#1 Get the pieces

+ +

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 fsf.org.

+ +

Most GNU/Linux operating systems come with GnuPG installed on them, +so you don't have to download it. Before configuring GnuPG though, you'll +need the IceDove desktop email program installed on your computer. Most +GNU/Linux distributions have IceDove installed already, though it may be +under the alternate name "Thunderbird." Email programs are another way to +access the same email accounts you can access in a browser (like Gmail), +but provide extra features.

+ +

If you already have an email program, you can skip to Step 1.b.

+ +
+ + +
+ +
+ +

Step 1.a Set up your email program with your email account

+ +

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.

+ + +
+ +

Troubleshooting

+ +
+
The wizard doesn't launch
+
You can launch the wizard yourself, but the menu option for doing so is +named differently in each email program. The button to launch it will be in +the program's main menu, under "New" or something similar, titled something +like "Add account" or "New/Existing email account."
+ +
The wizard can't find my account or isn't downloading my mail
+
Before searching the Web, we recommend you start by asking other people +who use your email system, to figure out the correct settings.
+ + + +
+ +
+
+
+ + +
+ +
+ +

Step 1.b Install the Enigmail plugin for your email program

+ +

In your email program's menu, select Add-ons (it may be in the Tools +section). Make sure Extensions is selected on the left. Do you see Enigmail? If +so, skip this step.

+ +

If not, search "Enigmail" with the search bar in the upper right. You +can take it from here. Restart your email program when you're done.

+ + +
+ +

Troubleshooting

+ +
+
I can't find the menu.
+
In many new email programs, the main menu is represented by an image of +three stacked horizontal bars.
+ +
My email looks weird
+
Enigmail doesn't tend to play nice with HTML, which is used to format +emails, so it may disable your HTML formatting automatically. To send an +HTML-formatted email without encryption or a signature, hold down the Shift +key when you select compose. You can then write an email as if Enigmail +wasn't there.
+ + + +
+ +
+
+
+
+ + +
+ + +
+ +

#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 a phonebook; people who want to send you encrypted email can +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 together 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. 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, which are listed +in the order they appear:

+ +
    +
  • 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! You can +do it manually, or you can use the Diceware method. Doing it manually +is faster but not as secure. Using Diceware takes longer and requires +dice, but creates a password that is much harder for attackers figure +out. To use it, read the section "Make a secure passphrase with Diceware" in this +article by Micah Lee.
  • +
+ +

If you'd like to pick a password manually, come up with something +you can remember 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.

+ +

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). This step is essential for your +email self-defense, as you'll learn more about in Section +5.

+ + +
+ +

Troubleshooting

+ +
+
I can't find the Enigmail menu.
+
In many new email programs, the main menu is represented by an image +of three stacked horizontal bars. Enigmail may be inside a section called +Tools.
+ +
The wizard says that it cannot find GnuPG.
+
Open whatever program you usually use for installing software, and search +for GnuPG, then install it. Then restart the Enigmail setup wizard by going +to Enigmail → Setup Wizard.
+ +
My email looks weird
+
Enigmail doesn't tend to play nice with HTML, which is used to format +emails, so it may disable your HTML formatting automatically. To send an +HTML-formatted email without encryption or a signature, hold down the Shift +key when you select compose. You can then write an email as if Enigmail +wasn't there.
+ +

+ + +
+ +

Advanced

+ +
+
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 +recommends. Also make sure your key is at least 2048 bits, or 4096 if you +want to be extra 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.
+
+ +
+
+
+ + +
+
+ +

Step 2.b Upload your public key to a keyserver

+ +

In your email program's menu, select Enigmail → Key Management.

+ +

Right click on your key and select Upload Public Keys to Keyserver. Use +the default keyserver in the popup.

+ +

Now someone who wants to send you an encrypted message can +download your public key from the Internet. There are multiple keyservers +that you can select from the menu when you upload, but they are all copies +of each other, so it doesn't matter which one you use. However, it sometimes +takes a few hours for them to match each other when a new key is uploaded.

+ + +
+ +

Troubleshooting

+ +
+
The progress bar never finishes
+
Close the upload popup, make sure you are connected to the Internet, +and try again. If that doesn't work, try again, selecting a different +keyserver.
+ +
My key doesn't appear in the list
+
Try checking "Display All Keys by Default."

Uploading a key from the command line
+
You can also upload your keys to a keyserver through the command line. The sks Web site +maintains a list of highly interconnected keyservers. You can also directly export +your key as a file on your computer.
+
+ +
+
+
+ + +
+
+ +

GnuPG, OpenPGP, what?

+ +

In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP +are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the +encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG) +is the program that implements the standard. Enigmail is a plug-in program +for your email program that provides an interface for GnuPG.

+ +
+
+
+ + +
+ + +
+ +

#3 Try it out!

+ +

Now you'll try a test correspondence with a computer program named Edward, +who knows how to use encryption. Except where noted, these are the same +steps you'd follow when corresponding with a real, live person.

+ + +
+ + +
+ +
+ +

Step 3.a Send Edward your public key

+ +

This is a special step that you won't have to do when corresponding +with real people. In your email program's menu, go to Enigmail → Key +Management. You should see your key in the list that pops up. Right click +on your key and select Send Public Keys by Email. This will create a new +draft message, as if you had just hit the Write button.

+ +

Address the message to edward-en@fsf.org. Put at least one word +(whatever you want) in the subject and body of the email. Don't send yet.

