key pairs

I saw a tweet recently from an experienced dev who still has to look up how to post a public key to GitHub every time they do it. This stuff isn't hard, but it's harder than it should be, especially considering how useful those keys can be and how much they protect you. You see them when signing your GitHub commits, SSH'ing to your hosts, creating and connecting with a VPN, and more. In this session, we will look at a lot of the ways you can use Public Key Cryptography (and probably are already using it) and why using one key for life for everything is a bad approach. But doing it right can be painful without the right tools. So, we will look at some 100% free and open-source tools for getting this right and how to make everything easier. By the end of this session you will be a Key Pair Pro with learnings that will help you for the rest of your career or even with your home lab.


Having some experience with SSH or Github will be nice.
