State TLS handshake basics precisely and explain why it matters in 2-3 sentences.

## TLS Handshake Basics 1. **Client Hello**: Client sends supported cipher suites and TLS version 2. **Server Hello**: Server selects cipher suite and sends its certificate 3. **Key Exchange**: Both parties generate shared session keys using public-key cryptography 4. **Finished**: Both confirm encryption is working with encrypted verification messages ## Why It Matters The TLS handshake establishes an encrypted channel before any sensitive data is transmitted, protecting against eavesdropping and man-in-the-middle attacks. It authenticates the server's identity through digital certificates, ensuring you're actually communicating with your intended recipient (like your bank, not an imposter). Without this process, all internet communication—passwords, credit cards, private messages—would be transmitted in plain text, readable by anyone monitoring network traffic.
