100Bulk surveillance violates our fundamental rights and makes free speech
101risky. This guide will teach you a basic surveillance self-defense skill: email
102encryption. Once you've finished, you'll be able to send and receive emails
103that are scrambled to make sure a surveillance agent or thief intercepting
104your email can't read them. All you need is a computer with an Internet
105connection, an email account, and about forty minutes.</p>
106
107<p>Even if you have nothing to hide, using encryption helps protect the privacy
108of people you communicate with, and makes life difficult for bulk surveillance
109systems. If you do have something important to hide, you're in good company;
110these are the same tools that whistleblowers use to protect their identities
111while shining light on human rights abuses, corruption, and other crimes.</p>
112
113<p>In addition to using encryption, standing up
114to surveillance requires fighting politically for a <a
115href="https://gnu.org/philosophy/surveillance-vs-democracy.html">reduction
116in the amount of data collected on us</a>, but the essential first step is
117to protect yourself and make surveillance of your communication as difficult
118as possible. This guide helps you do that. It is designed for beginners, but
119if you already know the basics of GnuPG or are an experienced free software
120user, you'll enjoy the advanced tips and the <a href="workshops.html">guide

141<p>Most GNU/Linux operating systems come with GnuPG installed on them, so if you're running one of these systems, you don't have to download it. If you're running macOS or Windows, steps to download GnuPG are below. Before configuring your encryption setup with this guide, though, you'll need a desktop email program installed on your computer. Many GNU/Linux distributions have one installed already, such as Icedove, which may be under the alternate name "Thunderbird." Programs like these are another way to access the same email accounts you can access in a browser (like Gmail), but provide extra features.</p>

239<h3>GnuPG, OpenPGP, what?</h3>
240
241<p>In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP
242are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the
243encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG)
244is the program that implements the standard. Most email programs provide an interface for GnuPG. There is also a newer version of GnuPG, called GnuPG2.</p>

259
260<p>To use the GnuPG system, you'll need a public key and a private key (known
261together as a keypair). Each is a long string of randomly generated numbers
262and letters that are unique to you. Your public and private keys are linked
263together by a special mathematical function.</p>
264
265<p>Your public key isn't like a physical key, because it's stored in the open
266in an online directory called a keyserver. People download it and use it,
267along with GnuPG, to encrypt emails they send to you. You can think of the
268keyserver as a phonebook; people who want to send you encrypted email can
269look up your public key.</p>
270
271<p>Your private key is more like a physical key, because you keep it to
272yourself (on your computer). You use GnuPG and your private key together to
273descramble encrypted emails other people send to you. <strong>You should never share your private key with anyone, under any
274circumstances.</strong></p>
275
276<p>In addition to encryption and decryption, you can also use these keys to
277sign messages and check the authenticity of other people's signatures. We'll
278discuss this more in the next section.</p>

297
298<h4>Make your keypair</h4>
299
300<p>We will use the command line in a terminal to create a keypair using the
301GnuPG program.</p>
302
303<p class="notes">Whether on GNU/Linux, macOS or Windows, you can launch your
304terminal ("Terminal" in macOS, "PowerShell" in Windows) from the Applications
305menu (some GNU/Linux systems respond to the <kbd>Ctrl + Alt + T</kbd>
306shortcut).</p>
307
308<p># Enter <code>gpg --full-generate-key</code> to start the process.</p>
309<p># To answer what kind of key you would like to create, select the default option: <samp>1&nbsp;RSA&nbsp;and&nbsp;RSA</samp>.</p>
310<p># Enter the following keysize: <code>4096</code> for a strong key.</p>
311<p># Choose the expiration date; we suggest <code>2y</code> (2 years).</p>
312<p>Follow the prompts to continue setting up with your personal details.</p>
313<p class="notes"> Depending on your version of GPG, you may need to use <code>--gen-key</code> instead of <code>--full-generate-key</code>.</p>
314
315<h4>Set your passphrase</h4>
316<p>On the screen titled "Passphrase," pick a strong password! You can
317do it manually, or you can use the Diceware method. Doing it manually
318is faster but not as secure. Using Diceware takes longer and requires
319dice, but creates a password that is much harder for attackers to figure
320out. To use it, read the section "Make a secure passphrase with Diceware" in <a
321href="https://theintercept.com/2015/03/26/passphrases-can-memorize-attackers-cant-guess/">
322this article</a> by Micah Lee.</p>
323
324
325<p>If you'd like to pick a passphrase manually, come up with something
326you can remember which is at least twelve characters long, and includes
327at least one lower case and upper case letter and at least one number or
328punctuation symbol. Never pick a password you've used elsewhere. Don't use
329any recognizable patterns, such as birthdays, telephone numbers, pets' names,
330song lyrics, quotes from books, and so on.</p>

