That SSL Checker

A simple tool to check SSL certificate expiry and details for any hostname.

That SSL Checker is a hosted utility that allows users to quickly inspect the SSL/TLS certificate of a given server.

What is it?

This is a simple tool that checks the SSL Certificates for hosts and stores it locally. The main advantage is to have this tool available everywhere, even on mobile.

How to use?

The usage is simple, just input the address:port like dcpri.me:443 or example.com:443 and press Enter/Return.

Once added the information will be shown as a card. To remove any existing card just click on the × icon shown at the top right of it.

How it works?

All the details are coming from API call, /check. It takes at max two parameters, addr_strings and force.

  • addr_strings: it can be an array of host:port strings.
  • force: is a boolean that tells the API to ignore cache and re-check.

Where can I find more details?

The name of the project is that-ssl-checker, code available here.

Note: To have a quick response the API underneath is caching the certificates for at max an hour. In case if you want to check the latest click on Force Check button.
