This is the portable version of OpenSSH, a free implementation of the Secure Shell protocol as specified by the IETF secsh working group.
Ssh (Secure Shell) is a program for logging into a remote machine and for executing commands on a remote machine. It provides secure encrypted communications between two untrusted hosts over an insecure network. X11 connections and arbitrary TCP/IP ports can also be forwarded over the secure channel. It can be used to provide applications with a secure communication channel.
This package provides the sshd server.
In some countries it may be illegal to use any encryption at all without a special permit.
sshd replaces the insecure rshd program, which is obsolete for most purposes.
