[edit intro]

The Secure Shell or SSH is a network protocol for secure remote login, providing an encrypted connection instead of the unencrypted, and therefore insecure, connection of telnet.

There was an IETF Working Group for SSH; it has completed its work. The protocol is documented in a series of RFCs. [1] [2] [3] [4] [5] [6] [7] [8]

Most Unix-based systems include an SSH client, and often a server as well. The Open SSH project, part of OpenBSD, are the main developers. A client for Windows is Putty.
