TLS/SSL Handshake

Category: science

The process by which a client and server establish an encrypted connection channel.

The handshake initializes the secure transit tunnel. The client and server exchange cryptographic capabilities, validate the server's digital certificate via the PKI, and securely generate symmetric session keys to encrypt all subsequent application data payloads.

Common Examples

• Our API performance optimization project focused on reducing the latency overhead of the initial TLS handshake sequence.
• A failed TLS handshake usually indicates either an expired root certificate or an unsupported cryptographic cipher mix on the server side.
