proxifier-rs

Simple proxy client library to relay network packets towards a destination target using a proxy. With built-in support for TLS.

• Supports SOCKS4/5 and HTTP/HTTPS type proxies

This is a Rust port of proxifier. Specifically designed for production use with ProxyBeast software.

Uses Async

• With tokio
• Tracing support todo

Supports

• TLS via rustls

If you want to use a different TLS library, feel free to disable this crate's default Cargo feature: tls

Summary of the API

Exports simple connect functions from which a [TcpStream] is obtained and can in turn be wrapped into a [TlsStream<TcpStream>] with support for TLS.

Quick glance into the API

#[tokio::test]
async fn test_socks5_ipv4() -> std::result::Result<(), Box<dyn std::error::Error>> {
    let mut conn = crate::socks5::connect(
        Context {
            proxy: "194.113.119.68:6742".parse()?,
            destination: NetworkTarget::IP("104.26.12.205:80".parse()?),
        },
        Auth::UserPass("vcilvnba".into(), "vi14viqvvrr7".into()), // or Auth::NoAuth
    )
    .await?;

    conn.write(b"GET / HTTP/1.1\r\nHost: api.ipify.org:80\r\nConnection: close\r\n\r\n")
        .await?;

    let mut resp = String::new();
    conn.read_to_string(&mut resp).await?;
    println!("out: {:?}", resp);
    Ok(())
}