337<dt>GnuPG is not installed</dt>
338<dd>
339You can check if this is the case with the command <code>gpg --version</code>&#65279;.
340If GnuPG is not installed, it will bring up the following result on most GNU/Linux operating systems, or something like it:
341<samp>Command 'gpg' not found, but can be installed with:
342 sudo apt install gnupg</samp>. Follow that command and install the program.</dd>
343
344<dt><i>gpg --full-generate-key</i> command not working</dt>
345<dd>Some distributions use a different version of GPG. When you receive an error code that is something along the lines of: <samp>gpg: Invalid option "--full-generate-key"</samp>, you can try the following commands: <br />
346<code>sudo apt update</code><br />
347<code>sudo apt install gnupg2</code><br />
348<code>gpg2 --full-generate-key</code><br />
349If this resolved the issue, you need to continue to use the gpg2 identifier instead of gpg throughout the following steps of the guide.
350<p class="notes"> Depending on your version of GPG, you may need to use <code>--gen-key</code> instead of <code>--full-generate-key</code>.</p></dd>
351
352<dt>I took too long to create my passphrase</dt>
353<dd>That's okay. It's important to think about your passphrase. When you're ready, just follow the steps from the beginning again to create your key.</dd>
354
355<dt>How can I see my key?</dt>
356<dd>
357Use the following command to see all keys: <code>gpg --list-keys</code>&#65279;. Yours should be listed in there, and later, so will Edward's (<a href="#section3">Section 3</a>).<br />
358If you want to see only your key, you can use <code>gpg --list-key [your@email]</code>&#65279;.<br />
359You can also use <code>gpg --list-secret-key</code> to see your own private key.</dd>

364Handbook</a>. Make sure you stick with "RSA and RSA" (the default),
365because it's newer and more secure than the algorithms the documentation

407<h3><em>Step 2.b</em> Some important steps following creation</h3>
408
409<h4>Upload your key to a keyserver</h4>
410<p>We will upload your key to a keyserver, so if someone wants to send you an encrypted message, they can download your public key from the Internet. There are multiple keyservers
411that you can select from the menu when you upload, but they are mostly all copies
412of each other. Any server will work, but it's good to remember which one you uploaded your key to originally. Also keep in mind, sometimes takes a few hours for them to match each other when a new key is uploaded.</p>
413<p># Copy your keyID: <code>gpg --list-key [your@email]</code> will list your public ("pub") key information, including your keyID, which is a unique list of numbers and letters. Copy this keyID, so you can use it in the following command.</p>
414<p># Upload your key to a server:
415<code>gpg --send-key [keyID]</code></p>
416
417<h4>Export your key to a file</h4>
418<p>Use the following command to export your secret key so you can import it into your email client at the next <a href="#section3">step</a>. To avoid getting your key compromised, store this in a safe place, and make sure that if it is transferred, it is done so in a trusted way. Exporting your keys can be done with the following commands:</p>
419<p><code>
420$ gpg --export-secret-keys -a [keyID] > my_secret_key.asc<br/>
421$ gpg --export -a [keyID] > my_public_key.asc
422</code></p>
423
424<h4>Generate a revocation certificate</h4>
425<p>Just in case you lose your key, or it gets compromised, you want to generate a certificate and choose to save it in a safe place on your computer for now (please refer to <a href="#step-6c">Step 6.C</a> for how to best store your revocation cerficate safely). This step is essential for your email self-defense, as you'll learn more about in <a href="#section5">Section 5</a>.</p>
426
427<p># Copy your keyID: <code>gpg --list-key [your@email]</code> will list your public ("pub") key information, including your keyID, which is a unique list of numbers and letters. Copy this keyID, so you can use it in the following command.</p>
428<p># Generate a revocation certificate: <code>gpg --gen-revoke --output revoke.asc [keyID]</code></p>

