[$] Virtual private networks with WireGuard

Virtual private networks (VPNs) offer a lot in the way of increasedsecurity and privacy. They have also tended to offer less desirablefeatures like administrative complexity and reduced performance, though; asa result, many potential VPN users decide not to bother. A relatively newproject called WireGuard hopes toaddress both of those problems with an in-kernel solution that is bothsimple and fast.
