Keeping knowledge of your certificate status is very important and OpenSSL does a good job here. Also, if you do not want to engage (or mess up) with the command line, you can usedowntime monitoring serviceslike Better Uptime to automatically check the certificates. Uptime (formerly Better Up...

Linux users can easily check an SSL certificate from the Linux command-line, using theopensslutility, that can connect to a remote website overHTTPS, decode an SSL certificate and retrieve the all required data. Cool Tip:If your SSL certificate expires soon – you will need to generate a ne...

This module allows one to (re)generate OpenSSL certificates. It implements a notion of provider (ie. selfsigned, ownca, acme, assertonly, entrust) for your certificate. The assertonly provider is intended for use cases where one is only interested in checking properties of a supplied certificat...
Check if the file has sufficient read permissions for the OpenSSL command user. ls -l certificate.pem If the permissions are too restrictive, change them to allow read access: chmod 644 certificate.pem This command makes the file readable by the owner and other users, allowing OpenSSL to acces...
OpenSSL is an open-source command line tool that is commonly used to generate private keys, create CSRs, install your SSL/TLS certificate, and identify certificate information.
that follows from allowing a certificate for a public-facing website to expire. There are plenty of monitoring tools to keep an eye on this and ensure that it doesn’t happen to you, but what if you just want to quickly check a certificate’s expiration date from the command line?
