95Bulk surveillance violates our fundamental rights and makes free speech
96risky. This guide will teach you a basic surveillance self-defense skill: email
97encryption. Once you've finished, you'll be able to send and receive emails
98that are scrambled to make sure a surveillance agent or thief intercepting
99your email can't read them. All you need is a computer with an Internet
100connection, an email account, and about forty minutes.</p>
101
102<p>Even if you have nothing to hide, using encryption helps protect the privacy
103of people you communicate with, and makes life difficult for bulk surveillance
104systems. If you do have something important to hide, you're in good company;
105these are the same tools that whistleblowers use to protect their identities
106while shining light on human rights abuses, corruption, and other crimes.</p>
107
108<p>In addition to using encryption, standing up
109to surveillance requires fighting politically for a <a
110href="https://gnu.org/philosophy/surveillance-vs-democracy.html">reduction
111in the amount of data collected on us</a>, but the essential first step is
112to protect yourself and make surveillance of your communication as difficult
113as possible. This guide helps you do that. It is designed for beginners, but
114if you already know the basics of GnuPG or are an experienced free software
115user, you'll enjoy the advanced tips and the <a href="workshops.html">guide

136<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>

235
236<p>In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP
237are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the
238encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG)
239is 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>

254
255<p>To use the GnuPG system, you'll need a public key and a private key (known
256together as a keypair). Each is a long string of randomly generated numbers
257and letters that are unique to you. Your public and private keys are linked
258together by a special mathematical function.</p>
259
260<p>Your public key isn't like a physical key, because it's stored in the open
261in an online directory called a keyserver. People download it and use it,
262along with GnuPG, to encrypt emails they send to you. You can think of the
263keyserver as a phonebook; people who want to send you encrypted email can
264look up your public key.</p>
265
266<p>Your private key is more like a physical key, because you keep it to
267yourself (on your computer). You use GnuPG and your private key together to
268descramble encrypted emails other people send to you. <strong>You should never share your private key with anyone, under any
269circumstances.</strong></p>
270
271<p>In addition to encryption and decryption, you can also use these keys to
272sign messages and check the authenticity of other people's signatures. We'll
273discuss this more in the next section.</p>

292
293<h4>Make your keypair</h4>
294
295<p>We will use the command line in a terminal to create a keypair using the
296GnuPG program.</p>
297
298<p class="notes">Whether on GNU/Linux, macOS or Windows, you can launch your
299terminal ("Terminal" in macOS, "PowerShell" in Windows) from the Applications
300menu (some GNU/Linux systems respond to the <kbd>Ctrl + Alt + T</kbd>
301shortcut).</p>
302
303<p># Enter <code>gpg --full-generate-key</code> to start the process.</p>
304<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>
305<p># Enter the following keysize: <code>4096</code> for a strong key.</p>
306<p># Choose the expiration date; we suggest <code>2y</code> (2 years).</p>
307<p>Follow the prompts to continue setting up with your personal details.</p>
308<p class="notes"> Depending on your version of GPG, you may need to use
309<code>--gen-key</code> instead of <code>--full-generate-key</code>&#65279;.</p>
310
311<h4>Set your passphrase</h4>
312<p>On the screen titled "Passphrase," pick a strong passphrase! You can
313do it manually, or you can use the Diceware method. Doing it manually
314is faster but not as secure. Using Diceware takes longer and requires
315dice, but creates a passphrase that is much harder for attackers to figure
316out. To use it, read the section "Make a secure passphrase with Diceware" in <a
317href="https://theintercept.com/2015/03/26/passphrases-can-memorize-attackers-cant-guess/">
318this article</a> by Micah Lee.</p>
319
320
321<p>If you'd like to pick a passphrase manually, come up with something
322you can remember which is at least twelve characters long, and includes
323at least one lower case and upper case letter and at least one number or
324punctuation symbol. Never pick a passphrase you've used elsewhere. Don't use
325any recognizable patterns, such as birthdays, telephone numbers, pets' names,
326song lyrics, quotes from books, and so on.</p>

