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.

In addition to using encryption, standing up to surveillance requires fighting politically for a reduction in the amount of data collected on us, but the essential first step is to protect yourself and make surveillance of your communication as difficult as possible. This guide helps you do that. It is designed for beginners, but if you already know the basics of GnuPG or are an experienced free software user, you'll enjoy the advanced tips.

Open your email program and follow the wizard (step-by-step walkthrough) that sets it up with your email account. Look for the letters SSL, TLS, or STARTTLS to the right of the servers when you're setting up your account. If you don't see them, you will still be able to use encryption, but this means that the people running your email system are running behind the industry standard in protecting your security and privacy. We recommend that you send them a friendly email asking them to enable SSL, TLS, or STARTTLS for your email server. They will know what you're talking about, so it's worth making the request even if you aren't an expert on these security systems.

#2 Make your keys

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 and letters that are unique to you. Your public and private keys are linked together by a special mathematical function.

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.

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 descramble encrypted emails other people send to you. You should never share you private key with anyone, under any circumstances.

In addition to encryption and decryption, you can also use these keys to sign messages and check the authenticity of other people's signatures. This process helps stop impersonators. We'll discuss this more in the next section.

Step 2.a Make a keypair

The Enigmail Setup wizard may start automatically. If it doesn't, select Enigmail → Setup Wizard from your email program's menu. 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. Click Next with the default options selected, except in these instances:

On the screen titled "Encryption," select "Encrypt all of my messages by default, because privacy is critical to me."
On the screen titled "Signing," select "Don't sign my messages by default."
On the screen titled "Key Selection," select "I want to create a new key pair for signing and encrypting my email."
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!
On the screen titled "Create Key," pick a strong password! We recommend the Diceware method, which creates passwords which are both strong and memorable. To use the Diceware method, you will need dice and this list of words. Do not substitute computer dice for physical dice. Notice that each word on the word list corresponds to a unique five-digit number. Roll one die five times, or five dice once, then string the numbers on the dice dice together to create a five-digit number, and then look up the corresponding word.
Repeat this process until you have at least six words, separating each with a space and keeping them all lowercase. You'll end up with a password like "dog help people drive match ice." Don't rearrange or discard the words, because doing so makes the process much less secure.
Diceware passwords are hard to remember until you've typed them in a handful of times. Write down your password and keep it with you at all times until you've got it memorized. Then, destroy the piece of paper.
If you don't have dice, pick a password which is at least twelve characters long, and includes at least one lower case and upper case letter and at least one number or punctuation symbol. Never pick a password you've used elsewhere. Don't use any recognizable patterns, such as birthdays, telephone numbers, pets' names, song lyrics, quotes from books, and so on. Don't forget your password, or all of this work will be wasted!

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.

When the "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). You'll learn more about the revocation certificate in Section 5.

Command line key generation: If you prefer using the command line for a higher degree of control, you can follow the documentation from The GNU Privacy Handbook. Make sure you stick with "RSA and RSA" (the default), because it's newer and more secure than the algorithms the documentation recommendeds. Also make sure your key is at least 2048 bits, or 4096 if you really want to be secure.
Advanced key pairs: When GnuPG creates a new keypair, it compartmentalizes the encryption function from the signing function through subkeys. If you use subkeys carefully, you can keep your GnuPG identity much more secure and recover from a compromised key much more quickly. Alex Cabal and the Debian wiki provide good guides for setting up a secure subkey configuration.

#4 Learn the Web of Trust

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.

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.

When you sign someone's key, you are publicly saying that you've verified that it belongs to them and not an impostor. Signing keys and messages is the same type mathematical operation, but they carry very different implications. It's a good practice to generally sign your email, but if you casually sign people's keys, you may accidently end up vouching for the identity of an imposter!

People's public keys are usually identified by their key fingerprint, which is a string of digits like F357AA1A5B1FA42CFD9FE52A9FF2194CC09A61E8 (for Edward's key). You can see the fingerprint for your public key, and other public keys saved on your computer, by going to Enigmail → 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.

People who use your public key can see who has signed it. Once you've used GnuPG for a long time, you may have hundreds of signatures. The Web of Trust is a constellation of GnuPG users, connected to each other by chains of trust expressed through signatures. The more signatures of people you trust a key has, the more trustworthy that key is.

You may also see public keys referred to by their key ID, which is simply the last 8 digits of the fingerprint, like C09A61E8 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.

Important: check people's identification before signing their keys

Before signing a real person's key, always make sure it actually belongs to them, and that they are who they say they are. Ask them to show you their ID (unless you trust them very highly) and their public key fingerprint -- not just the shorter public key ID, which could refer to another key as well. In Enigmail, 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?".

Understanding and setting up email encryption sounds like a daunting task to many people. That's why helping your friends with GnuPG plays such an important role in helping spread encryption. Even if only one person shows up, that's still one more person using encryption who wasn't before. You have the power to help your friends keep their digital love letters private, and teach them about the importance of free software. If you use GnuPG to send and receive encrypted email, you're a perfect candidate for leading a workshop!

