<p>In addition to using encryption, standing up to surveillance requires fighting politically for a <a href="http://gnu.org/philosophy/surveillance-vs-democracy.html">reduction in the amount of data collected on us</a>, but the essential first step is to protect yourself and make surveillance of your communication as difficult as possible. Let's get started!</p>

<h3><em>Step 2.a</em> Make a keypair</h3>
<p>In your email program's menu, select OpenPGP → Setup Wizard. You don't need to read the text in the window that pops up unless you'd like to, but it's good to read the text on the later screens of the wizard.</p>
- <p>On the second screen, titled "Signing," select "No, I want to create per-recipient rules for emails that need to be signed."</p>
+ <p>On the second screen, titled "Encryption," select "Encrypt all of my messages by default, because privacy is critical to me."</p>
+ <p>On the third screen, titled "Signing," select "Don't sign my messages by default."</p>
<p>Use the default options until you reach the screen titled "Create Key".</p>
<p>On the screen titled "Create Key," pick a strong password! Your password should be at least 12 characters and include at least one lower case and upper case letter and at least one number or punctuation symbol. Don't forget the password, or all this work will be wasted!</p>
<p class="notes">The program will take a little while to finish the next step, the "Key Creation" screen. While you wait, do something else with your computer, like watching a movie or browsing the Web. The more you use the computer at this point, the faster the key creation will go.</p>
- <p>When the
OpenPGP Confirm screen pops up, select Generate Certificate and choose to save it in a safe place on your computer (we recommend making a folder called "Revocation Certificate" in your home folder and keeping it there). You'll learn more about the revocation certificate in <a href="#section5">Section 5</a>. The setup wizard will ask you to move it onto an external device, but that isn't necessary at this moment.</p>

"Key Generation Completed" screen pops up, select Generate Certificate and choose to save it in a safe place on your computer (we recommend making a folder called "Revocation Certificate" in your home folder and keeping it there).

<h3><em>Step 3.b</em> Send a test encrypted email</h3>
<p>Write a new email in your email program, addressed to edward-en@fsf.org. Make the subject "Encryption test" or something similar and write something in the body. Don't send it yet.</p>
- <p>Click the icon of the key in the bottom right of the composition window (it should turn yellow). This tells Enigmail to encrypt the email with the key you downloaded in the last step.</p>
+ <p>Click the icon of the key in the bottom right of the composition window (it should turn yellow). This tells Enigmail to encrypt the email.</p>
<p class="notes">Next to the key, you'll notice an icon of a pencil. Clicking this tells Enigmail to add a special, unique signature to your message, generated using your private key. This is a separate feature from encryption, and you don't have to use it for this guide.</p>
<p>Click Send. Enigmail will pop up a window that says "Recipients not valid, not trusted or not found."</p>
- <p>To encrypt an email to Edward, you need his public key, so now you'll have Enigmail download it from a keyserver. Click Download Missing Keys and use the default in the pop-up that asks you to choose a keyserver. Once it finds keys, check the first one (Key ID starting with 9), then select ok. Select ok in the next pop-up.</p>

<p>Now you are back at the "Recipients not valid, not trusted or not found" screen. Select Edward's key from the list and click Ok. If the message doesn't send automatically, you can hit send now.</p>
<!-- ~~~~~~~~~ Troubleshooting ~~~~~~~~~ -->
<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, forming a giant network. 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 fingerprint, which is a string of digits like DD878C06E8C2BEDDD4A440D3E573346992AB3FF7 (for Edward's key). You can see the fingerprint for your public key, and other public keys saved on your computer, by going to OpenPGP → Key Management in your email program's menu, then right clicking on the key and choosing Key Properties. It's good practice to share your fingerprint wherever you share your email address, so that people can double-check that they have the correct public key when they download yours from a keyserver.</p>

-<p class="notes">You may also see public keys referred to by their key ID, which is simply the last 8 digits of the fingerprint, like 92AB3FF7 for Edward. The key ID is visible directly from the Key Management Window. This key ID is like a person's first name (it is a useful shorthand but may not be unique to a given key), whereas the fingerprint actually identifies the key uniquely without the possibility of confusion. If you only have the key ID, you can still look up the key (as well as its fingerprint), like you did in Step 3, but if multiple options appear, you'll need the fingerprint of the person to whom are trying to communicate to verify which one to use.</p>
