%description

WireGuard is an extremely simple yet fast and modern VPN that utilizes

state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more

useful than IPsec, while avoiding the massive headache. It intends to be

considerably more performant than OpenVPN. WireGuard is designed as a general

purpose VPN for running on embedded interfaces and super computers alike, fit

for many different circumstances.
