Title: Understanding how git works internally &quot;from the ground up&quot; has been incredibly helpful in my everyday work; things like blobs, commit objects, hashes and how they connect to form the git experience as I know it. Where I had been cargo-culting along previously, it all became clear once I understood the fundamental model of what was going on underneath the interface.<p>I feel like the same thing could apply to PGP&#x2F;GnuPG. I am cargo culting my way along but I feel like I would feel much, much, much more comfortable if I knew how it worked from the ground up.<p>I have loose ideas of asymmetric cryptography and trust circles and such, but nothing concrete to hinge my actions upon, so I mostly try different permutations of command line arguments until GPG appears to do what I want it to do.<p>Is there a &quot;from the ground up&quot; good guide to PGP that allows me to break out of this pattern?
