Learn at very minimum how to encrypt and decrypt with PGP
Discussion
I'm a bit of a poser since I don't know how to do it myself. I do know generally how it works, just haven't had a use case for it for myself. One of these days, I'm just going to sit down and give it a try.
Its actually pretty simple stuff, wouldn't take long to get just the basics down.
