🔐 Create Your Own SSL Certificate Authority (Root + Intermediate + Domain) with OpenSSL | Bash Automation

In this video, we’ll walk through creating your own certificate authority( Certificate Authority (CA) using Step CA) on Linux so that you can run HTTPS sites locally without issue.
I will explain how to generate valid self-signed SSL certificates for your internal network. We will use an open-source tool, OpenSSL to create an SSL cert for my Proxmox Server, that is valid for my internal domain and my private IP address

You’ll learn how to generate:
✅ Root CA
✅ Intermediate CA
✅ Domain SSL Certificate (with SAN & Wildcard)
✅ Proper SSL Certificate Chain (chain.pem)
✅ Verify certificates like a pro

This is perfect for Homelab, Intranet, Dev/Test servers, Docker, Kubernetes, Nginx, Apache, Traefik, Proxmox Server and any internal infrastructure where you want full control over SSL certificates without relying on third-party CAs. Perfect for Homelab, Dev/Test, Docker, Kubernetes, Nginx, Apache, Proxmox Server & Traefik. You’ll also learn how to build a proper SSL chain, add SAN & wildcard domains, and trust your CA on Windows, Linux, macOS, Android, iOS & Docker.