333<dt>GnuPG is not installed</dt>
334<dd>
335You can check if this is the case with the command <code>gpg --version</code>&#65279;.
336If GnuPG is not installed, it will bring up the following result on most GNU/Linux operating systems, or something like it:
337<samp>Command 'gpg' not found, but can be installed with:
338 sudo apt install gnupg</samp>. Follow that command and install the program.</dd>
339
340<dt><i>gpg --full-generate-key</i> command not working</dt>
341<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 />
342<code>sudo apt update</code><br />
343<code>sudo apt install gnupg2</code><br />
344<code>gpg2 --full-generate-key</code><br />
345If this resolved the issue, you need to continue to use the gpg2 identifier instead of gpg throughout the following steps of the guide.
346<p class="notes"> Depending on your version of GPG, you may need to use

405<h3><em>Step 2.b</em> Some important steps following creation</h3>
406
407<h4>Upload your key to a keyserver</h4>
408<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
409that you can select from the menu when you upload, but they are mostly all copies
410of 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>
411<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>
412<p># Upload your key to a server:
413<code>gpg --send-key [keyID]</code></p>
414
415<h4>Export your key to a file</h4>
416<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>
417<p><code>
418$ gpg --export-secret-keys -a [keyID] > my_secret_key.asc<br/>
419$ gpg --export -a [keyID] > my_public_key.asc
420</code></p>
421
422<h4>Generate a revocation certificate</h4>
423<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>
424
425<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>
426<p># Generate a revocation certificate: <code>gpg --gen-revoke --output revoke.asc [keyID]</code></p>
427<p># It will prompt you to give a reason for revocation, we recommend to use <samp>1&nbsp;=&nbsp;key has been compromised</samp>.</p>

635
636<h4>Get Edward's key</h4>
637
638<p>To encrypt an email to Edward, you need its public key, so now you'll have
639to download it from a keyserver. You can do this in two different ways:</p>
640<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>
641
642<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>
643
644<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>
645
646<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>
647
648<p class="notes">Since you encrypted this email with Edward's public key,
649Edward's private key is required to decrypt it. Edward is the only one with
650its private key, so no one except Edward can decrypt it.</p>
651
652<h4>Send Edward an encrypted email</h4>
653
654<p> Write a new email in your email program, addressed to <a
655href="mailto:edward-en@fsf.org">edward-en@fsf.org</a>. Make the subject
656"Encryption test" or something similar and write something in the body.</p>
657
658<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>

820<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>
821
822<p>Email encryption is a powerful technology, but it has a weakness:
823it requires a way to verify that a person's public key is actually
824theirs. Otherwise, there would be no way to stop an attacker from making
825an email address with your friend's name, creating keys to go with it, and
826impersonating your friend. That's why the free software programmers that
827developed email encryption created keysigning and the Web of Trust.</p>
828
829<p>When you sign someone's key, you are publicly saying that you've verified
830that it belongs to them and not someone else.</p>
831
832<p>Signing keys and signing messages use the same type of mathematical
833operation, but they carry very different implications. It's a good practice
834to generally sign your email, but if you casually sign people's keys, you
835may accidentally end up vouching for the identity of an imposter.</p>
836
837<p>People who use your public key can see who has signed it. Once you've
838used GnuPG for a long time, your key may have hundreds of signatures. You
839can consider a key to be more trustworthy if it has many signatures from
840people that you trust. The Web of Trust is a constellation of GnuPG users,
841connected to each other by chains of trust expressed through signatures.</p>

864a real person, but it's good practice, and for real people it is important. You can read more about signing a person's key in the <a href="#check-ids-before-signing">check IDs before signing</a> section.</p>

