  82 &lt;p&gt; &lt;strong&gt; We want to translate this guide into more languages, and make a version for
  83 encryption on mobile devices. Please donate, and help people around the world take the

  99 alt="View &amp; share our infographic &rarr;" /&gt;&lt;/a&gt; Bulk surveillance violates
 100 our fundamental rights and makes free speech risky. This guide will teach you a basic
 101 surveillance self-defense skill: email encryption. Once you've finished, you'll be able to
 102 send and receive emails that are coded to make sure a surveillance agent or thief intercepting
 103 your email can't read it. All you need is a computer with an Internet connection, an email
 104 account, and about half an hour.&lt;/p&gt;
 105
 106 &lt;p&gt;Even if you have nothing to hide, using encryption helps protect the privacy of people
 107 you communicate with, and makes life difficult for bulk surveillance systems. If you do
 108 have something important to hide, you're in good company; these are the same tools that
 109 Edward Snowden used to share his famous secrets about the NSA.&lt;/p&gt;
 110
 111 &lt;p&gt;In addition to using encryption, standing up to surveillance requires fighting politically
 112 for a &lt;a href="http://gnu.org/philosophy/surveillance-vs-democracy.html"&gt;reduction in the
 113 amount of data collected on us&lt;/a&gt;, but the essential first step is to protect yourself
 114 and make surveillance of your communication as difficult as possible. Let's get started!&lt;/p&gt;

 127 &lt;p class="notes"&gt;This guide relies on software which is freely licensed; it's completely
 128 transparent and anyone can copy it or make their own version. This makes it safer from
 129 surveillance than proprietary software (like Windows). Learn more about free software at

 131
 132 &lt;p&gt;Most GNU/Linux operating systems come with GnuPG installed on them, so you don't have
 133 to download it. Before configuring GnuPG though, you'll need a desktop email program
 134 installed on your computer. Most GNU/Linux distributions have a free software version of
 135 the Thunderbird email program available to install. This guide will work with them, in
 136 addition to Thunderbird itself. Email programs are another way to access the same email
 137 accounts you can access in a browser (like Gmail), but provide extra features.&lt;/p&gt;

 245
 246 &lt;p&gt;To use the GnuPG system, you'll need a public key and a private key (known together as a
 247 keypair). Each is a long string of randomly generated numbers and letters that are unique to
 248 you. Your public and private keys are linked together by a special mathematical function.&lt;/p&gt;
 249
 250 &lt;p&gt;Your public key isn't like a physical key, because it's stored in the open in an online
 251 directory called a keyserver. People download it and use it, along with GnuPG, to encrypt
 252 emails they send to you. You can think of the keyserver as phonebook, where people who
 253 want to send you an encrypted email look up your public key.&lt;/p&gt;
 254
 255 &lt;p&gt;Your private key is more like a physical key, because you keep it to yourself (on your
 256 computer). You use GnuPG and your private key to decode encrypted emails other people send
 257 to you.&lt;/p&gt;

 577
 578 &lt;p&gt;Email encryption is a powerful technology, but it has a weakness; it requires a way to
 579 verify that a person's public key is actually theirs. Otherwise, there would be no way to
 580 stop an attacker from making an email address with your friend's name, creating keys to
 581 go with it and impersonating your friend. That's why the free software programmers that
 582 developed email encryption created keysigning and the Web of Trust.&lt;/p&gt;
 583
 584 &lt;p&gt;When you sign someone's key, you are publicly saying that you trust that it does belong
 585 to them and not an impostor. People who use your public key can see the number of signatures
 586 it has. Once you've used GnuPG for a long time, you may have hundreds of signatures. The
 587 Web of Trust is the constellation of all GnuPG users, connected to each other by chains of
 588 trust expressed through signatures, forming a giant network. The more signatures a key has,
 589 and the more signatures its signers' keys have, the more trustworthy that key is.&lt;/p&gt;
 590
 591 &lt;p&gt;People's public keys are usually identified by their key fingerprint, which is a string
 592 of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8 (for Edward's key). You can see the
 593 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>
 594 <span class="inserted"><ins><em>Enigmail</em></ins></span> &rarr; Key Management in your email program's menu, then right clicking on the
 595 key and choosing Key Properties. It's good practice to share your fingerprint wherever
 596 you share your email address, so that people can double-check that they have the correct
 597 public key when they download yours from a keyserver.&lt;/p&gt;
 598
 599 &lt;p class="notes"&gt;You may also see public keys referred to by their key ID, which is simply
 600 the last 8 digits of the fingerprint, like C09A61E8 for Edward. The key ID is visible
 601 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
 602 a useful shorthand but may not be unique to a given key), whereas the fingerprint actually
 603 identifies the key uniquely without the possibility of confusion. If you only have the key
 604 ID, you can still look up the key (as well as its fingerprint), like you did in Step 3,
 605 but if multiple options appear, you'll need the fingerprint of the person to whom are
 606 trying to communicate to verify which one to use.&lt;/p&gt;

