69 <p>The goal of this guide is to make it easy to set up email encryption on your computer. 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>
70 <!--<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>-->
71 <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>
f584fc69 72 <p>This guide relies on software which is freely licensed; it's completely transparent and anyone can copy it or make their own version. This makes it safer from surveillance than proprietary software (like Windows). Learn more about free software at <a href="https://u.fsf.org/ys">fsf.org</a>.</p>

eacb2880
ZR
266 <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 friends name, creating keys to go with it and impersonating your friend.</p>
267
268 <p>That's why the programmers that developed email encryption created keysigning and the Web of Trust. When you sign someone's key, you are publicly saying that you trust that it does belong to them and not an impostor.</p>
269
270<p>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 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 it's signers' keys have, the more trustworthy that key is.</p>

326 <h3>When should I encrypt?</h3>
327
328 <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>
329
eacb2880 330<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. And even people that encrypt as much as they can are still limited to those of their contacts that have public keys.</p>

339 <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>

356 <p>If you lose your private key or someone else gets ahold of it (say, by stealing or cracking your computer), it's important to revoke it immediately before someone else uses it to steal your identity. This guide doesn't cover how to revoke a key, but it only takes a minute. We recommend you Google it or seek help from a skilled friend. After you're done revoking, send an email to everyone with whom you usually use your key to make sure they know.</p>
