NAME

       secsh - the Secure Shell protocol

DESCRIPTION

       secsh  is  a  protocol suite for secure remote login and other secure network services over an insecure network. It is outlined in [SECSH].
       It has three major components:

       The Transport layer protocol
	      This protocol, specified in [SECSH-TLP], provides  server  authentication,  confidentiality,  and  integrity  with  perfect  forward
	      secrecy.

       The User authentication protocol
	      This protocol, specified in [SECSH-AUTH], is used to authenticate a client to a server.

       The Connection protocol
	      This protocol, specified in [SECSH-CONN], multiplexes an encrypted tunnel into several logical channels.

IMPLEMENTATIONS

       Several implementations of the secsh protocol suite exist.

       The SSH2 product of SSH Communications Security Ltd., Finland <URL:http://www.ssh.fi> was the first. The secsh protocol suite has benefited
       a lot from their experience with their older SSH1 product, which is still in widespread use; it implements an older protocol ([SSH1]).

       The lsh suite of programs is a free implementation of the secsh protocol suite; it is distributed under the GNU General Public License.
