Whonix is an operating system focused on anonymity, privacy and security. It’s based on the Tor anonymity network, Debian GNU/Linux and security by isolation.
Whonix consists of two parts: One solely runs Tor and acts as a gateway, which we call Whonix-Gateway. The other, which we call Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible. With Whonix, you can use applications and run servers anonymously over the internet.
It is important to check the integrity of the virtual machine images you downloaded to make sure no man-in-the-middle attack or file corruption happened.
Whonix virtual machine images are cryptographically signed using OpenPGP by Whonix developer Patrick Schleizer.
