LetsEncryptPlugin

Rails engine for generating Let's Encrypt certificates

Installation

Add this line to your application's Gemfile:

gem 'lets_encrypt_plugin', git: "https://github.com/Ragnarson/lets_encrypt_plugin.git"

And then execute:

$ bundle

Configuration

Initializer

Create an initializer in config/initializers with

LetsEncryptPlugin.configure do |config|
  config.domains = %w(example.com www.example.com)
  config.email_contact  = "whois@example.com"
  config.private_key = "KEY CONTENT" # File.read("server.key")

  # config.endpoint = "https://acme-v01.api.letsencrypt.org"
end

All domains have to point to your application otherwise validation will fail and certificate won't be generated.

Email and private key are used for Let's Encrypt registration. To generate private key you may use

openssl genrsa -out server.key 4096

Endpoint will be set based on Rails.env to either https://acme-v01.api.letsencrypt.org for production or https://acme-staging.api.letsencrypt.org for any other environment.

Database migrations

Challenges will be stored in database for validation purposes.

Copy migrations to your application and run them:

rake lets_encrypt_plugin:install:migrations

rake db:migrate

Mounting engine

Mount LetsEncryptPlugin at the top of routes.rb:

  mount LetsEncryptPlugin::Engine, at: '/'

Usage

TODO

• Generator for initializer
• Different output
• Release on rubygems.org
