TLS 1.3
The current, streamlined version of the TLS encryption protocol.
TLS 1.3 modernised secure connections: a faster handshake, only strong cipher choices, and forward secrecy by default. Central to it is the key schedule, a defined sequence of steps that derives the encryption keys from the handshake. Implementing that key schedule correctly is what makes a TLS 1.3 stack interoperable and secure.
