OpenSSH is a free and open-source suite of secure networking utilities that has become a critical tool for system administrators and developers who need to securely manage and access remote systems over unsecured networks. In this article, we will take a closer look at what OpenSSH is, how it works, and its importance in modern computing.
OpenSSH History
OpenSSH was developed in 1999 as an open-source implementation of the Secure Shell (SSH) protocol. The SSH protocol was developed as a replacement for the older Telnet protocol, which transmitted login credentials and other sensitive data in clear text over the network, making them vulnerable to interception and unauthorized access.
