I'm new to this and trying to understand, so bear with me.
I set up a droplet on Digital Ocean and configured SSH keys per Digital Ocean's tutorial. This required running
ssh-keygen -t rsa on my laptop and then providing my Digital Ocean droplet with the public key.
My understanding is that these private and public keys were generated on my laptop; in other words, if my laptop were damaged/stolen, my private key would be gone forever (don't worry, I have a backup that I printed out and stored away safely). However, my question is this: is this private key accessible to someone who is able to access my Wi-Fi network?