639
640<h4>Get Edward's key</h4>
641
642<p>To encrypt an email to Edward, you need its public key, so now you'll have
643to download it from a keyserver. You can do this in two different ways:</p>
644<p><strong>Option 1.</strong> In the email answer you received from Edward as a response to your first email, Edward's public key was included. On the right of the email, just above the writing area, you will find an "OpenPGP" button that has a lock and a little wheel next to it. Click that, and select <i>Discover</i> next to the text: "This message was signed with a key that you don't yet have." A popup with Edward's key details will follow.</p>
645
646<p><strong>Option 2.</strong> Open your OpenPGP Key manager, and under "Keyserver" choose <i>Discover Keys Online</i>. Here, fill in Edward's email address, and import Edward's key.</p>
647
648<p>The option <i>Accepted (unverified)</i> will add this key to your key manager, and now it can be used to send encrypted emails and to verify digital signatures from Edward.</p>
649
650<p class="notes">In the popup window confirming if you want to import Edward's key, you'll see many different emails that are all associated with its key. This is correct; you can safely import the key.</p>
651
652<p class="notes">Since you encrypted this email with Edward's public key,
653Edward's private key is required to decrypt it. Edward is the only one with
654its private key, so no one except Edward can decrypt it.</p>
655
656<h4>Send Edward an encrypted email</h4>
657
658<p> Write a new email in your email program, addressed to <a
659href="mailto:edward-en@fsf.org">edward-en@fsf.org</a>. Make the subject
660"Encryption test" or something similar and write something in the body.</p>
661
662<p>This time, make sure encryption is turned on by using the dropdown menu "Security" and select <i>Require Encryption</i>. Once encryption is on, hit Send.</p>

824<p class="float small"><img src="../static/img/en/screenshots/section5-web-of-trust.png" alt="Illustration of keys all interconnected with a web of lines"/></p>
825
826<p>Email encryption is a powerful technology, but it has a weakness:
827it requires a way to verify that a person's public key is actually
828theirs. Otherwise, there would be no way to stop an attacker from making
829an email address with your friend's name, creating keys to go with it, and
830impersonating your friend. That's why the free software programmers that
831developed email encryption created keysigning and the Web of Trust.</p>
832
833<p>When you sign someone's key, you are publicly saying that you've verified
834that it belongs to them and not someone else.</p>
835
836<p>Signing keys and signing messages use the same type of mathematical
837operation, but they carry very different implications. It's a good practice
838to generally sign your email, but if you casually sign people's keys, you
839may accidentally end up vouching for the identity of an imposter.</p>
840
841<p>People who use your public key can see who has signed it. Once you've
842used GnuPG for a long time, your key may have hundreds of signatures. You
843can consider a key to be more trustworthy if it has many signatures from
844people that you trust. The Web of Trust is a constellation of GnuPG users,
845connected to each other by chains of trust expressed through signatures.</p>

893<h3>Identifying keys: Fingerprints and IDs</h3>
894
895<p>People's public keys are usually identified by their key fingerprint,
896which is a string of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8
897(for Edward's key). You can see the fingerprint for your public key, and
898other public keys saved on your computer, by going to OpenPGP Key
899Management in your email program's menu, then right clicking on the key
900and choosing Key Properties. It's good practice to share your fingerprint
901wherever you share your email address, so that people can double-check that
902they have the correct public key when they download yours from a keyserver.</p>
903
904<p class="notes">You may also see public keys referred to by a shorter
905keyID. This keyID is visible directly from the Key Management
906window. These eight character keyIDs were previously used for
907identification, which used to be safe, but is no longer reliable. You
908need to check the full fingerprint as part of verifying you have the
909correct key for the person you are trying to contact. Spoofing, in
910which someone intentionally generates a key with a fingerprint whose
911final eight characters are the same as another, is unfortunately
912common.</p>

