DuoApi

A thin, zero depedency library for connecting to the Duo Auth API.

Installation

Add this line to your application's Gemfile:

gem 'duo-api'

And then execute:

$ bundle

Or install it yourself as:

$ gem install duo-api

If you're for some reason using REE or 1.8.7, you must also install the json Gem.

Configuration

During app initialization:

require 'duo-api'
DuoApi.config do |config|
  # Found on Duo Admin panel for the application you've set up
  config.hostname = "api-xxxxx.duosecurity.com"
  config.integration_key = "asdf"
  config.secret_key = "asdf"

  # ONLY for Duo Web
  # Generate a somewhat long secret token (40+ characters).
  # If you're using Rails, `Rails.application.secret_token` should suffice
  # can also run `duo-api app_secret`
  config.app_secret = "Long app secret"
end

For Rails this would go in something like config/initializers/duo.rb. Keep in mind, you likely don't want to store these keys in your repository.

Configuration Caveat

Upon completion of the general features we noticed that Duo needs separate credentials for different APIs. This config is currently Global. We (or someone) should be adding a way to switch between credentials or perhaps it would be best to initialize a Client class for each credential set

Usage

response = DuoApi.get("/auth/v2/check")
response.success? # => true
response.body["response"]["time"] # => 1357020061

response = DuoApi.post("/auth/v2/preauth", :params => { :username => "jphenow" })
response.success? # => true
response.code # => "200"
response.body["response"]["result"] # => "auth"
response.message # => "Account is active"

response = DuoApi.post("/auth/v2/preauth")
response.success? # => false
response.code # => "400"
response.message # => "Missing required request parameters"

See the Duo API documentation for a full list of available endpoints.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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.
