  "description": "HTTPS (HTTP over TLS) provides three essential security properties: **confidentiality** (encryption prevents eavesdropping), **integrity** (tamper detection), and **authentication** (server identity verified via X.509 certificates). TLS 1.3 (RFC 8446, 2018) is the current standard — it reduced the handshake from 2 to 1 round trip (0-RTT on resumption), removed all obsolete algorithms (RSA key exchange, CBC-mode ciphers, SHA-1, MD5), and mandates forward secrecy (all key exchanges use ECDHE). As of 2026, over 90% of pages loaded in Chrome use HTTPS (Google Transparency Report), and Let's Encrypt has issued more than 400 million free certificates.",
