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.