889<h3>Identifying keys: Fingerprints and IDs</h3>
890
891<p>People's public keys are usually identified by their key fingerprint,
892which is a string of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8
893(for Edward's key). You can see the fingerprint for your public key, and
894other public keys saved on your computer, by going to OpenPGP Key
895Management in your email program's menu, then right clicking on the key
896and choosing Key Properties. It's good practice to share your fingerprint
897wherever you share your email address, so that people can double-check that
898they have the correct public key when they download yours from a keyserver.</p>
899
900<p class="notes">You may also see public keys referred to by a shorter
901keyID. This keyID is visible directly from the Key Management
902window. These eight character keyIDs were previously used for
903identification, which used to be safe, but is no longer reliable. You
904need to check the full fingerprint as part of verifying you have the
905correct key for the person you are trying to contact. Spoofing, in
906which someone intentionally generates a key with a fingerprint whose
907final eight characters are the same as another, is unfortunately
908common.</p>

917<h3><em>Important:</em> What to consider when signing keys</h3>
918
919<p>Before signing a person's key, you need to be confident that it actually
920belongs to them, and that they are who they say they are. Ideally, this
921confidence comes from having interactions and conversations with them over
922time, and witnessing interactions between them and others. Whenever signing
923a key, ask to see the full public key fingerprint, and not just the shorter
924keyID. If you feel it's important to sign the key of someone you've just
925met, also ask them to show you their government identification, and make
926sure the name on the ID matches the name on the public key.</p>

954
955<p>Everyone uses GnuPG a little differently, but it's important to follow
956some basic practices to keep your email secure. Not following them, you
957risk the privacy of the people you communicate with, as well as your own,
958and damage the Web of Trust.</p>

973<h3>When should I encrypt? When should I sign?</h3>
974
975<p>The more you can encrypt your messages, the better. If you only encrypt
976emails occasionally, each encrypted message could raise a red flag for
977surveillance systems. If all or most of your email is encrypted, people
978doing surveillance won't know where to start. That's not to say that only
979encrypting some of your email isn't helpful -- it's a great start and it
980makes bulk surveillance more difficult.</p>
981
982<p>Unless you don't want to reveal your own identity (which requires other
983protective measures), there's no reason not to sign every message, whether or
984not you are encrypting. In addition to allowing those with GnuPG to verify
985that the message came from you, signing is a non-intrusive way to remind
986everyone that you use GnuPG and show support for secure communication. If you
987often send signed messages to people that aren't familiar with GnuPG, it's
988nice to also include a link to this guide in your standard email signature
989(the text kind, not the cryptographic kind).</p>

1005<h3>Be wary of invalid keys</h3>
1006
1007<p>GnuPG makes email safer, but it's still important to watch out for invalid
1008keys, which might have fallen into the wrong hands. Email encrypted with
1009invalid keys might be readable by surveillance programs.</p>
1010
1011<p>In your email program, go back to the first encrypted email that Edward
1012sent you. Because Edward encrypted it with your public key, it will have a
1013green checkmark on the "OpenPGP" button.</p>
1014
1015<p><strong>When using GnuPG, make a habit of glancing at that button. The program
1016will warn you there if you get an email signed with a key that can't
1017be trusted.</strong></p>

1026<h3>Copy your revocation certificate to somewhere safe</h3>
1027
1028<p>Remember when you created your keys and saved the revocation certificate
1029that 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>
1030
1031<p>If your private key ever gets lost or stolen, you'll need this certificate
1032file to let people know that you are no longer using that keypair.</p>

1042
1043<p>If you lose your private key or someone else gets a hold
1044of it (say, by stealing or cracking your computer), it's
1045important to revoke it immediately before someone else uses
1046it to read your encrypted email or forge your signature. This
1047guide doesn't cover how to revoke a key, but you can follow these <a
1048href="https://www.hackdiary.com/2004/01/18/revoking-a-gpg-key/">instructions</a>.
1049After you're done revoking, make a new key and send an email to everyone
1050with whom you usually use your key to make sure they know, including a copy
1051of your new key.</p>

1060<h3>Webmail and GnuPG</h3>
1061
1062<p>When you use a web browser to access your email, you're using webmail,
1063an email program stored on a distant website. Unlike webmail, your desktop
1064email program runs on your own computer. Although webmail can't decrypt
1065encrypted email, it will still display it in its encrypted form. If you
1066primarily use webmail, you'll know to open your email client when you receive
1067a scrambled email.</p>
