RuWireGuard-Go

This is a reference implementation of the Ru-WireGuard protocol in Go.

Ru-WireGuard-Go is a WireGuard-Go fork.

It has the same semantics as the original WireGuard protocol but employs the cryptographic algorithms defined by the Russian national standards (GOST).

Warnings

• Maturity: The code is experimental. You must not use this in production
• Audit: The code is not audited
• Stability: Breaking changes are expected
• Performance: elliptic curve and MGM implementations are extremely slow

Goals

At the present time, the main goal of the project is to provide an implementation of the core protocol with GOST primitives. Formal verification, high-performance and stable cross-platform usage are out of the scope.

Dependencies

RuWireGuard-Go relies on the following packages:

• GoGOST
• GOSThopper

Quickstart

Build

make

Test

make gotest

Protocol Benchmark

Usage

Most Linux kernel WireGuard users are used to adding an interface with ip link add wg0 type wireguard. With wireguard-go, instead simply run:

$ wireguard-go wg0

This will create an interface and fork into the background. To remove the interface, use the usual ip link del wg0, or if your system does not support removing interfaces directly, you may instead remove the control socket via rm -f /var/run/wireguard/wg0.sock, which will result in wireguard-go shutting down.

To run wireguard-go without forking to the background, pass -f or --foreground:

$ wireguard-go -f wg0

When an interface is running, you may use wg(8) to configure it, as well as the usual ip(8) and ifconfig(8) commands.

To run with more logging you may set the environment variable LOG_LEVEL=debug.

Platforms

Linux

This will run on Linux; however you should instead use the kernel module, which is faster and better integrated into the OS. See the installation page for instructions.

macOS

This runs on macOS using the utun driver. It does not yet support sticky sockets, and won't support fwmarks because of Darwin limitations. Since the utun driver cannot have arbitrary interface names, you must either use utun[0-9]+ for an explicit interface name or utun to have the kernel select one for you. If you choose utun as the interface name, and the environment variable WG_TUN_NAME_FILE is defined, then the actual name of the interface chosen by the kernel is written to the file specified by that variable.

Windows

This runs on Windows, but you should instead use it from the more fully featured Windows app, which uses this as a module.

FreeBSD

This will run on FreeBSD. It does not yet support sticky sockets. Fwmark is mapped to SO_USER_COOKIE.

OpenBSD

This will run on OpenBSD. It does not yet support sticky sockets. Fwmark is mapped to SO_RTABLE. Since the tun driver cannot have arbitrary interface names, you must either use tun[0-9]+ for an explicit interface name or tun to have the program select one for you. If you choose tun as the interface name, and the environment variable WG_TUN_NAME_FILE is defined, then the actual name of the interface chosen by the kernel is written to the file specified by that variable.
