The SSH protocol provides the following services:
The generated private key, the encryption generator, and the shared prime number are used to generate a public key that is derived from the private key, but which can be shared with the other party.
At the beginning of the connection, the client checks whether the host that is contacted is registered to the client or not.
The client sends the authentication process to the server using the 128 bit enkrisp technique.
Authenticating the User's Access to the Server
The server sends the client this encrypted message.
The client then sends this MD5 hash back to the server as an answer to the encrypted number message.