+ +

+ + +

#1 Get your friends or community interested

If you hear friends grumbling about their lack of privacy, ask them if they're interested in attending a workshop on Email Self-Defense. If your friends don't grumble about privacy, they may need some convincing. You might even hear the classic "if you've got nothing to hide, you've got nothing to fear" argument against using encryption.

Here are some arguments you can use to help explain why it's worth it to learn GnuPG. Mix and match whichever you think will make sense to your community:

+ +

+ + + + +

Strength in numbers

Each person who chooses to resist mass surveillance with encryption makes it easier for others to resist as well. People normalizing the use of strong encryption has multiple powerful effects: it means those that truly need privacy, like potential whistle-blowers and activists, are more likely to learn about encryption. More people using encryption for more things also makes it harder for surveillance systems to single out those that can't afford to be found, and shows solidarity with those people.

+ +

People you respect may already be using encryption

Many journalists, whistleblowers, activists, and researchers use GnuPG, so your friends might unknowingly have heard of a few people who use it already. You can search for "BEGIN PUBLIC KEY BLOCK" + keyword to help make a list of people and organizations who use GnuPG which your community will likely recognize.

+ +

Respect your friends' privacy

There's no objective way to judge what constitutes a privacy-sensitive correspondence. As such, it's better not to presume that just because you find an email you sent to a friend innocuous, your friend (or a surveillance agent, for that matter!) feels the same way. Show your friends respect by encrypting your correspondences with them.

+ + +

Privacy technology is normal in the physical world

In the physical realm, we take window blinds, envelopes, and closed doors for granted as ways of protecting our privacy. Why should the digital realm be any different?

+ + +

+ +

+ + +

+ +

#2 Plan The Workshop

Once you've got at least one interested friend, pick a date and start planning out the workshop. Tell participants to bring their computer and ID (for signing each other's keys). Also tell the participants to bring dice (for making passwords), but also bring as many as you can, in case they don't. Make sure the location you select has an easily accessible Internet connection, and make backup plans in case the connection stops working on the day of the workshop. Libraries, coffee shops, and community centers make great locations. Try to get all the participants to set up an Enigmail-compatible email client before the event. Direct them to their email provider's IT department or help page if they run into errors.

Estimate that the workshop will take forty minutes plus ten minutes for each participant, at a minimum. Plan extra time for questions and technical glitches.

The success of the workshop requires understanding and catering to the unique backgrounds and needs of each group of participants. Workshops should stay small, so that each participant receives more individualized instruction. If more than a handful of people want to participate, keep the facilitator to participant ratio low by recruiting more facilitators, or by facilitating multiple workshops. Small workshops among friends work great!

+ + +

+ +

+ + +

+ +

#3 Follow the guide as a group

Work through the Email Self-Defense guide a step at time as a group. Talk about the steps in detail, but make sure not to overload the participants with minutia. Pitch the bulk of your instructions to the least tech-savvy participants. Make sure all the participants complete each step before the group moves on to the next one. Consider facilitating secondary workshops afterwards for people that had trouble grasping the concepts, or those that grasped them quickly and want to learn more.

Even powerful surveillance systems can't break private keys when they're protected by lengthy Diceware passphrases. Make sure participants use the Diceware method, if dice are available. Stress the importance of eventually destroying the piece of paper the Diceware password is written on, and make sure all the participants back up their revocation certificates.

In Section 2 of the guide, make sure the participants upload their keys to the same keyserver so that they can immediately download each other's keys later (sometimes there is a delay in synchronization between keyservers). During Section 3, give the participants the option to send encrypted messages to each other instead of or as well as Edward. Similarly, in Section 4, encourage the participants to sign each other's keys.

Remind participants that encryption works only when it's explicitly used; they won't be able to send an encrypted email to someone who hasn't already set up encryption. Also remind participants to double-check the encryption icon before hitting send, and that subjects and timestamps are never encrypted. See the guide's Security Tips subsection for more information.

Advocate for free software, because without it, we can't meaningfully resist invasions of our digital privacy and autonomy. Explain the dangers of running a proprietary system, and why GnuPG can't begin to mitigate them.

#5 Share additional resources

GnuPG's advanced options are far too complex to teach in a single workshop. If participants want to know more, point out the advanced subsections in the guide and consider organizing another workshop. You can also share GnuPG's and Enigmail's official documentation and mailing lists. Many GNU/Linux distribution's Web sites also contain a page explaining some of GnuPG's advanced features.

#6 Follow up

Encourage the participants to continue to gain GnuPG experience by emailing each other, and considering offering to correspond with them in encrypted form. If you don't hear from them for a couple of weeks after the event, reach out and see if they would like additional assistance.

If you have any suggestions for improving this workshop guide, please let us know at campaigns@fsf.org.
