 518 Bulk surveillance violates our fundamental rights and makes free speech
 519 risky. This guide will teach you a basic surveillance self-defense skill: email
 520 encryption. Once you've finished, you'll be able to send and receive emails
 521 that are scrambled to make sure a surveillance agent or thief intercepting
 522 your email can't read them. All you need is a computer with an Internet
 523 connection, an email account, and about forty minutes.</p>
 524
 525 <p>Even if you have nothing to hide, using encryption helps protect the privacy
 526 of people you communicate with, and makes life difficult for bulk surveillance
 527 systems. If you do have something important to hide, you're in good company;
 528 these are the same tools that whistleblowers use to protect their identities
 529 while shining light on human rights abuses, corruption, and other crimes.</p>
 530
 531 <p>In addition to using encryption, standing up
 532 to surveillance requires fighting politically for a <a
 533 href="https://gnu.org/philosophy/surveillance-vs-democracy.html">reduction
 534 in the amount of data collected on us</a>, but the essential first step is
 535 to protect yourself and make surveillance of your communication as difficult
 536 as possible. This guide helps you do that. It is designed for beginners, but
 537 if you already know the basics of GnuPG or are an experienced free software
 538 user, you'll enjoy the advanced tips and the <a href="workshops.html">guide
 539 to teaching your friends</a>.</p>

 559 <p>Most GNU/Linux operating systems come with GnuPG installed on them,
 560 so you don't have to download it. Before configuring your encryption setup with this guide, though, you'll need a desktop email program based on Thunderbird installed on your computer. Many GNU/Linux distributions have Thunderbird installed already. If you're using a <a href="https://www.gnu.org/distros/free-distros.html">fully free distribution of GNU/Linux</a>,  we recommend installing "Icedove" instead. 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>

 661
 662 <p>In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP
 663 are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the
 664 encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG)
 665 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>

 680
 681 <p>To use the GnuPG system, you'll need a public key and a private key (known
 682 together as a keypair). Each is a long string of randomly generated numbers
 683 and letters that are unique to you. Your public and private keys are linked
 684 together by a special mathematical function.</p>
 685
 686 <p>Your public key isn't like a physical key, because it's stored in the open
 687 in an online directory called a keyserver. People download it and use it,
 688 along with GnuPG, to encrypt emails they send to you. You can think of the
 689 keyserver as a phonebook; people who want to send you encrypted email can
 690 look up your public key.</p>
 691
 692 <p>Your private key is more like a physical key, because you keep it to
 693 yourself (on your computer). You use GnuPG and your private key together to
 694 descramble encrypted emails other people send to you. <span style="font-weight:
 695 bold;">You should never share your private key with anyone, under any
 696 circumstances.</span></p>
 697
 698 <p>In addition to encryption and decryption, you can also use these keys to
 699 sign messages and check the authenticity of other people's signatures. We'll
 700 discuss this more in the next section.</p>

 719 <h3><em>Step 2.a</em> Make a keypair</h3>
 720 <h6>Make your keypair</h6>
 721 <p>We will use the command line to create a keypair using the gnupg program. This should be installed on your GNU/Linux operating system.
 722 Open a terminal using <text style="color:#2f5faa; font-family: monospace;">ctrl + alt + t</text>, or find it in your applications, and use the following code to create your keypair:</p>
 723
 724 <p># <text style="color:#2f5faa; font-family: monospace;">gpg --full-generate-key</text> to start the process.</p>
 725 <p># To answer what kind of key you would like to create, select the default option <text style="color:#2f5faa; font-family: monospace;"> 1 RSA and RSA<text>.</p>
 726 <p># Enter the following keysize: <text style="color:#2f5faa; font-family: monospace;">4096</text> for a strong key.</p>
 727 <p># Choose the expiration date, we suggest <text style="color:#2f5faa; font-family: monospace;">2y</text> (2 years).</p>
 728 <p>Follow the prompts to continue setting up with your personal details.</p>
 729
 730 <br />
 731 <h6>Set your passphrase</h6>
 732 <p>On the screen titled "Passphrase," pick a strong password! You can
 733 do it manually, or you can use the Diceware method. Doing it manually
 734 is faster but not as secure. Using Diceware takes longer and requires
 735 dice, but creates a password that is much harder for attackers to figure
 736 out. To use it, read the section "Make a secure passphrase with Diceware" in <a
 737 href="https://theintercept.com/2015/03/26/passphrases-can-memorize-attackers-cant-guess/">
 738 this article</a> by Micah Lee.</p>
 739
 740
 741 <p>If you'd like to pick a passphrase manually, come up with something
 742 you can remember which is at least twelve characters long, and includes
 743 at least one lower case and upper case letter and at least one number or
 744 punctuation symbol. Never pick a password you've used elsewhere. Don't use
 745 any recognizable patterns, such as birthdays, telephone numbers, pets' names,
 746 song lyrics, quotes from books, and so on.</p>

