Bulk surveillance violates our fundamental rights and makes free speech risky. This guide will teach you a basic surveillance self-defense skill: email encryption. Once you've finished, you'll be able to send and receive emails that are scrambled to make sure a surveillance agent or thief intercepting your email can't read them. All you need is a computer with an Internet connection, an email account, and about forty minutes.
Even if you have nothing to hide, using encryption helps protect the privacy of people you communicate with, and makes life difficult for bulk surveillance systems. If you do have something important to hide, you're in good company; these are the same tools that whistleblowers use to protect their identities while shining light on human rights abuses, corruption and other crimes.
In addition to using encryption, standing up to surveillance requires fighting politically for a reduction in the amount of data collected on us, but the essential first step is to protect yourself and make surveillance of your communication as difficult as possible. This guide helps you do that. It is designed for beginners, but if you already know the basics of GnuPG or are an experienced free software user, you'll enjoy the advanced tips and the guide to teaching your friends.
