BoringTun is an implementation of the WireGuard® protocol designed for portability and speed.
The project consists of two parts:
boringtun, a userspace WireGuard implementation for Linux and macOS.
boringtunthat can be used to implement fast and efficient WireGuard client apps on various platforms, including iOS and Android. It implements the underlying WireGuard protocol, without the network or tunnel stacks, those can be implemented in a platform idiomatic way.
⚠️ NOTE: This crate is still undergoing review for security concerns. Therefore, we recommend that you take caution before using it in a production application.
You can install this project using
cargo install boringtun
cargo build --lib --release [--target $(TARGET_TRIPLE)]
cargo build --bin boringtun --release [--target $(TARGET_TRIPLE)]
By default the executable is placed in the
./target/release folder. You can copy it to a desired location manually, or install it using
cargo install --bin boringtun --path ..
As per the specification, to start a tunnel use:
boringtun [-f/--foreground] INTERFACE-NAME
The tunnel can then be configured using wg, as a regular WireGuard tunnel, or any other tool.
It is also possible to use with wg-quick by setting the environment variable
boringtun. For example:
sudo WG_QUICK_USERSPACE_IMPLEMENTATION=boringtun WG_SUDO=1 wg-quick up CONFIGURATION
Testing this project has a few requirements:
sudo: required to create tunnels. When you run
cargo testyou’ll be prompted for your password.
apt-get install docker.io.
To benchmark this project you can run this command:
cargo +nightly bench
This command depends on the unstable
test feature of the Rust compiler. As a result, you’ll need to use the
nightly channel of Rust when you run it.
Other platforms may be added in the future
armv7 architectures are supported. The behaviour should be identical to that of wireguard-go, with the following difference:
boringtun will drop privileges when started. When privileges are dropped it is not possible to set
fwmark is required, such as when using
wg-quick, instead running with
sudo, give the executable the
CAP_NET_ADMIN capability using:
sudo setcap cap_net_admin+epi boringtun. Alternatively run with
--disable-drop-privileges or set the environment variable
The behaviour is similar to that of wireguard-go. Specifically the interface name must be
utun[0-9]+ for an explicit interface name or
utun to have the kernel select the lowest available. 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.
