can choose among different providers or start your own.
So basically this is a interface for a VPN. I downloaded it, created an account with the https://calyx.net/ service and I was ready to use a VPN. I consider creating an account with calyx.net a microtrade, since you can just type in any username. Plus no trackers and ads on the website.
