Reading an existing config

[house-of-vanity]

Hi, could you implement reading an existing config rather than rewriting it? I know that you cannot obtain servers pub and clients secrets from it. Anyway it will be convenient to migrate seamlessly to this tool. I moved my config with simple Python script.

import wgconfig # default iniparser cannot read WG configs.
import json

cfg_path = "/etc/wireguard/wg0.conf"
server_public_key = "IfhwVCps7GEtplKh44wGEHhj892leqpnDXeAKkAmAWg="
public_ip = "10.10.10.1"
dns = "8.8.8.8"

wg = wgconfig.WGConfig(cfg_path)
wg.read_file()

cfg = dict()

_id = 1
peers = list()
for pk, data in wg.peers.items():
    p = dict()
    p["Active"] = False
    p["ID"] = _id
    p["Name"] = data["PublicKey"][0:7]
    p["PrivateKey"] = None
    p["PublicKey"] = data["PublicKey"]
    p["VirtualIP"] = data["AllowedIPs"].split("/")[0]
    p["KeepAlive"] = 0
    peers.append(p)
    _id += 1


cfg["PublicIP"] = public_ip
cfg["PublicKey"] = server_public_key
cfg["DNS"] = dns
cfg["WgConfigPath"] = cfg_path
cfg["Port"] = str(wg.interface["ListenPort"])
cfg["VirtualIP"] = wg.interface["Address"].split("/")[0]
cfg["CIDR"] = wg.interface["Address"].split("/")[1]
cfg["PrivateKey"] = wg.interface["PrivateKey"]
cfg["Active"] = True
cfg["Peers"] = peers

print(json.dumps(cfg, indent=4))

Hey there. That's a good idea. I originally implemented it to always overwrite because without a proper config file (with secrets, etc.) it basically doesn't work. I could make it a command-line option when starting the app. I think that might be the best way to do it. What do you think?

Also I've basically slowed down progress on this as I'm currently in the process of rewriting it in Rust.

Sounds good.
Also I'd like to use Rust version too because I have some experience with Rust. Do you have any code already?
