The latest version of the Transport Layer Security protocol (RFC 8446), released in 2018. TLS 1.3 reduces the handshake to one round trip (1-RTT) and supports an optional 0-RTT mode for resumed sessions, cutting latency significantly. It removes insecure algorithms — RSA key exchange, RC4, 3DES, MD5, SHA-1, and CBC-mode ciphers — and mandates forward secrecy for all cipher suites via ECDHE key exchange. TLS 1.3 is required for HTTP/3 over QUIC.
