GNU Privacy Guard Guide


Getting Started

Crash Course:

The folks at the Free Software Foundation have a pretty good graphic that will work for most people at https://emailselfdefense.fsf.org/en/.
The rest of this guide is mostly about a getting a more secure configuration of GPG in place on your machine (and showcasing more xkcd comics about *nix/crypto)

How to read this guide:

I've tried to keep a consistent format. Here's a quick legend:

Instructions, prose, terrible jokes
Code or command line i/o
Arguments you'll need to provide or code you'll want to update
Hints
Warnings

All of the keys that I've demo'd here are temporary keys that I generated specifically for the purpose of this guide. Please don't try to send me email encrypted with these keys, since I won't be able to read it.

Where to get GnuPG:

GNU/Linux (Debian, Ubuntu, Mint, Fedora, etc)
Your operating system will install GnuPG automatically and keep it up to date for you.

Windows
You can download and install from https://www.gnupg.org/download/. Download the "Simple installer for GnuPG modern"
There is also an implementation called GPG4Win you may want to look into. I could not figure out how to get their UI tool (Kleopatra) to behave with some of the steps I describe later in this guide without storing all of my keys locally, but you may have more luck than I did.

Mac OS You can install GPG suite from GPGTools.

Where to get Claws-mail:

GNU/Linux (Debian, Ubuntu, Mint, Fedora, etc)

	sudo add-apt-repository ppa:claws-mail/ppa
	sudo apt-get update
	sudo apt-get install claws-mail
	sudo apt-get install claws-mail-plugins
				
Windows You can download and install from http://www.claws-mail.org/win32/
