SSH keys are like special passcodes for safely talking to computers. As more computers and people start chatting, keeping track of these passcodes becomes tricky. We're going to share smart ways to handle these keys, making things safe and easy.
The Key Challenge

Ways to Share Keys
- Do It Yourself: The old-school way, copying and pasting keys by hand. It works for a few computers but gets messy with more.
- Use Automation Tools: Like having robots help, tools such as Ansible or Puppet can share keys across many computers, making life easier.
- Create an SSH Key Club: For big teams, setting up a club (SSH Certificate Authority) means one approval lets you in everywhere, avoiding the need to share individual keys.
