, the Internet communication was plain text communication. Once intercepted, the content was exposed. In 1995, Finnish scholar Tatu Ylonen designed the SSH protocol to encrypt all login information, which became a basic solution for Internet security and was quickly promoted worldwide, it has become a standard configuration for Linux systems.
It should be noted that SSH is only a protocol and there are mul

OpenSSH
OpenSSH is a free open-source implementation of the SSH (Secure Shell) protocol. It uses secure and encrypted network connection tools instead of Telnet, FTP, rlogin, RSH, and rcp tools. OpenSSH supports SSH protocol versions 1.3, 1.5, and 2. Since OpenSSH 2.9, the default protocol is version 2, which uses the RSA key by default.
