[[Secure Shell]] ([[SSH]]) is a network protocol for secure data communication, remote shell services or command execution, and other secure network services between two [[computers]] connected through a secure channel, even over an insecure network: server and client (each running [[SSH]] [[server]] and [[SSH]] client programs). The protocol specification distinguishes two main versions called SSH-1 and SSH-2.

The most well-known application of [[protocol]] is for access to shell accounts on [[Unix]] [[operating systems]]. It was designed as a replacement for Telnet and other secure shell protocols like Berkeley's rsh and rexec protocols, which send information, especially passwords, in plaintext, making them vulnerable to interception and disclosure using packet analysis. The encryption used by [[SSH]] is intended to provide confidentiality and integrity of data across insecure networks, such as the [[Internet]].
