TLS/SSL Handshake
Definition
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The TLS handshake negotiates encryption algorithms, authenticates the server via certificates, and establishes cryptographic keys.
Explain Like I'm New
Before talking securely, the browser and server meet in secret to verify ID cards (certificates) and agree on a secret code language (symmetric keys) that only they understand.
