Wireguard Utilities

This is a helper module for creating configs for WireGuard VPN for both the server side and the client side.

Quick Start

Setup a WireGuard server:

from wireguard import Server

server = Server('myvpnserver.com', '192.168.24.0/24', address='192.168.24.1')

# Write out the server config to the default location: /etc/wireguard/wg0.conf
server.config.write()

Create a client within the previously created server:

peer = server.peer('my-client')

# Output this peer's config for copying to the peer device
print(peer.config.local_config)

# Rewrite the server config file including the newly created peer
server.config.write()

Create a standalone client:

from wireguard import Peer

peer = Peer('my-client', '192.168.24.0/24', address='192.168.24.45')

# Write out the peer config to the default location: /etc/wireguard/wg0.conf
peer.config.write()

Note: Both the server and peer config files are named the same by default. This is because they would typically be on different machines and would not interfere with one another. Be aware of this when generating peer configs on a server node, or on any node that has a pre-existing wireguard config at the default file location.

Other Features

You can also pass both the address and subnet in a combined way to Server:

# Set the subnet to 192.168.24.0/24 and the server's IP to 192.168.24.51
server = Server('myvpnserver.com', '192.168.24.51/24')

A custom JSON encoder is also provided: wireguard.utils.json.JSONEncoder. This can be used as the value for cls in any call to json.dumps(). As a convenience, it is used automatically by both peers and servers when using the .json() method. Any arguments provided are passed through to json.dumps():

server.json(sort_keys=True, indent=4)

which will output:

{
    "address": [
        "192.168.24.51"
    ],
    "allowed_ips": [
        "192.168.24.51/32"
    ],
    "description": "myvpnserver.com",
    "dns": [],
    "endpoint": null,
    "interface": "wg0",
    "keepalive": null,
    "mtu": null,
    "peers": [],
    "post_down": [],
    "post_up": [],
    "pre_down": [],
    "pre_up": [],
    "preshared_key": null,
    "private_key": "+ZNzpdQKgnuFHGtwDn3EzTZB5J8kYis+UMQ4FALSvtI=",
    "public_key": "AvteU+hwrtJW4QvDy/xH+rxXzNHQ33LclcQ646xwmFw=",
    "subnet": [
        "192.168.24.0/24"
    ],
    "table": null
}

Note: If you pass the cls argument to the Peer.json() method, it will override the use of the included custom JSON encoder. Therefore, you will have to handle the appropriate objects within the JSON encoder that is being passed.
