This is a simple little gem for checking when an SSL will expire.

Installation

Add this line to your application's Gemfile:

And then execute:

Usage

Simple Usage

  require 'ssl_expiry'

  SSLExpiry::SSLExpiry.check_certificates('antiphoton.com')

  Results:
  {"antiphoton.com"=>{"status"=>200, "expires_on"=>"09 Mar 2019", "expires_in"=>16, "common_name"=>"antiphoton.com", "issuer"=>"COMODO CA Limited"}}

Displaying the output
