AcmeChallenge

Simple rack middeware for responding to ACME challenge like LetsEncrypt uses.

Add this line to your application's Gemfile:

gem 'acme_challenge'

And then execute:

$ bundle

Or install it yourself as:

$ gem install acme_challenge

Simply mount as middleware and specify the challenge response. Add something like this to your config.ru:

use AcmeChallenge, 'UG0AjhvK-plt_4TjdxFMHgINYdqB_At1ukwMH1ItZXo.pI79XvTWAEyw1GO5BJYjxGs5KZrrSDSum9i5JZqeYsQ'

It may be handy to do something like this:

use AcmeChallenge, ENV['ACME_CHALLENGE'] if ENV['ACME_CHALLENGE']

Using environment variables is nice since you don't have to redeploy to do a new challenge.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
