1b319a0f 56 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 coded to make sure that a surveillance agent or thief that intercepts your email can't read it. All you need is a computer with an Internet connection, an email account and about half an hour.</p>

58<p>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 Edward Snowden used to share his famous secrets about the NSA.</p>
59
8015decf 60<p>In addition to using encryption, standing up to surveillance requires fighting politically for a <a href="http://gnu.org/philosophy/surveillance-vs-democracy.html">reduction in the amount of data collected on us</a>, but the essential first step is to protect yourself and make surveillance of your communication as difficult as possible. Let's get started!</p>

75<p>Most GNU/Linux operating systems come with GnuPG installed on them, so you don't have to download it. Before configuring GnuPG though, you'll need a desktop email program installed on your computer. Most GNU/Linux distributions have a free software version of the Thunderbird email program available to install. This guide will work with them, in addition to Thunderbird itself. Email programs are another way to access the same email accounts you can access in a browser (like GMail), but provide extra features.</p>

2378bdbf 139 <p>To use the GnuPG system, you'll need a public key and a private key (known together as a keypair). Each is a long string of randomly generated numbers that are unique to you. Your public and private keys are linked together by a special mathematical function.</p>
f56da436

140
141<p>Your public key isn't like a physical key, because it's stored in the open in an online directory called a keyserver. People download it and use it, along with GnuPG, to encrypt emails they send to you. You can think of the keyserver as phonebook, where people who want to send you an encrypted email look up your public key.</p>
142
143<p>Your private key is more like a physical key, because you keep it to yourself (on your computer). You use GnuPG and your private key to decode encrypted emails other people send to you.</p>

2378bdbf 296 <h2><em>#4</em> Learn the Web of Trust</h2>
b0ce405b 297 <p>Email encryption is a powerful technology, but it has a weakness; it requires a way to verify that a person's public key is actually theirs. Otherwise, there would be no way to stop an attacker from making an email address with your friend's name, creating keys to go with it and impersonating your friend. That's why the free software programmers that developed email encryption created keysigning and the Web of Trust.</p>
eacb2880 298
b0ce405b 299<p>When you sign someone's key, you are publicly saying that you trust that it does belong to them and not an impostor. People who use your public key can see the number of signatures it has. Once you've used GnuPG for a long time, you may have hundreds of signatures. The Web of Trust is the constellation of all GnuPG users, connected to each other by chains of trust expressed through signatures, into a giant Web. The more signatures a key has, and the more signatures its signers' keys have, the more trustworthy that key is.</p>
eacb2880 300
19d4fe06 301<p>People's public keys are usually identified by their key fingerprint, which is a string of digits like DD878C06E8C2BEDDD4A440D3E573346992AB3FF7 (for Adele's key). You can see the fingerprint for your public key, and other public keys saved on your computer, by going to OpenPGP &rarr; Key Management in your email program's menu, then right clicking on the key and choosing Key Properties. It's good practice to share your fingerprint wherever you share your email address, so that so that people can double-check that they have the correct public key when they download yours from a keyserver.</p>
6ce3ff70 302
19d4fe06 303<p>You may also see public keys referred to by their key ID, which is simply the last 8 digits of the fingerprint, like 92AB3FF7 for Adele. The key ID is visible directly from the Key Management Window. This key ID is like a person's first name (it is a useful shorthand but may not be unique to a given key), whereas the fingerprint actually identifies the key uniquely without the possibility of confusion.</p>

362 <p>The more you can encrypt your messages, the better. This is because, if you only encrypt emails occasionally, each encrypted message could raise a red flag for surveillance systems. If all or most of your email is encrypted, people doing surveillance won't know where to start.</p>
