hyper-auth-proxy

A proxy to do http basic auth from a JWT token and redis session credentials

usage

Little auth proxy based on hyper-reverse-proxy that can be used to add Basic auth header for a backend service without having to send credentials base64 encoded on the web.

It will use JWK token key sid field to seek for the credentials in a Redis instance. The JWT token is read from Authorization cookie. The credentials are stored in json :

json { "credentials": "dXNlcjp0ZXN0" }

They can be used "as is" or the credentials can be encoded (for example with AES).

Without encoded credentials, the proxy will make a request with Authorization header : bash Authorization: Basic dXNlcjp0ZXN0 The main should contain a tokio main section and call the run_service function.

Example : ```rust,norun use hyperauthproxy::{runservice, ProxyConfig};

#[tokio::main] async fn main() { let (tx, rx) = tokio::sync::oneshot::channel::<()>(); let config = ProxyConfig::default(); let server = runservice(config.clone(), rx).await; println!("Running auth proxy on {:?} with backend {:?}", config.address, config.back_uri); if let Err(e) = server.await { eprintln!("server error: {}", e); } }

```

The proxy configuration contains the following parameters : rust,no_run use std::net::SocketAddr; struct ProxyConfig { pub jwt_key: String, pub credentials_key: String, pub back_uri: String, pub redis_uri: String, pub address: SocketAddr, }

logging && debugging

It uses log API so for example with env_logger it can be launched with

shell $ RUST_LOG=debug hyper-auth-proxy

And you should have logs like :

shell [2022-03-16T12:51:26Z INFO my_auth_proxy] Running auth proxy on 127.0.0.1:3000 with backend "http://backend" [2022-03-16T12:51:33Z DEBUG hyper_auth_proxy] cannot find auth cookie: no cookies header [2022-03-16T12:53:21Z DEBUG hyper_auth_proxy] cannot find auth cookie: no auth cookie [2022-03-16T12:53:35Z DEBUG hyper_auth_proxy] cannot decode jwt token: cannot decode jwt token (No claims component found in token string)