921<h3><em>Important:</em> What to consider when signing keys</h3>
922
923<p>Before signing a person's key, you need to be confident that it actually
924belongs to them, and that they are who they say they are. Ideally, this
925confidence comes from having interactions and conversations with them over
926time, and witnessing interactions between them and others. Whenever signing
927a key, ask to see the full public key fingerprint, and not just the shorter
928keyID. If you feel it's important to sign the key of someone you've just
929met, also ask them to show you their government identification, and make
930sure the name on the ID matches the name on the public key.</p>

958
959<p>Everyone uses GnuPG a little differently, but it's important to follow
960some basic practices to keep your email secure. Not following them, you
961risk the privacy of the people you communicate with, as well as your own,
962and damage the Web of Trust.</p>

977<h3>When should I encrypt? When should I sign?</h3>
978
979<p>The more you can encrypt your messages, the better. If you only encrypt
980emails occasionally, each encrypted message could raise a red flag for
981surveillance systems. If all or most of your email is encrypted, people
982doing surveillance won't know where to start. That's not to say that only
983encrypting some of your email isn't helpful -- it's a great start and it
984makes bulk surveillance more difficult.</p>
985
986<p>Unless you don't want to reveal your own identity (which requires other
987protective measures), there's no reason not to sign every message, whether or
988not you are encrypting. In addition to allowing those with GnuPG to verify
989that the message came from you, signing is a non-intrusive way to remind
990everyone that you use GnuPG and show support for secure communication. If you
991often send signed messages to people that aren't familiar with GnuPG, it's
992nice to also include a link to this guide in your standard email signature
993(the text kind, not the cryptographic kind).</p>

1010
1011<p>GnuPG makes email safer, but it's still important to watch out for invalid
1012keys, which might have fallen into the wrong hands. Email encrypted with
1013invalid keys might be readable by surveillance programs.</p>
1014
1015<p>In your email program, go back to the first encrypted email that Edward
1016sent you. Because Edward encrypted it with your public key, it will have a
1017green checkmark a at the top "OpenPGP" button.</p>
1018
1019<p><strong>When using GnuPG, make a habit of glancing at that button. The program
1020will warn you there if you get an email signed with a key that can't
1021be trusted.</strong></p>

1030<h3>Copy your revocation certificate to somewhere safe</h3>
1031
1032<p>Remember when you created your keys and saved the revocation certificate
1033that GnuPG made? It's time to copy that certificate onto the safest storage that you have -- a flash drive, disk, or hard drive stored in a safe place in your home could work, not on a device you carry with you regularly. The safest way we know is actually to print the revocation certificate and store it in a safe place.</p>
1034
1035<p>If your private key ever gets lost or stolen, you'll need this certificate

1046
1047<p>If you lose your private key or someone else gets a hold
1048of it (say, by stealing or cracking your computer), it's
1049important to revoke it immediately before someone else uses
1050it to read your encrypted email or forge your signature. This
1051guide doesn't cover how to revoke a key, but you can follow these <a
1052href="https://www.hackdiary.com/2004/01/18/revoking-a-gpg-key/">instructions</a>.
1053After you're done revoking, make a new key and send an email to everyone
1054with whom you usually use your key to make sure they know, including a copy
1055of your new key.</p>

1066<p>When you use a web browser to access your email, you're using webmail,
1067an email program stored on a distant website. Unlike webmail, your desktop
1068email program runs on your own computer. Although webmail can't decrypt
1069encrypted email, it will still display it in its encrypted form. If you
1070primarily use webmail, you'll know to open your email client when you receive
