This library generally provides helper methods which makes working with OpenSSL a little more bearable. It does, however, provide some additional structures (such as a CertificateChain) which extend the traditional features of the library.
With Bundler:
gem 'openssl-extensions', :require => 'openssl-extensions/all'
With standard RubyGems:
gem install openssl-extensions
require 'rubygems'
require 'openssl-extensions/all'
Once required, the extensions are automatically applied.
In general, this extension library should be somewhat transparent to you. It does not directly provide many classes with which you might interact. Instead, it extends the current classes provided by Ruby's OpenSSL library (being OpenSSL::X509::Request, OpenSSL::X509::Certificate, and OpenSSL::X509::NAME).
Below is a simple example exercising a few helpers provided by this library:
csr_body = File.read('example.csr') # assuming this is valid and exists
request = OpenSSL::X509::Request.new(csr_body)
request.subject.common_name # => "example.com"
request.subject.organization # => "Example Corp"
request.subject.locality # => "Orlando"
request.subject.region # => "Florida"
request.subject.country # => "US"
request.subject.location # => "Orlando, Florida, US"
request.strength # => 2048
request.challenge_password? # => false
request.subject_alternative_names # => ['example.com', 'www.example.com']
