(operating system)


(Secure SHell) A security protocol for logging into a remote server. SSH provides an encrypted session for transferring files and executing server programs. Also serving as a secure client/server connection for applications such as database access and email, SSH supports a variety of authentication methods. See headless system.

SSH was developed in the mid-1990s by Helsinki University researcher Tatu Ylönen as a secure alternative to non-secure telnet, rlogin and rsh programs for Unix servers. SSH-2, a more advanced version introduced in 1998, was standardized by the IETF and is not compatible with SSH-1.

Secure File Transfer: SCP and SFTP
Secure Copy Protocol (SCP) is a version of the Unix remote copy (rcp) command that is widely supported on Unix systems running SSH-1. The SSH File Transfer Program (SFTP) was developed by the IETF for transferring files with SSH-2.

All Platforms - Free and Paid
SSH is widely used on all platforms, and software is available as open source from the OpenSSH group ( and numerous commercial vendors, including SSH Communications Security Corporation (, the company founded by Ylönen. See FTPS.
