Can I re-use SSH keys?
I just created a droplet for the first time (and this is my first time with any server). I'm now on the SSH keys page https://www.digitalocean.com/ssh_keys, where the first instruction tells us to check if SSH keys exist, and then it gives instructions for generating new SSH keys. In my case, using the command that the instructions gave, I discovered that I already have SSH keys (which I'm guessing I generated when I signed up for github or heroku) Questions 1) Should I reuse this SSH keys or generate new keys? 2) The instructions talk about adding SSH keys to digital ocean and then creating a server. In my case, I created the droplet before adding SSH keys. Will this create any kind of problem I should be aware of?
