His SSH client opens a connection to the server on port 22 where the SSH daemon listens. First, the ciphers that will be used are agreed upon, then a session key to encrypt the connection is established using Diffie-Hellman Key exchange, but we won't go into the details on that here.

WebFeb 27, 2024 · The idea of ephemeral Diffie Hellman is that you create two new key pairs for each connection. Then you can throw away the key pair (s) after the connection has been set up and authenticated. Even if the private key is factored or otherwise retrieved then you could only attack a single connection.
