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

143 <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>

212 To make things easier, we recommend setting up the third-party package manager "Homebrew" to install GnuPG. Copy the link on the home page of <a href="https://brew.sh/">Homebrew</a> and paste it in Terminal. Click "Enter" and wait for the installation to finalize.<br/>
213 When this is done, install GnuPG by entering the following code in Terminal:<br/>

240 <h3>GnuPG, OpenPGP, what?</h3>
241
242 <p>In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP
243 are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the
244 encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG)
245 is 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>

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

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

339 You can check if this is the case with the command <code>gpg --version</code>&#65279;.

347 <dt>How can I see my key?</dt>
348 <dd>
349 Use 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 />
350 If you want to see only your key, you can use <code>gpg --list-key [your@email]</code>&#65279;.<br />

399 <h3><em>Step 2.b</em> Some important steps following creation</h3>
400
401 <h4>Upload your key to a keyserver</h4>
402 <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
403 that you can select from the menu when you upload, but they are all copies
404 of each other, so it doesn't matter which one you use. However, it sometimes
405 takes a few hours for them to match each other when a new key is uploaded.</p>
406 <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>
407 <p># Upload your key to a server:
408 <code>gpg --send-key [keyID]</code></p>
409
410 <h4>Export your key to a file</h4>
411 <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>
412 <p><code>
413 $ gpg --export-secret-keys -a [keyID] > my_secret_key.asc<br/>
414 $ gpg --export -a [keyID] > my_public_key.asc
415 </code></p>
416
417 <h4>Generate a revocation certificate</h4>
418 <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>
419
420 <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>
421 <p># Generate a revocation certificate: <code>gpg --gen-revoke --output revoke.asc [keyID]</code></p>
422 <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>
423 <p># You don't have to fill in a reason, but you can; then press "Enter" for an empty line, and confirm your selection.</p>

626
627 <h4>Get Edward's key</h4>
628
629 <p>To encrypt an email to Edward, you need its public key, so now you'll have
630 to download it from a keyserver. You can do this in two different ways:</p>
631 <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>
632
633 <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>
634
635 <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>
636
637 <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>
638
639 <p class="notes">Since you encrypted this email with Edward's public key,
640 Edward's private key is required to decrypt it. Edward is the only one with
641 its private key, so no one except Edward can decrypt it.</p>
642
643 <h4>Send Edward an encrypted email</h4>
644
645 <p> Write a new email in your email program, addressed to <a
646 href="mailto:edward-en@fsf.org">edward-en@fsf.org</a>. Make the subject
647 "Encryption test" or something similar and write something in the body.</p>
648
649 <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>

756 <p>GnuPG includes a way for you to sign messages and files, verifying that
757 they came from you and that they weren't tampered with along the way. These
758 signatures are stronger than their pen-and-paper cousins -- they're impossible
759 to forge, because they're impossible to create without your private key
760 (another reason to keep your private key safe).</p>
761
762 <p>You can sign messages to anyone, so it's a great way to make people
763 aware that you use GnuPG and that they can communicate with you securely. If
764 they don't have GnuPG, they will be able to read your message and see your
765 signature. If they do have GnuPG, they'll also be able to verify that your
766 signature is authentic.</p>
767
768 <p>To sign an email to Edward, compose any message to the email address and click the
769 pencil icon next to the lock icon so that it turns gold. If you sign a
770 message, GnuPG may ask you for your password before it sends the message,
771 because it needs to unlock your private key for signing.</p>

813
814 <p>Email encryption is a powerful technology, but it has a weakness:
815 it requires a way to verify that a person's public key is actually
816 theirs. Otherwise, there would be no way to stop an attacker from making
817 an email address with your friend's name, creating keys to go with it, and
818 impersonating your friend. That's why the free software programmers that
819 developed email encryption created keysigning and the Web of Trust.</p>
820
821 <p>When you sign someone's key, you are publicly saying that you've verified
822 that it belongs to them and not someone else.</p>
823
824 <p>Signing keys and signing messages use the same type of mathematical
825 operation, but they carry very different implications. It's a good practice
826 to generally sign your email, but if you casually sign people's keys, you
827 may accidentally end up vouching for the identity of an imposter.</p>
828
829 <p>People who use your public key can see who has signed it. Once you've
830 used GnuPG for a long time, your key may have hundreds of signatures. You
831 can consider a key to be more trustworthy if it has many signatures from
832 people that you trust. The Web of Trust is a constellation of GnuPG users,
833 connected to each other by chains of trust expressed through signatures.</p>

