GnuPG for people that don't like GnuPG

So for some reason you have to use GnuPG (GPG for shorts). It may because you work somewhere with minimal privacy/security conscience, or just because you are on a project that decided to sign commits using a GPG/PGP key (I will use PGP/GPG key interchangeably here). The problem is, you have no idea of what you should be doing. Fear not, you can totally fake it until you make it with a few easy commands.
