TLS Handshake

← Back to TLS and SSL

The process of establishing a secure TLS connection: Client Hello (supported cipher suites), Server Hello (chosen cipher suite + certificate), key exchange, and verification. TLS 1.3 reduces this to a single round trip (1-RTT), with optional 0-RTT resumption.

Key Properties

• Client Hello and Server Hello
• Certificate Exchange
• Key Exchange Negotiation
