The Foundation of HTTPS: Mastering TLS 1.3 and Certificate Management

With over 95% of web traffic now encrypted via HTTPS and TLS 1.3 accounting for 60% of encrypted connections, understanding certificate architecture and management is no longer optional for developers and sysadmins. TLS 1.3's one-round-trip handshake significantly reduces latency while improving security by eliminating legacy algorithms, making it essential for modern web performance. Proper certificate lifecycle management — from issuance through revocation — directly impacts both security and user experience.
