Certifi: Ruby SSL Certificates

This installable Rubygem contains a CA Bundle that you can reference in your Ruby code. This is useful for verifying HTTP requests, for example.

This is CA Bundle is derived from Mozilla Firefox's canonical set.

Installation

Add this line to your application's Gemfile:

gem 'certifi'

And then execute:

$ bundle

Or install it yourself as:

$ gem install certifi

Usage

To reference the installed CA Bundle, you can use the built-in function:

> require 'certifi'
> Certifi.where
=> #<Pathname:/home/hone/.gems/ruby/2.1.0/ruby-certifi-14.5.14/lib/certifi/vendor/cacert.pem>

You can use this with net/http to verify the SSL certificate:

require 'uri'
require 'net/https'
require 'certifi'

uri  = URI.parse('https://httpbin.org/')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl     = true
http.verify_mode = OpenSSL::SSL::VERIFY_PEER
http.ca_file     = Certifi.where
http.start do
  http.request_get(uri.path) do |res|
    puts res.body
  end
end

Enjoy!
