Tor Hidden Service Buildpack for Heroku

This buildpack sets up a Tor hidden service for your app on Heroku.

Setup

Create a Heroku app as normal, with any buildpacks you typically use.

Then:

$ heroku buildpacks:add https://github.com/hernanex3/heroku-buildpack-tor.git

With the buildpack installed, you'll need to modify your Procfile such that the hidden service will be setup when the app runs.

web: ./tor/bin/run_tor <cmd you'd normally run>

While web works just fine, so too will any other process type. Use web if you want the app to be accessible generally, as well as over Tor. Use <any other type> (e.g. foo), to avoid Heroku's router routing to your app like so:

foo: PORT=9999 ./tor/bin/run_tor <cmd you'd normally run>

Your app will only be accessible over Tor, through your configured .onion address.

Variables

Of course, Tor hidden services require that you provide a private_key and it's SHA, for the .onion name. You'll need to provide these as env vars:

  • HIDDEN_PRIVATE_KEY: The contents of a private_key file
  • HIDDEN_DOT_ONION: The onion name for the private_key.

Features

  • Verifies integrity (see yourself how its done, I'm not sure its correct)
  • Caches compilation
You can’t perform that action at this time.