881 <h3>Identifying keys: Fingerprints and IDs</h3>
882
883 <p>People's public keys are usually identified by their key fingerprint,
884 which is a string of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8
885 (for Edward's key). You can see the fingerprint for your public key, and
886 other public keys saved on your computer, by going to OpenPGP Key
887 Management in your email program's menu, then right clicking on the key
888 and choosing Key Properties. It's good practice to share your fingerprint
889 wherever you share your email address, so that people can double-check that
890 they have the correct public key when they download yours from a keyserver.</p>
891
892 <p class="notes">You may also see public keys referred to by a shorter
893 keyID. This keyID is visible directly from the Key Management
894 window. These eight character keyIDs were previously used for
895 identification, which used to be safe, but is no longer reliable. You
896 need to check the full fingerprint as part of verifying you have the
897 correct key for the person you are trying to contact. Spoofing, in
898 which someone intentionally generates a key with a fingerprint whose
899 final eight characters are the same as another, is unfortunately
900 common.</p>

909 <h3><em>Important:</em> What to consider when signing keys</h3>
910
911 <p>Before signing a person's key, you need to be confident that it actually
912 belongs to them, and that they are who they say they are. Ideally, this
913 confidence comes from having interactions and conversations with them over
914 time, and witnessing interactions between them and others. Whenever signing
915 a key, ask to see the full public key fingerprint, and not just the shorter
916 keyID. If you feel it's important to sign the key of someone you've just
917 met, also ask them to show you their government identification, and make
918 sure the name on the ID matches the name on the public key.</p>

946
947 <p>Everyone uses GnuPG a little differently, but it's important to follow
948 some basic practices to keep your email secure. Not following them, you
949 risk the privacy of the people you communicate with, as well as your own,
950 and damage the Web of Trust.</p>

965 <h3>When should I encrypt? When should I sign?</h3>
966
967 <p>The more you can encrypt your messages, the better. If you only encrypt
968 emails occasionally, each encrypted message could raise a red flag for
969 surveillance systems. If all or most of your email is encrypted, people
970 doing surveillance won't know where to start. That's not to say that only
971 encrypting some of your email isn't helpful -- it's a great start and it
972 makes bulk surveillance more difficult.</p>
973
974 <p>Unless you don't want to reveal your own identity (which requires other
975 protective measures), there's no reason not to sign every message, whether or
976 not you are encrypting. In addition to allowing those with GnuPG to verify
977 that the message came from you, signing is a non-intrusive way to remind
978 everyone that you use GnuPG and show support for secure communication. If you
979 often send signed messages to people that aren't familiar with GnuPG, it's
980 nice to also include a link to this guide in your standard email signature
981 (the text kind, not the cryptographic kind).</p>

997 <h3>Be wary of invalid keys</h3>
998
999 <p>GnuPG makes email safer, but it's still important to watch out for invalid
1000 keys, which might have fallen into the wrong hands. Email encrypted with
1001 invalid keys might be readable by surveillance programs.</p>
1002
1003 <p>In your email program, go back to the first encrypted email that Edward
1004 sent you. Because Edward encrypted it with your public key, it will have a
1005 green checkmark a at the top "OpenPGP" button.</p>
1006
1007 <p><strong>When using GnuPG, make a habit of glancing at that button. The program
1008 will warn you there if you get an email signed with a key that can't
1009 be trusted.</strong></p>

1018 <h3>Copy your revocation certificate to somewhere safe</h3>
1019
1020 <p>Remember when you created your keys and saved the revocation certificate
1021 that 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>
1022
1023 <p>If your private key ever gets lost or stolen, you'll need this certificate
1024 file to let people know that you are no longer using that keypair.</p>

1034
1035 <p>If you lose your private key or someone else gets a hold
1036 of it (say, by stealing or cracking your computer), it's
1037 important to revoke it immediately before someone else uses
1038 it to read your encrypted email or forge your signature. This
1039 guide doesn't cover how to revoke a key, but you can follow these <a
1040 href="https://www.hackdiary.com/2004/01/18/revoking-a-gpg-key/">instructions</a>.
1041 After you're done revoking, make a new key and send an email to everyone
1042 with whom you usually use your key to make sure they know, including a copy
1043 of your new key.</p>

1053
1054 <p>When you use a web browser to access your email, you're using webmail,
1055 an email program stored on a distant website. Unlike webmail, your desktop
1056 email program runs on your own computer. Although webmail can't decrypt
1057 encrypted email, it will still display it in its encrypted form. If you
1058 primarily use webmail, you'll know to open your email client when you receive
