TLS handshake - Symmetric scheme

From what I can tell TLS works using both symmetric and assymmetric encryption. The assymmetric schemes are used to exchange keys but when and what symmetric schemes are used?

Solution

  • The asymmetric schemes are used to exchange keys

    and digital-signatures.

    The symmetric schemes are used to data transfer with the agreed symnetric key during the key-exchange.

    This is called Hybrid cryptosystem.
