OpenSSH

Secure Shell(SSH) supports encrypted connections over networks and prevents the user ID and password from being transmitted in clear text.

Using Secure Shell, a secure and authenticated connection can be established between two stations over the Internet or other non-secure networks.

OpenSSH is a free implementation of Secure Shell (SSH) developed by the OpenBSD Project. OpenSSH has a graphical user interface and is supported by several operating systems, including Unix and Windows. In terms of deployment, OpenSSH can be mentioned with WinSCP, PuTTY and OpenVPN.
