97 Each person who chooses to resist mass surveillance makes it easier and less out of the ordinary for others to resist as well. People normalizing the use of strong cryptography helps whistle-blowers, dissidents, and activists and blend in better by providing cover traffic.</p>
98
99 <p>There's no objective method of what constitutes an interesting correspondance. As such, don't presume just because you find an email you sent to a friend innocous, your friend (or a third party, for that matter!) feels the same way. Show your friends respect by encrypting your correspondences with them.</p>
100
101 <p>Without our collective complacency, mass surveillance loses its effectiveness. This guide aims to help you facilitate Email Self-Defense workshops within your community, so that we may all stand a better chance of making the world a better, freer place!</p>

113 <h2><em>#0</em> Why GnuPG? </h2>
114
115 <p>NSA whistleblower Edward Snowden once famously <a href="http://www.theguardian.com/world/2013/jun/17/edward-snowden-nsa-files-whistleblower?CMP=twt_gu#block-51bf3588e4b082a2ed2f5fc5">wrote </a>, "Encryption works." When he chose to leak his information <a href="https://firstlook.org/theintercept/2014/10/28/smuggling-snowden-secrets/"> to film maker Laura Poitras</a>, he put his trust in the GNU Privacy Guard , and it didn't let him down. Although “encryption works,” even the most perfect software and algorithms still fail when the underlying system is not secure, or if the user doesn't understand how to properly make the software work for them.</p>
116
117 <p>Setting up a secure computer and understanding how it works is a daunting task, even for many advanced users. Simple mistakes lead to disaster, and many people who would benefit from using GnuPG don't simply because the process sounds too complex. GnuPG is a powerful and versatile program, and it's sad that more people don't use it.</P>
118
119 <p>If you already love GnuPG, do your part to help increase herd immunity to mass surveillance by helping your friends and neighbors master the challenges GnuPG poses. Help them keep their digital love letters private, and teach them the benefits of free software. Oftentimes, users over-calculate the complexity of setting up GnuPG, when all they really need is a ally to sit down with them and help them get started. Go be that friend!</P>

132 <h2><em>#1</em> Plan The Workshop</h2>
133 <p>When you hear friends bemoaning their lack of digital privacy, ask them if they're interested in attending a workshop to on email self-defense. Once you've got a handful of people interested, pick a date and start planning out the event. Tell participants to bring their computer, their ID (for signing each other's key) and a flash drive.</p>
134
135 <p>The success of each workshop requires understanding and catering to the unique background and needs of each group of participants. Workshops should stay small, so that participants receive more individualized instruction. If more than a handful of people want to participate, keep the participant:facilitator ratio low by recruiting more facilitators, or by facilitating multiple workshops. Ideally, facilitators should be known and trusted members of the participants' community. Small workshops among friends work great!</p>
136
137 <p>Many activists, journalists, whistleblowers, businessfolk, academics, and dissidents use the OpenPGP standard, so participants might unknowingly know of a few people who use it already. If possible, make a list of people and organizations that use OpenPGP which participants will likely recognize by searching for <a href="https://duckduckgo.com/?q=%22BEGIN+PGP+PUBLIC+KEY+BLOCK%22+%2B+%22free+software%22">"BEGIN PGP PUBLIC KEY BLOCK" + keyword</a>.</p>

Try and get all the participants to set up an Enigmail-compatible email client before the event. Direct them to their organizations IT department or help page if they run into errors. Estimate that the workshop to take at a minimum 30 minutes plus about five to 10 minutes for each participant. Plan extra time for glitches and questions.</p>

162 <p>Have the participants work through the Email Self-Defense guide a step at a time on their own computers. Make sure all participants complete each step before the group moves on to the next step. Talk about each step, but be sure not to overload the participants with minutia. Pitch the bulk of your instruction to the least tech-savvy participants. Consider holding a secondary workshop afterwards for the outliers in either direction.</p>

Recommend participants use the <a href="http://world.std.com/~reinhold/diceware.html"> diceware method </a>, and have dice and the wordlist available for them to use. Participants who choose to use diceware should keep their passphrase with them at all at all times until they memorize it. Stress the importance of creating and backing up revocation certificates, especially to participants who write down their diceware passphrases.</p>

208 <h2><em>#3</em> Sign Keys</h2>
209 <p>Emphasize the distinction between trusting a person subjectively, and seeing whose keys they've signed objectively. Without a proper understanding of trust, the beautiful transative trust properties of the web of trust are lost. Since trust is an internal and subjective thing, it's unnecessary for participants to share how much they trust another participant with anyone else.</p>
210
211 <p>Have the participants download each other's keys, read out their own fingerprints, and present their IDs to each other. Help participants navigate the interface to sign each other's keys, and encourage participants to assign each other trust levels if they already know each other.</p>

250 them to show you their ID (unless you trust them very highly) and their
251 public key fingerprint -- not just the shorter public key ID, which
252 could refer to another key as well. In Enigmail, answer honestly in the
