Technical Summary
 SSH is a protocol for providing an authenticated, integrity protected
 and encrypted stream between two end-points. It can optionally
 provide compression as well as multiplexing several virtual streams
 within a single TCP connection. This multiplexing feature is
 particularly useful for "tunneling" other protocols such as the X
 Window System.

 A Main focus of the SSH protocol is to provide a transport for remote
 login from a client computer system to a server system.
