Tor Hidden Service Buildpack for Heroku

UPDATED Tor v 0.4.6.7

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

Tor Version 3 urls

Setup

1. Create a Heroku app as normal, with any buildpacks you typically use.
2. Create the directory -> 'hidden_service' in the root of your build repo.
3. Then:

$ heroku buildpacks:add https://github.com/quantumalchemy/heroku-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.

Maintain your own persistent v3 url

Setup:

Tor hidden services require that you provide the hs_ed25519_secret_key v3 for the .onion url (hostname).

1. Copy ONLY the: hs_ed25519_secret_key file from '/app/hidden_service/' in the running dyno after first deployment to -> 'hidden_service' that you just created in your -> git build repo

2. You'll need to provide env vars:

• HIDDEN_DOT_ONION: from the hostname file under the running dyno 'hidden_service'

3. After commited changes - re deploy .. and Enjoy!

Features
