Secure Shell (SSH) refers to an application, or its protocol, that lets you log in to another computer over a network, run commands on a remote system, and copy files to another system. It was designed to replace older tools such as rsh, rlogin, and Telnet, and provides strong authentication and the ability to communicate securely over insecure networks. It uses port 22 by default. Because SSH uses encryption, even if the communication is exposed, it appears only as unintelligible encrypted characters.
