This interactive demonstration visualizes the SSL/TLS handshake process used to establish secure connections. Watch as client and server exchange messages, negotiate cipher suites, and establish encrypted communication channels.
What you'll learn:
The SSL/TLS handshake is a process where the client and server establish a secure connection by:
Forward Secrecy: Even if the server's private key is compromised, past sessions remain secure.
