OpenSSH (also known as OpenBSD Secure Shell[a]) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture.[4][5]
OpenSSH started as a fork of the free SSH program developed by Tatu Ylönen; later versions of Ylönen's SSH were proprietary software offered by SSH Communications Security.[6] OpenSSH was first released in 1999 and is currently developed as part of the OpenBSD operating system.
OpenSSH is not a single computer program, but rather a suite of programs that serve as alternatives to unencrypted protocols like Telnet and FTP. OpenSSH is integrated into several operating systems, namely Microsoft Windows, macOS and most Linux operating systems,[7][8] while the portable version is available as a package in other systems.[9][10][11]
