+ Bulk surveillance violates our fundamental rights and makes free speech risky. This guide will teach you a basic surveillance self-defense skill: email encryption. Once you've finished, you'll be able to send and receive emails that are coded to make sure that a surveillance agent or thief can't intercept your email and read it.</p>
+
+<p>Even if you have nothing to hide, using encryption helps protect the privacy of people you communicate with, and makes life difficult for bulk surveillance systems. If you do have something important to hide, you're in good company; these are the same tools that Edward Snowden used to share his famous secrets about the NSA.</p>
+
<!--<p>You'll also be able to sign emails to show reliably that they are from you. Though the need for signing may be less obvious, you'll actually do it more often.</p>-->
- <p>All you need is a computer with an Internet connection, an email account and about half an hour. You can use your existing email account for this without affecting it.</p>

<div class="troubleshooting">
<div class="section-intro">
<h2><em>#2</em> Make your keys</h2>
<p>To use the GnuPG system, you'll need a public key and a private key (known together as a keypair). Each is a long string of randomly generated numbers that are unique to you. Your public and private keys are linked together by a special mathematical function.</p>
+
+<p>Your public key isn't like a physical key, because it's stored in the open in an online directory called a keyserver. People download it and use it, along with GnuPG, to encrypt emails they send to you. You can think of the keyserver as phonebook, where people who want to send you an encrypted email look up your public key.</p>
+
+<p>Your private key is more like a physical key, because you keep it to yourself (on your computer). You use GnuPG and your private key to decode encrypted emails other people send to you.</p>

<p>Use the default options until you reach the screen titled "Create Key".</p>

<div class="section-intro">
<h2><em>#4</em> Learn the Web of Trust</h2>
- <p>Email encryption is a powerful technology, but it has a weakness; it requires a way to verify that a person's keypair is actually theirs. Otherwise, there would be no way to stop an attacker from making an email address with your friends name, creating a keypair to go with it and impersonating your friend. They would then be able to impersonate your friend by signing messages with the private key they'd created, and decrypt messages intended for your friend with the public key.</p>
- <p>That's why the programmers that developed email encryption created keysigning and the Web of Trust. Keysigning allows a person to publicly state that they trust that a public key belongs to a specific person. To sign someone's public key, you need to use your private key, so the world will know that it was you.</p>
+ <p>Email encryption is a powerful technology, but it has a weakness; it requires a way to verify that a person's public key is actually theirs. Otherwise, there would be no way to stop an attacker from making an email address with your friend's name, creating keys to go with it and impersonating your friend. That's why the free software programmers that developed email encryption created keysigning and the Web of Trust.</p>
+
+<p>When you sign someone's key, you are publicly saying that you trust that it does belong to them and not an impostor. People who use your public key can see the number of signatures it has. Once you've used GnuPG for a long time, you may have hundreds of signatures. The Web of Trust is the constellation of all GnuPG users, connected to each other by chains of trust expressed through signatures, into a giant Web. The more signatures a key has, and the more signatures its signers' keys have, the more trustworthy that key is.</p>
+
+<p>People's public keys are usually identified by their key ID, which is a short string of 8 digits like 92AB3FF7 (for Adele's key). You can see your key ID on the right in OpenPGP → Key Management in your email program's menu.</p>
+<p>It's good practice to share your key ID, so that so that people can double-check that they have the correct public key when they download yours from a keyserver. You may also see public keys referred to by their key fingerprint, which is a longer string of digits, like DD878C06E8C2BEDDD4A440D3E573346992AB3FF7. The key ID is just the last 8 digits of the fingerprint.</p>

<p>In your email program's menu, go to OpenPGP → Key Management → Keyserver → Upload Public Keys and hit OK.</p>
- <p class="highlight">You've just effectively said "I trust that Adele's public key actually belongs to Adele." This doesn't mean much because Adele isn't a real person. Before signing a real person's key, always make sure it actually belongs to them, and answer honestly in the window that pops up and asks "How carefully have you verified that the key you are about to sign actually belongs to the person(s) named above?".</p>
- <p class="highlight">It's important to take keysigning seriously because it will affect people beyond just you and the person who's key you are signing. If someone doubts that a key actually belongs to the person that is says it does, they can go on a keyserver and see the number of signatures that it has. The more it has, the more they are likely to trust it.</p>
- <p class="highlight">The Web of Trust takes this concept to the next level. It is a network of key signatures that is saved in keyservers on the Internet. It builds chains of trust between individuals that do not know each other by passing through others, a bit like the famous <a href="http://en.wikipedia.org/wiki/Six_degrees_of_separation">"six degrees of separation" game</a>. You don't need to understand it in detail to use email encryption, but it will become a powerful tool if you become an advanced user.</p>

- <h3><em>Step 5a</em> When should I encrypt? When should I sign?</h3>
- <p>Everyone uses GnuPG a little differently. Encryption is most important for messages involving finances, personal information, politically sensitive conversations and anything else that you wouldn't want to fall into the wrong hands. Signing is best for when you think there might be concern about your identity, or as a way of demonstrating that you know how to use GnuPG and will be able to decrypt emails. If you're already encrypting, there's no reason not to sign as well, to give the recipient added assurance that the message is from you.</p>
- <p>If you're using your email program (or wherever you have GnuPG set up) often, we recommend that you sign all outgoing messages because it turns you into an ambassador for GnuPG. Anyone can read a signed email, so it doesn't matter if the recipient doesn't yet know how to use email encryption. The more you encrypt the better, but you won't be able to do so unless the recipient has a public key. However, if you've set it up for an email program on your computer, but you primarily use email through your phone, then you'll only want to fire up the email program and use GnuPG for special occasions. If this describes you, we recommend you use </p>
+ <h3>When should I encrypt?</h3>
+
+ <p>The more you can encrypt your messages, the better. This is because, if you only encrypt emails occasionally, each encrypted message could raise a red flag for surveillance systems. If all or most of your email is encrypted, people doing surveillance won't know where to start.</p>
+
+<p>That's not to say that only encrypting some of your email isn't helpful -- it's a great start and it makes bulk surveillance more difficult.</p>

+ <p>GnuPG makes email safer, but it's still important to watch out for invalid keys, which might have fallen into the wrong hands. Email encrypted with invalid keys might be readable by surveillance programs.</p>
+ <p>In your email program, go back to the second email that Adele sent you. Because it was encrypted with her key, it will have a message from OpenPGP at the top, which most likely says "OpenPGP: Part of this message encrypted."</p>

+ <h3>Copy your revocation certificate to somewhere safe</h3>
+ <p>Remember when you created your keys and saved the revocation cerfiticate that GnuPG made? It's time to copy that cerfiticate onto the safest digital storage that you have -- the ideal thing is a flash drive, disk or hard drive stored in a safe place in your home.</p>

<h3>Go to a keysigning party</h3>
- <p>Keysigning parties are social events designed to build the Web of Trust. Participants match each others' photo IDs and Key IDs, and then get out their laptops and sign each other's public keys. They're a great way to meet likeminded people and learn about new privacy tools, as well as build up people's trust in your key. Look for keysigning at tech events, hackerspaces and nerdy parties.</p>
