Inspect SSL Certificates with OpenSSL 🔍

Throughout this series we've used the "-text" command to extract everything inside a Certificate, CSR, or Private Key file. But in some cases it's more beneficial to extract only the specific piece of information you need from a Certificate.

That is what we will be focusing on in this video. We will use the openssl req and openssl x509 utilities to extract individual pieces of information from a Certificate and CSR.

This lesson is a preview lesson from my OpenSSL Training Course:
