 109 alt="View &amp; share our infographic &rarr;" /&gt;&lt;/a&gt; Bulk surveillance violates
 110 our fundamental rights and makes free speech risky. This guide will teach you a basic
 111 surveillance self-defense skill: email encryption. Once you've finished, you'll be able to
 112 send and receive emails that are coded to make sure a surveillance agent or thief intercepting
 113 your email can't read it. All you need is a computer with an Internet connection, an email
 114 account, and about half an hour.&lt;/p&gt;
 115
 116 &lt;p&gt;Even if you have nothing to hide, using encryption helps protect the privacy of people
 117 you communicate with, and makes life difficult for bulk surveillance systems. If you do
 118 have something important to hide, you're in good company; these are the same tools that
 119 Edward Snowden used to share his famous secrets about the NSA.&lt;/p&gt;
 120
 121 &lt;p&gt;In addition to using encryption, standing up to surveillance requires fighting politically
 122 for a &lt;a href="http://gnu.org/philosophy/surveillance-vs-democracy.html"&gt;reduction in the
 123 amount of data collected on us&lt;/a&gt;, but the essential first step is to protect yourself
 124 and make surveillance of your communication as difficult as possible. Let's get started!&lt;/p&gt;

 137 &lt;p class="notes"&gt;This guide relies on software which is freely licensed; it's
 138 completely transparent and anyone can copy it or make their own version. This makes
 139 it safer from surveillance than proprietary software (like Windows). To defend your
 140 freedom as well as protect yourself from surveillance, we recommend you switch to a
 141 free software operating system like GNU/Linux. Learn more about free software at &lt;a
 142 href="https://u.fsf.org/ys"&gt;fsf.org&lt;/a&gt;.&lt;/p&gt;
 143
 144 &lt;p&gt;To get started, you'll need a desktop email program installed on your computer. This guide
 145 works with free software versions of the Thunderbird email program, and with Thunderbird
 146 itself. Email programs are another way to access the same email accounts you can access
 147 in a browser (like Gmail), but provide extra features.&lt;/p&gt;

 269
 270 &lt;p&gt;To use the GnuPG system, you'll need a public key and a private key (known together as a
 271 keypair). Each is a long string of randomly generated numbers and letters that are unique to
 272 you. Your public and private keys are linked together by a special mathematical function.&lt;/p&gt;
 273
 274 &lt;p&gt;Your public key isn't like a physical key, because it's stored in the open in an online
 275 directory called a keyserver. People download it and use it, along with GnuPG, to encrypt
 276 emails they send to you. You can think of the keyserver as phonebook, where people who
 277 want to send you an encrypted email look up your public key.&lt;/p&gt;
 278
 279 &lt;p&gt;Your private key is more like a physical key, because you keep it to yourself (on your
 280 computer). You use GnuPG and your private key to decode encrypted emails other people send
 281 to you.&lt;/p&gt;

 595
 596 &lt;p&gt;Email encryption is a powerful technology, but it has a weakness; it requires a way to
 597 verify that a person's public key is actually theirs. Otherwise, there would be no way to
 598 stop an attacker from making an email address with your friend's name, creating keys to
 599 go with it and impersonating your friend. That's why the free software programmers that
 600 developed email encryption created keysigning and the Web of Trust.&lt;/p&gt;
 601
 602 &lt;p&gt;When you sign someone's key, you are publicly saying that you trust that it does belong
 603 to them and not an impostor. People who use your public key can see the number of signatures
 604 it has. Once you've used GnuPG for a long time, you may have hundreds of signatures. The
 605 Web of Trust is the constellation of all GnuPG users, connected to each other by chains of
 606 trust expressed through signatures, forming a giant network. The more signatures a key has,
 607 and the more signatures its signers' keys have, the more trustworthy that key is.&lt;/p&gt;
 608
 609 &lt;p&gt;People's public keys are usually identified by their key fingerprint, which is a string
 610 of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8 (for Edward's key). You can see the
 611 fingerprint for your public key, and other public keys saved on your computer, by going to <span class="removed"><del><strong>OpenPGP</strong></del></span>
 612 <span class="inserted"><ins><em>Enigmail</em></ins></span> &rarr; Key Management in your email program's menu, then right clicking on the
 613 key and choosing Key Properties. It's good practice to share your fingerprint wherever
 614 you share your email address, so that people can double-check that they have the correct
 615 public key when they download yours from a keyserver.&lt;/p&gt;
 616
 617 &lt;p class="notes"&gt;You may also see public keys referred to by their key ID, which is simply
 618 the last 8 digits of the fingerprint, like C09A61E8 for Edward. The key ID is visible
 619 directly from the Key Management <span class="removed"><del><strong>Window.</strong></del></span> <span class="inserted"><ins><em>window.</em></ins></span> This key ID is like a person's first name (it is
 620 a useful shorthand but may not be unique to a given key), whereas the fingerprint actually
 621 identifies the key uniquely without the possibility of confusion. If you only have the key
 622 ID, you can still look up the key (as well as its fingerprint), like you did in Step 3,
 623 but if multiple options appear, you'll need the fingerprint of the person to whom are
 624 trying to communicate to verify which one to use.&lt;/p&gt;

 682 very highly) and their public key fingerprint -- not just the shorter public key ID, which

 699 &lt;p&gt;Everyone uses GnuPG a little differently, but it's important to follow some basic
 700 practices to keep your email secure. Not following them, you risk the privacy of the people
 701 you communicate with, as well as your own, and damage the Web of Trust.&lt;/p&gt;

 715 &lt;h3&gt;When should I encrypt?&lt;/h3&gt;
 716
 717 &lt;p&gt;The more you can encrypt your messages, the better. If you only encrypt emails
 718 occasionally, each encrypted message could raise a red flag for surveillance systems. If all
 719 or most of your email is encrypted, people doing surveillance won't know where to start.&lt;/p&gt;
 720
 721 &lt;p&gt;That's not to say that only encrypting some of your email isn't helpful -- it's a great
 722 start and it makes bulk surveillance more difficult.&lt;/p&gt;
 723
 724 &lt;/div&gt;&lt;!-- End .main --&gt;

 737 &lt;h3&gt;&lt;em&gt;Important:&lt;/em&gt; Be wary of invalid keys&lt;/h3&gt;
 738
 739 &lt;p&gt;GnuPG makes email safer, but it's still important to watch out for invalid keys, which
 740 might have fallen into the wrong hands. Email encrypted with invalid keys might be readable
 741 by surveillance programs.&lt;/p&gt;
 742
 743 &lt;p&gt;In your email program, go back to the second email that Edward sent you. Because Edward
 744 encrypted it with your public key, it will have a message from <span class="removed"><del><strong>OpenPGP</strong></del></span> <span class="inserted"><ins><em>Enigmail</em></ins></span> at the top, which
 745 most likely says <span class="removed"><del><strong>"OpenPGP:</strong></del></span> <span class="inserted"><ins><em>"Enigmail:</em></ins></span> Part of this message encrypted."&lt;/p&gt;
 746
 747 &lt;p&gt;&lt;b&gt;When using GnuPG, make a habit of glancing at that bar. The program will warn you
 748 there if you get an email encrypted with a key that can't be trusted.&lt;/b&gt;&lt;/p&gt;
 749
 750 &lt;/div&gt;&lt;!-- End .main --&gt;

 757 &lt;h3&gt;Copy your revocation certificate to somewhere safe&lt;/h3&gt;
 758
 759 &lt;p&gt;Remember when you created your keys and saved the revocation certificate that GnuPG
 760 made? It's time to copy that certificate onto the safest digital storage that you have --
 761 the ideal thing is a flash drive, disk, or hard drive stored in a safe place in your home.&lt;/p&gt;
 762
 763 &lt;p&gt;If your private key ever gets lost or stolen, you'll need this certificate file to let
 764 people know that you are no longer using that keypair.&lt;/p&gt;
 765
 766 &lt;/div&gt;&lt;!-- End .main --&gt;

 773 &lt;h3&gt;&lt;em&gt;Important:&lt;/em&gt; act swiftly if someone gets your private key&lt;/h3&gt;
 774
 775 &lt;p&gt;If you lose your private key or someone else gets ahold of it (say, by stealing or
 776 cracking your computer), it's important to revoke it immediately before someone else uses
 777 it to read your encrypted email. This guide doesn't cover how to revoke a key, but you
 778 can follow the &lt;a href="https://www.gnupg.org/gph/en/manual.html#AEN305"&gt;instructions on
 779 the GnuPG site&lt;/a&gt;. After you're done revoking, send an email to everyone with whom you
 780 usually use your key to make sure they know.&lt;/p&gt;
 781
 782 &lt;/div&gt;&lt;!-- End .main --&gt;

 789 &lt;h3&gt;Make your public key part of your online identity&lt;/h3&gt;
 790
 791 &lt;p&gt; First add your public key fingerprint to your email signature, then compose an email
 792 to at least five of your friends, telling them you just set up GnuPG and mentioning your
 793 public key fingerprint. Link to this guide and ask them to join you. Don't forget that
 794 there's also an awesome &lt;a href="infographic.html"&gt;infographic to share.&lt;/a&gt;&lt;/p&gt;
 795
 796 &lt;p class="notes"&gt;Start writing your public key fingerprint anywhere someone would see
 797 your email address: your social media profiles, blog, Website, or business card. (At the
 798 Free Software Foundation, we put ours on our &lt;a href="https://fsf.org/about/staff"&gt;staff
 799 page&lt;/a&gt;.) We need to get our culture to the point that we feel like something is missing
 800 when we see an email address without a public key fingerprint.&lt;/p&gt;
