I’m confused. I make a unique private key for each machine I use. How is using that machine-specific key on multiple hosts insecure?

- dolmen 3y agoYour SSH public keys used on GitHub are very publicly exposed. This information could be used by SSH servers you are connecting to. You might think you are connecting anonymously, while in fact your SSH client is sending your public key which could then be resolved to your GitHub account.
