wireguard_py - A cython library allowing direct access to Wireguard kernel functions from Python
For most use cases, the Wireguard CLI is all one needs to set up a working Wireguard tunnel. However, for more complex scenarios (e.g. the creation and maintenance of a
Wireguard mesh involving many thousands of peers), using a high-level language to manage all of the peer configuration and monitoring make life much easier. The wireguard_py
cython module exists to make this possible in Python without the additional overhead and fragility of having to shell out to the wireguard CLI, as well as providing type hints.
Installing
Installation is performed via pip:
pip install wireguard-py
Using wireguard_py
An quick example of setting up a wireguard connection and peering:
import ipaddress
import pyroute2
import wireguard_py
from wireguard_py.wireguard_common import Endpoint
# Create the wireguard interface
ipr = pyroute2.IPRoute()
ipr.link("add", ifname="wg0", kind="wireguard")
wg_ifc = ipr.link_lookup(ifname="wg0")[0]
ipr.addr("add", index=wg_ifc, address="172.16.0.1", prefixlen=24)
ipr.link("set", index=wg_ifc, state="up")
# Configure wireguard interface
priv_key = wireguard_py.gen_priv_key()
wireguard_py.set_device(
device_name=b"wg0",
priv_key=priv_key,
port=51820,
)
# Create a peer
wireguard_py.set_peer(
device_name=b"wg0",
pub_key=b"lM77O8LlU4PNI0ZPWsTPYS3SGubG2/YT26uh9o9LKzM=",
endpoint=Endpoint(ip=ipaddress.ip_address("172.16.0.2"), port=51820),
allowed_ips={
ipaddress.ip_network("172.16.0.2/32"),
ipaddress.ip_network("10.0.0.0/8"),
},
replace_allowed_ips=True,
)
# List peers
peers = wireguard_py.list_peers(b"wg0")
print(peers)License