 815 <h3><em>Step 2.b</em> Some important steps following creation</h3>
 816
 817 <h6>Upload your key to a keyserver</h6>
 818 <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
 819 that you can select from the menu when you upload, but they are all copies
 820 of each other, so it doesn't matter which one you use. However, it sometimes
 821 takes a few hours for them to match each other when a new key is uploaded.</p>
 822 <p># Copy your keyID <text style="color:#2f5faa; font-family: monospace;">gnupg --list-key [your@email]</text> 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>
 823 <p># Upload your key to a server: <text style="color:#2f5faa; font-family: monospace;">gpg --send-key [keyID]</text></p>
 824
 825 <br />
 826
 827 <h6>Export your key to a file</h6>
 828 <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>
 829
 830 <text style="color:#2f5faa; font-family: monospace;">
 831 <p>$ gpg --export-secret-keys -a keyid > my_secret_key.asc</p>
 832 <p>$ gpg --export -a keyid > my_public_key.asc</p>
 833 </text>
 834
 835 <br />
 836

 838 <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 for how to best store your revocation cerficate safely).

1047 <h6>Get Edward's key</h6>
1048 <p>To encrypt an email to Edward, you need its public key, so now you'll have
1049 to download it from a keyserver. You can do this in two different ways:</p>
1050 <p>Option 1. 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 <text style="color:#2f5faa">Discover</text> next to the text: "This message was sent with a key that you don't have yet." A popup with Edward's key details will follow.
1051
1052 <p>Option 2. Open your OpenPGP manager and under "Keyserver" choose <text style="color:#2f5faa">Discover Keys Online</text>. Here, fill in Edward's email address, and import Edward's key.
1053
1054 <p>The option <text style="color:#2f5faa">Accepted (unverified)</text> 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>
1055
1056 <p class="notes">Edward has many different emails associated with its key, you can safely import the key.</p>
1057
1058 <p class="notes">Since you encrypted this email with Edward's public key,
1059 Edward's private key is required to decrypt it. Edward is the only one with
1060 its private key, so no one except Edward can decrypt it.</p>
1061
1062 <br />
1063 <h6>Send Edward an encrypted email</h6>
1064
1065 <p> Write a new email in your email program, addressed to <a
1066 href="mailto:edward-en@fsf.org">edward-en@fsf.org</a>. Make the subject
1067 "Encryption test" or something similar and write something in the body.</p>
1068
1069 <p>This time, make sure encryption is turned on by using the drowpdown menu "Security" and select <text style="color:#2f5faa">Require Encryption</text>. Once encryption is on, hit Send.</p>

1240 developed email encryption created keysigning and the Web of Trust.</p>
1241
1242 <p>When you sign someone's key, you are publicly saying that you've verified
1243 that it belongs to them and not someone else.</p>
1244
1245 <p>Signing keys and signing messages use the same type of mathematical
1246 operation, but they carry very different implications. It's a good practice
1247 to generally sign your email, but if you casually sign people's keys, you
1248 may accidently end up vouching for the identity of an imposter.</p>
1249
1250 <p>People who use your public key can see who has signed it. Once you've
1251 used GnuPG for a long time, your key may have hundreds of signatures. You
1252 can consider a key to be more trustworthy if it has many signatures from
1253 people that you trust. The Web of Trust is a constellation of GnuPG users,
1254 connected to each other by chains of trust expressed through signatures.</p>

