Why HTTPS Beats HTTP: Encryption, Certificates, and TLS Handshake Explained

This article explains why HTTP is insecure—prone to eavesdropping, tampering, and identity spoofing—and how HTTPS uses symmetric and asymmetric encryption, hash functions, digital certificates, and a four‑step SSL/TLS handshake to provide confidentiality, integrity, and authentication for web traffic.
