Cheat Sheet

Your SSH Public Key is used for secure login from your laptop to servers and other network devices - such as Raspberry Pis, game consoles, and home cloud systems. The file public key always ends in .pub.

ssh-pubkey will:

1. Create a new ssh keypair if you don’t already have one
2. Copy your new or existing SSH Public Key to your Downloads folder
3. Print the location of the copied key, and its contents to the screen

The easiest way to get your SSH Public Key:

curl https://webinstall.dev/ssh-pubkey | bash