1302 <h3>Identifying keys: Fingerprints and IDs</h3>
1303
1304 <p>People's public keys are usually identified by their key fingerprint,
1305 which is a string of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8
1306 (for Edward's key). You can see the fingerprint for your public key, and
1307 other public keys saved on your computer, by going to OpenPGP Key
1308 Management in your email program's menu, then right clicking on the key
1309 and choosing Key Properties. It's good practice to share your fingerprint
1310 wherever you share your email address, so that people can double-check that
1311 they have the correct public key when they download yours from a keyserver.</p>
1312
1313 <p class="notes">You may also see public keys referred to by a shorter
1314 keyID. This keyID is visible directly from the Key Management
1315 window. These eight character keyIDs were previously used for
1316 identification, which used to be safe, but is no longer reliable. You
1317 need to check the full fingerprint as part of verifying you have the
1318 correct key for the person you are trying to contact. Spoofing, in
1319 which someone intentionally generates a key with a fingerprint whose
1320 final eight characters are the same as another, is unfortunately
1321 common.</p>

1330 <h3><em>Important:</em> What to consider when signing keys</h3>
1331
1332 <p>Before signing a person's key, you need to be confident that it actually
1333 belongs to them, and that they are who they say they are. Ideally, this
1334 confidence comes from having interactions and conversations with them over
1335 time, and witnessing interactions between them and others. Whenever signing
1336 a key, ask to see the full public key fingerprint, and not just the shorter
1337 keyID. If you feel it's important to sign the key of someone you've just
1338 met, also ask them to show you their government identification, and make
1339 sure the name on the ID matches the name on the public key.</p>

1367
1368 <p>Everyone uses GnuPG a little differently, but it's important to follow
1369 some basic practices to keep your email secure. Not following them, you
1370 risk the privacy of the people you communicate with, as well as your own,
1371 and damage the Web of Trust.</p>

1386 <h3>When should I encrypt? When should I sign?</h3>
1387
1388 <p>The more you can encrypt your messages, the better. If you only encrypt
1389 emails occasionally, each encrypted message could raise a red flag for
1390 surveillance systems. If all or most of your email is encrypted, people
1391 doing surveillance won't know where to start. That's not to say that only
1392 encrypting some of your email isn't helpful -- it's a great start and it
1393 makes bulk surveillance more difficult.</p>
1394
1395 <p>Unless you don't want to reveal your own identity (which requires other
1396 protective measures), there's no reason not to sign every message, whether or
1397 not you are encrypting. In addition to allowing those with GnuPG to verify
1398 that the message came from you, signing is a non-intrusive way to remind
1399 everyone that you use GnuPG and show support for secure communication. If you
1400 often send signed messages to people that aren't familiar with GnuPG, it's
1401 nice to also include a link to this guide in your standard email signature
1402 (the text kind, not the cryptographic kind).</p>

1419
1420 <p>GnuPG makes email safer, but it's still important to watch out for invalid
1421 keys, which might have fallen into the wrong hands. Email encrypted with
1422 invalid keys might be readable by surveillance programs.</p>
1423
1424 <p>In your email program, go back to the first encrypted email that Edward
1425 sent you. Because Edward encrypted it with your public key, it will have a
1426 green checkmark a at the top "OpenPGP" button.</p>
1427

1442 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>
1443

1455
1456 <p>If you lose your private key or someone else gets ahold

1458 important to revoke it immediately before someone else uses
1459 it to read your encrypted email or forge your signature. This

1462 After you're done revoking, make a new key and send an email to everyone
1463 with whom you usually use your key to make sure they know, including a copy
