Key exchange session key
Web4 nov. 2024 · In an RSA key exchange, public key encryption facilitates the exchange of a pre-master secret and a randomly generate number from the client that, together, generate a shared session key. With the Diffie-Hellman key exchange, the server and client instead mutually agree upon a value that’s used for the session key. (More on that shortly.) Web23 mrt. 2024 · The main purpose of the Diffie-Hellman key exchange is to securely develop shared secrets that can be used to derive keys. These keys can then be used with symmetric-key algorithms to transmit information in a protected manner.
