ssl_expiry

Overview

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

Installation

Add this line to your application's Gemfile:

gem 'ssl_expiry'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ssl_expiry

Usage

Simple Usage

require 'ssl_expiry'

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

Results:
{"wolfsoftware.com"=>{"status"=>200, "expires_on"=>"02 Aug 2024", "expires_in"=>57, "common_name"=>"wolfsoftware.com", "issuer"=>"Let's Encrypt"}}

Multiple Domains

It is possible to check a list of domains rather than just single domains, this is done by passing a list[] to SSLExpiry::SSLExpiry.check_certificates.

require 'ssl_expiry'

SSLExpiry::SSLExpiry.check_certificates(['wolfsoftware.com', 'wolfsoftware.net'])

Displaying the output

require 'ssl_expiry'

results = SSLExpiry::SSLExpiry.check_certificates('wolfsoftware.com')
SSLExpiry::SSLExpiry.display_results(results)

This would give the following output

----------------------------------------------------------------------------------------------------
 Domain                         | Status
----------------------------------------------------------------------------------------------------
 wolfsoftware.com               | expires on 02 Aug 2024 (in 57 days) [CN=wolfsoftware.com]
----------------------------------------------------------------------------------------------------

check-ssl -d wolfsoftware.com,wolfsoftware.net

------------------------------------------------------------------------------------------------------------------------

Custom port

If you want to check an SSL expiry on a custom port you can do this by adding the port to the end of the domain.

  check-ssl -d wolfsoftware.com:8080
