How To Set Up an SSH Key For Secure Connections

The Secure Shell Protocol (SSH) is perhaps the most well-known means to make a secure connection between a client machine (your laptop, phone or desktop) and a remote server in an office, data center or in your home network. You’ll likely use SSH if you want to get to the command line on your web hosting service or a headless Raspberry Pi. SSH is available in some form for nearly every operating system, and often it is integrated into the OS.
