# wireproxy
A wireguard client that exposes itself as a socks5 proxy or tunnels.

# What is this
`wireproxy` is a completely userspace application that connects to a wireguard peer,
and exposes a socks5 proxy or tunnels on the machine. This can be useful if you need
to connect to certain sites via a wireguard peer, but can't be bothered to setup a new network
interface for whatever reasons.

# Why you might want this
- You simply want to use wireguard as a way to proxy some traffic.
- You don't want root permission just to change wireguard settings.

Currently, I'm running wireproxy connected to a wireguard server in another country,
and configured my browser to use wireproxy for certain sites. It's pretty useful since
wireproxy is completely isolated from my network interfaces, and I don't need root to configure
anything.

# Usage
```
./wireproxy [path to config]
```
