Donenfeld +endef + +define Package/wireguard/Default/description + WireGuard is a novel VPN that runs inside the Linux Kernel and 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.
