e91bc017 95 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 scrambed to make sure a surveillance agent or thief intercepting your email can't read it. All you need is a computer with an Internet connection, an email account, about forty minutes and five dice (optional, but recommended).</p>

97<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>
98
7fe1d11a 99<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. This guide helps you do that. If you're just starting out, don't worry about reading the "advanced" tips; they're completely non-essential to getting you up and running. Let's get started!</p>

57f57e85 114<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 the IceDove desktop email program installed on your computer. Most GNU/Linux distributions have IceDove installed already, though it may be under the alternate name "Thunderbird." Email programs are another way to access the same email accounts you can access in a browser (like Gmail), but provide extra features.</p>

e91bc017 125 <p>Open your email program and follow the wizard (step-by-step walkthrough) that sets it up with your email account. Look for the letters SSL, TLS, or STARTTLS to the right of the servers when you're setting up your account. If you don't see them, you will still be able to use encryption, but this means that the people running your email system are running behind the industry standard in protecting your security and privacy. We recommend that you send them a friendly email asking them to enable SSL, TLS, or STARTTLS for your email server. They will know what you're talking about, so it's worth making the request even if you aren't an expert on these security systems.</p>

bbfaa44d 183 <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 and letters that are unique to you. Your public and private keys are linked together by a special mathematical function.</p>
f56da436 184
e91bc017 185 <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 a phonebook; people who want to send you encrypted email can look up your public key.</p>
f56da436 186
385f1ec7 187 <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 descramble encrypted emails other people send to you. <span style="font-weight: bold;">You should never share you public key with anyone, under any circumstances.</span></p>
e91bc017 188 <p>In addition to encryption and decryption, you can also use these keys to sign messages and check the authenticity of other people's signatures. This process helps stop impersonators. We'll discuss this more in the next section.</p>

e91bc017 198 <p>The Enigmail Setup wizard may start automatically. If it doesn't, select Enigmail &rarr; Setup Wizard from your email program's menu. You don't need to read the text in the window that pops up unless you'd like to, but it's good to read the text on the later screens of the wizard.

a9b758ff 202 <li>On the screen titled "Key Selection," select "I want to create a new key pair for signing and encrypting my email."</li>
d1f2c9f6
ZR
203 <li>On the screen titled "Create Key," pick a strong password! We recommend the Diceware method, which creates passwords which are both strong and memorable. To use the Diceware method, you will need dice and this <a href="http://world.std.com/~reinhold/diceware.wordlist.asc">list of words</a>. Do not substitute computer dice for physical dice. Notice that each word on the word list corresponds to a unique five-digit number. Roll one die five times, or five dice once, then string the numbers on the dice dice together to create a five-digit number, and then look up the corresponding word.</li>
204 <li>Repeat this process until you have at least six words, separating each with a space and keeping them all lowercase. You'll end up with a password like "dog help people drive match ice." Don't rearrange or discard the words, because doing so makes the process much less secure.</li>
205 <li>Diceware passwords are hard to remember until you've typed them in a handful of times. Write down your password and keep it with you at all times until you've got it memorized. Then, destroy the piece of paper.</li>
35ff58b1 206 <li>If you don't have dice, pick a password which is at least twelve characters long, and includes at least one lower case and upper case letter and at least one number or punctuation symbol. Never pick a password you've used elsewhere. Don't use any recognizable patterns, such as birthdays, telephone numbers, pets' names, song lyrics, quotes from books, and so on. Don't forget your password, or all of this work will be wasted!</li>
a632ae17 207</ul>
034f3546 208 <p class="notes">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>
688dc100 209 <p><span style="font-weight: bold;">When the "Key Generation Completed" screen pops up, select Generate Certificate and choose to save it in a safe place on your computer (we recommend making a folder called "Revocation Certificate" in your home folder and keeping it there). This step is essential for your email self-defense, as you'll learn more about in <a href="#section5">Section 5</a>.</span></p>

2ba31b7b 292 <p>In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG) is the program that implements the standard.

2378bdbf 420 <h2><em>#4</em> Learn the Web of Trust</h2>
b0ce405b 421 <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 422
f62c428c
AL
423<p>When you sign someone's key, you are publicly saying that you've verified that it belongs to them and not an impostor. Signing keys and messages is the same type mathematical operation, but they carry very different implications. It's a good practice to generally sign your email, but if you casually sign people's keys, you may accidently end up vouching for the identity of an imposter!</p>
424
425<p>People who use your public key can see who has signed it. Once you've used GnuPG for a long time, you may have hundreds of signatures. The Web of Trust is a constellation of GnuPG users, connected to each other by chains of trust expressed through signatures. The more signatures of people you trust a key has, the more trustworthy that key is.</p>

c5025a0e

460 <p>People's public keys are usually identified by their key fingerprint, which is a string of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8 (for Edward's key). You can see the fingerprint for your public key, and other public keys saved on your computer, by going to Enigmail &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 people can double-check that they have the correct public key when they download yours from a keyserver.</p>
461
e91bc017 462<p class="notes">You may also see public keys referred to by their key ID, which is simply the last eight digits of the fingerprint, like C09A61E8 for Edward. 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. If you only have the key ID, you can still look up the key (as well as its fingerprint), like you did in Step 3, but if multiple options appear, you'll need the fingerprint of the person to whom you are trying to communicate to verify which one to use.</p>

In Enigmail, answer honestly in the window that pops up and asks "How carefully have you verified that the key you are about to sign actually belongs to the person(s) named above?".</p>

532 <p>Remember when you created your keys and saved the revocation certificate that GnuPG made? It's time to copy that certificate onto the safest digital storage that you have -- the ideal thing is a flash drive, disk, or hard drive stored in a safe place in your home.</p>
533<p>If your private key ever gets lost or stolen, you'll need this certificate file to let people know that you are no longer using that keypair.</p>

540 <h3><em>Important:</em> act swiftly if someone gets your private key</h3>
d1f2c9f6 541 <p>If you lose your private key or someone else gets ahold of it (say, by stealing or cracking your computer), it's important to revoke it immediately before someone else uses it to read your encrypted email or forge your signature. This guide doesn't cover how to revoke a key, but you can follow the <a href="https://www.gnupg.org/gph/en/manual.html#AEN305">instructions on the GnuPG site</a>. After you're done revoking, send an email to everyone with whom you usually use your key to make sure they know.</p>

b91b170c 551 <p>You can use Enigmail's <a href="https://www.enigmail.net/documentation/keyman.php">key management window</a> to import and export keys. If you want to be able to read your encrypted email on a different computer, you will need to export your secret key from here.

562 <p>When you use a web browser to access your email, you're using webmail, an email program stored on a distant website. Unlike webmail, your desktop email program runs on your own computer. Although webmail can't decrypt encrypted email, it will still display it in its encrypted form. If you primarily use webmail, you'll know to open your email client when you receive a scrambled email.</p>

(At the Free Software Foundation, we put ours on our <a href="https://fsf.org/about/staff">staff page</a>.)
