Protect your key server with Keyless SSL and Cloudflare Tunnel integration

What this post added

Introduced integration of Cloudflare Tunnels with Keyless SSL to secure key server communication. Previously, Keyless SSL required a public DNS record for key servers, exposing them to the internet. The new approach uses Cloudflare Tunnels to create a private, secure channel, meaning the key server's IP address is no longer publicly discoverable. This enhances security by ensuring only Cloudflare initiates connections to the key server, reducing its attack surface.
