wg-request

a tool to help you with wireguard client peer provisioning, exchanges public keys and kinda manages IP addresses
join-wg.sh -- client side bash wrapper/helper
wg-request -- the tool. python script. handles both client and sever side

Usage

TLDR:

# on the server:
curl -Ls https://raw.githubusercontent.com/greyltc-org/wg-request/master/wg-request | python3 - --serve --port ${WG_PORT} ${SERVER_PUB_KEY} first.available.ip.address

# on the client:
sudo su -c "curl -Ls https://raw.githubusercontent.com/greyltc-org/wg-request/master/join-wg.sh | bash /dev/stdin ${SERVER_ADDRESS} [${WG_INTERFACE}]"

Server

Imagine you're person A, and you're running a wireguard peer that you'd like to act as a traditional VPN server. You know your public key for that peer is RNveEHSE4Ky+4X0aybFz5W42NAIvTv+GB4iSv3UAZAM=. Also imagine you have an address space available for new client peers to join your network that begins at 10.32.3.4. If your peer listens on port 51820, you should run:

$ ./wg-request --serve --port 51820 RNveEHSE4Ky+4X0aybFz5W42NAIvTv+GB4iSv3UAZAM= 10.32.3.4
Wireguard request server started listening on port 43454

Client

Now imagine you're person B, and you'd like to request to join your wireguard peer to the network that person A is running. You know your public key is Wpu83JMdnaJVGsrZeOJ4PZbdajRXzE0KVhLcvGEXLBg= and you also know that person A's server is running at wireguardvpnserver.motorcycles. You should run:

$ ./wg-request Wpu83JMdnaJVGsrZeOJ4PZbdajRXzE0KVhLcvGEXLBg= wireguardvpnserver.motorcycles
[Interface]
Address = 10.32.3.4/24

[Peer]
PublicKey = RNveEHSE4Ky+4X0aybFz5W42NAIvTv+GB4iSv3UAZAM=
Endpoint = wireguardvpnserver.motorcycles:15820

🎉 Look what you got back! A configuration snippet you can use to configure your peer to join person A's network! Let's hope they let you in!

Server

Now imagine you're person A again. You look at your terminal and see someone has requested to join your network:

$ ./wg-request --serve RNveEHSE4Ky+4X0aybFz5W42NAIvTv+GB4iSv3UAZAM= 10.32.3.4
Wireguard request server started listening on port 43454

Maybe you see enough info there to decide if you want to configure your peer to let them join. You even got a little snippet to make it easier to add them if you'd like!
