Basically, with RSA, the server sends its public key, the client generates a random secret, encrypts it with the public key and sends it back to the server. The server then decrypts it with its private key.

WebFeb 8, 2024 · Forward secrecy is a property that says, basically, that once the exchange is over, the involved parties do not keep around all the secret information that allows decryption: the data has been encrypted on the sender side, and decrypted by the recipient, and nobody (except the attacker, of course!) needs to decrypt it again, so the encryption …
