This week’s TechMail is Get started with GnuPG, a quick primer on another of my favourite tools: GnuPG. Learn the basics of getting your own GPG keypair created and learn a little bit about fingerprints and signatures and what they all mean.
And if you want to get more into the guts and glory of using GPG, you can read the article I wrote quite a few years ago on Using GnuPG. Like a few of the other articles on linsec.ca, that one could probably do with a bit of a refresher, but I don’t think any of it is necessarily out-dated.
