Ninja proxy

Generate temporary URLs with a stateless service

This project grew out of the need to share authenticated proxies with third-party services, so that they can all operate with the same IP. Several proxy-providers provide mechanisms for this, but they usually require sending your username and password to the third-party and this can be very risky. Ideally you want some temporary URL that opaquely routes the traffic from the third-party to your proxy provider, and that is exactly what this project provides.

Quick start

Clone this repo and build the project. Assuming that golang is installed, you build the server using

make binary

that will put it into ./bin/ninja-proxy.

You can install the helper utilities by running

source activate.sh

and load a key into your terminal with

KEY=$(ninja-key)

Now you can run the service (in the background) using

bin/ninja-proxy -key $KEY &

which by default will run on 0.0.0.0:7777.

To generate a link for the service call

link=$(ninja-link 120 $KEY http://username:[email protected]:80 --headers test-header=foo another=bar)

$ curl $link/headers
{
  "headers": {
    "Accept": "*/*",
    "Another": "bar",
    "Authorization": "Basic dXNlcm5hbWU6cGFzc3dvcmQ=",
    "Host": "httpbin.org",
    "Test-Header": "foo",
    "User-Agent": "curl/7.72.0",
    "X-Amzn-Trace-Id": "Root=1-5f56788f-d9513fb01690f9080adeb528"
  }
}

Notice how the username and password are automatically added to the Authorization header, you can do the same thing with a proxy URL and it will just work.

The generated link contains a username and header field with all of this information encrypted so that it can't be read. It looks quite messy, but it works.

Proxies

There's not very much else to say, use exactly the same procedure as above to wrap your proxy URL and use it as normal

proxy_link=$(ninja-link 120 $KEY "http://$PROXY_USER:$PROXY_PASS@$PROXY_HOST:$PROXY_PORT")
curl -x $proxy_link -k http://httpbin.org/ip

Docker image

A dockerfile has been included with this repository and can be built using make docker. Then you can run this using

NINJA_PORT=7777
docker run --rm -d -p $NINJA_PORT:7777 ninja-proxy

Limitations

This is a young project created for a specific problem at hand. You can use this to proxy both HTTP and HTTPS connections, but right now it only supports HTTP proxies or URLs using HTTP/1.x.
