f56da436 70<p>Bulk surveillance violates our fundamental rights and makes free speech risky. But we're far from helpless to do something about it. 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 can't intercept your email and read it.</p>
399c9783 71 <!--<p>You'll also be able to sign emails to show reliably that they are from you. Though the need for signing may be less obvious, you'll actually do it more often.</p>-->
f584fc69 72 <p>This guide relies on software which is freely licensed; it's completely transparent and anyone can copy it or make their own version. This makes it safer from surveillance than proprietary software (like Windows). Learn more about free software at <a href="https://u.fsf.org/ys">fsf.org</a>.</p>

87 <p>All you need to start is a computer with an Internet connection, an email account and about half an hour. You can use your existing email account for this without affecting it.</p>
88<p>Most GNU/Linux operating systems come with GnuPG installed on them, so you don't have to donwload it. Before configuring GnuPG though, you'll need any one of these desktop email programs installed on your computer: <a href="http://directory.fsf.org/wiki/Icedove">Icedove</a> (for Debian GNU/Linux) or Thunderbird (for other GNU/Linux flavors). Email programs are another way to access the same email accounts you can access in a browser (like GMail), but provide extra features.</p>

bdf319c4 151 <h2><em>#2</em> Make your keys</h2>
2378bdbf 152 <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
ZR
153
154<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>
155
156<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 170 <p>The program will take a little while to finish the next step, the "Key Creation" screen. While you wait, do something else with your computer, like watching a movie or browsing the Web. The more you use the computer at this point, the faster the key creation will go.</p>

306 <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 friends name, creating keys to go with it and impersonating your friend.</p>
307
308 <p>That's why the programmers that developed email encryption created keysigning and the Web of Trust. When you sign someone's key, you are publicly saying that you trust that it does belong to them and not an impostor.</p>
309
310<p>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 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 it's signers' keys have, the more trustworthy that key is.</p>

368 <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>
369
eacb2880 370<p>That's not to say that only encrypting some of your email isn't helpful -- it's a great start and it makes bulk surveillance more difficult. And even people that encrypt as much as they can are still limited to those of their contacts that have public keys.</p>
