Unlocking The Secrets Of TLS
summary
Browsers and servers use asymmetric RSA to bootstrap a high‑speed AES session key but that creates a single master decryption key risk — Snowden (2013) and Heartbleed (2014) show how private keys get exposed. The practical fix is the Diffie‑Hellman key exchange (DHE/ ECDHE since 2008) which delivers forward secrecy so stolen server keys don’t decrypt recorded sessions. Chrome is now trialing post‑quantum primitives; goal is ~30‑year resistance against future quantum attacks.