 697 &lt;h3&gt;When should I encrypt?&lt;/h3&gt;
 698
 699 &lt;p&gt;The more you can encrypt your messages, the better. If you only encrypt emails
 700 occasionally, each encrypted message could raise a red flag for surveillance systems. If all
 701 or most of your email is encrypted, people doing surveillance won't know where to start.&lt;/p&gt;
 702
 703 &lt;p&gt;That's not to say that only encrypting some of your email isn't helpful -- it's a great
 704 start and it makes bulk surveillance more difficult.&lt;/p&gt;

 719 &lt;h3&gt;&lt;em&gt;Important:&lt;/em&gt; Be wary of invalid keys&lt;/h3&gt;
 720
 721 &lt;p&gt;GnuPG makes email safer, but it's still important to watch out for invalid keys, which
 722 might have fallen into the wrong hands. Email encrypted with invalid keys might be readable
 723 by surveillance programs.&lt;/p&gt;
 724
 725 &lt;p&gt;In your email program, go back to the second email that Edward sent you. Because Edward
 726 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
 727 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;
 728
 729 &lt;p&gt;&lt;b&gt;When using GnuPG, make a habit of glancing at that bar. The program will warn you
 730 there if you get an email encrypted with a key that can't be trusted.&lt;/b&gt;&lt;/p&gt;
 731
 732 &lt;/div&gt;&lt;!-- End .main --&gt;

 739 &lt;h3&gt;Copy your revocation certificate to somewhere safe&lt;/h3&gt;
 740
 741 &lt;p&gt;Remember when you created your keys and saved the revocation certificate that GnuPG
 742 made? It's time to copy that certificate onto the safest digital storage that you have --
 743 the ideal thing is a flash drive, disk, or hard drive stored in a safe place in your home.&lt;/p&gt;
 744
 745 &lt;p&gt;If your private key ever gets lost or stolen, you'll need this certificate file to let
 746 people know that you are no longer using that keypair.&lt;/p&gt;
 747
 748 &lt;/div&gt;&lt;!-- End .main --&gt;

 755 &lt;h3&gt;&lt;em&gt;Important:&lt;/em&gt; act swiftly if someone gets your private key&lt;/h3&gt;
 756
 757 &lt;p&gt;If you lose your private key or someone else gets ahold of it (say, by stealing or
 758 cracking your computer), it's important to revoke it immediately before someone else uses
 759 it to read your encrypted email. This guide doesn't cover how to revoke a key, but you
 760 can follow the &lt;a href="https://www.gnupg.org/gph/en/manual.html#AEN305"&gt;instructions on
 761 the GnuPG site&lt;/a&gt;. After you're done revoking, send an email to everyone with whom you
 762 usually use your key to make sure they know.&lt;/p&gt;
 763
 764 &lt;/div&gt;&lt;!-- End .main --&gt;

 771 &lt;h3&gt;Make your public key part of your online identity&lt;/h3&gt;
 772
 773 &lt;p&gt; First add your public key fingerprint to your email signature, then compose an email
 774 to at least five of your friends, telling them you just set up GnuPG and mentioning your
 775 public key fingerprint. Link to this guide and ask them to join you. Don't forget that
 776 there's also an awesome &lt;a href="infographic.html"&gt;infographic to share.&lt;/a&gt;&lt;/p&gt;
 777
 778 &lt;p class="notes"&gt;Start writing your public key fingerprint anywhere someone would see
 779 your email address: your social media profiles, blog, Website, or business card. (At the
 780 Free Software Foundation, we put ours on our &lt;a href="https://fsf.org/about/staff"&gt;staff
 781 page&lt;/a&gt;.) We need to get our culture to the point that we feel like something is missing
 782 when we see an email address without a public key fingerprint.&lt;/p&gt;
