This article demonstrates how to implement Full (Strict) SSL/TLS encryption by combining Cloudflare's managed frontend certificates with Let's Encrypt wildcard certificates on your origin server.

This guide demonstrates how to set up secure TLS 1.3 communication using Ed25519 elliptic curve certificates and a private Certificate Authority (CA). It covers encrypted client-server communication with modern, efficient cryptographic standards — ideal for internal systems, microservices, and zero-trust network architectures.
