It has some useful methods to handle ssl certificate.
Add this line to your application's Gemfile:

And then execute:
$ bundle
Or install it yourself as:
$ gem install ssl_certificate
require 'ssl_certificate'
# create object from certificate of pem or der format
cert_pem = File.read("spec/test_data/www.example.com.crt")
cert = SslCertificate::Certificate.new(cert_pem)
cert.common_name
# => "www.example.com"
cert.alternative_names
# => ["example.com", "hoge.example.com"]
key_pem = File.read("spec/test_data/www.example.com.key")
cert.check_private_key_str(key_pem)
# => true
# check whether a fqdn corresponds to the certificate
cert.check_fqdn("www.example.com")
# => true
cert.check_fqdn("hoge.example.com")
# => true