+ +

The lock icon in the top left should be yellow, meaning encryption is +turned on. We want this first special message to be unencrypted, so +click the icon once to turn it off. The lock should become grey, with a +blue dot on it (to alert you that the setting has been changed from the +default). Once encryption is off, hit Send.

+ +

It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide. Once he's responded, +head to the next step. From here on, you'll be doing just the same thing as +when corresponding with a real person.

+ +

When you open Edward's reply, GnuPG may prompt you for your password +before using your private key to decrypt it.

+ +
+
+ + +
+
+ +

Step 3.b Send a test encrypted email

+ +

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.

+ +

The lock icon in the top left of the window should be yellow, meaning +encryption is on. This will be your default from now on.

+ +

Next to the lock, you'll notice an icon of a pencil. We'll +get to this in a moment.

+ +

Click Send. Enigmail will pop up a window that says "Recipients not valid, +not trusted or not found."

+ +

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 C), then select ok. Select +ok in the next pop-up.

+ +

Now you are back at the "Recipients not valid, not trusted or not found" +screen. Check the box in front of Edward's key and click Send.

+ +

Since you encrypted this email with Edward's public key, +Edward's private key is required to decrypt it. Edward is the only one with +his private key, so no one except him can decrypt it.

+ + +
+ +

Troubleshooting

+ +
+
Enigmail can't find Edward's key
+
Close the pop-ups that have appeared since you clicked Send. Make sure +you are connected to the Internet and try again. If that doesn't work, repeat +the process, choosing a different keyserver when it asks you to pick one.
+ +
Unscrambled messages in the Sent folder
+
Even though you can't decrypt messages encrypted to someone else's key, +your email program will automatically save a copy encrypted to your public key, +which you'll be able to view from the Sent folder like a normal email. This +is normal, and it doesn't mean that your email was not sent encrypted.
+ +

+

+ + + +
+ +
+ + +
+ +

Advanced

+ +
+
Encrypt messages from the command line
+
You can also encrypt and decrypt messages and files from the command line, +if that's your preference. The option --armor makes the encrypted output +appear in the regular character set.
+
+ +
+
+
+ + +
+
+ +

Important: Security tips

-
+

Even if you encrypt your email, the subject line is not encrypted, so +don't put private information there. The sending and receiving addresses +aren't encrypted either, so a surveillance system can still figure out who +you're communicating with. Also, surveillance agents will know that you're +using GnuPG, even if they can't figure out what you're saying. When you +send attachments, Enigmail will give you the choice to encrypt them or not, +independent of the actual email.

+ + + +
+
+ +

Step 3.c Receive a response

+ +

When Edward receives your email, he will use his private key to decrypt +it, then use your public key (which you sent him in Step +3.A) to encrypt his reply to you.

+ +

It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide.

+ +

When you receive Edward's email and open it, Enigmail will automatically +detect that it is encrypted with your public key, and then it will use your +private key to decrypt it.

+ +

Notice the bar that Enigmail shows you above the message, with information +about the status of Edward's key.

+ +
+
+ + +
+
+ +

Step 3.d Send a test signed email

+ +

GnuPG includes a way for you to sign messages and files, verifying that +they came from you and that they weren't tampered with along the way. These +signatures are stronger than their pen-and-paper cousins -- they're impossible +to forge, because they're impossible to create without your private key +(another reason to keep your private key safe).

+ +

You can sign messages to anyone, so it's a great way to make people +aware that you use GnuPG and that they can communicate with you securely. If +they don't have GnuPG, they will be able to read your message and see your +signature. If they do have GnuPG, they'll also be able to verify that your +signature is authentic.

+ +

To sign an email to Edward, compose any message to him and click the +pencil icon next to the lock icon so that it turns gold. If you sign a +message, GnuPG may ask you for your password before it sends the message, +because it needs to unlock your private key for signing.

+ +

With the lock and pencil icons, you can choose whether each message will +be encrypted, signed, both, or neither.

+ +
+
+ + +
+
+ +

Step 3.e Receive a response

+ +

When Edward receives your email, he will use your public key (which you +sent him in Step 3.A) to verify that your signature +is authentic and the message you sent has not been tampered with.

+ +

It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide.

+ +

Edward's reply will arrive encrypted, because he prefers to use encryption +whenever possible. If everything goes according to plan, it should say +"Your signature was verified." If your test signed email was also encrypted, +he will mention that first.

+ +
+
+ + + +
+ + +
+ +

#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've verified +that it belongs to them and not someone else.

+ +

Signing keys and signing messages use the same type of 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 who use your public key can see who has signed it. Once you've +used GnuPG for a long time, your key may have hundreds of signatures. You +can consider a key to be more trustworthy if it has many signatures from +people that you trust. The Web of Trust is a constellation of GnuPG users, +connected to each other by chains of trust expressed through signatures.

+ +
+ + +
+ +
+ +

Step 4.a Sign a key

+ +

In your email program's menu, go to Enigmail → Key Management.

+ +

Right click on Edward's public key and select Sign Key from the context +menu.

+ +

In the window that pops up, select "I will not answer" and click ok.

+ +

Now you should be back at the Key Management menu. Select Keyserver → +Upload Public Keys and hit ok.

+ +

You've just effectively said "I trust that Edward's public +key actually belongs to Edward." This doesn't mean much because Edward isn't +a real person, but it's good practice.

+ + +
+
+ + +
+
+ +

Identifying keys: Fingerprints and IDs

+ +

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.

+ +

You may also see public keys referred to by their key ID, +which is simply the last eight 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 you are trying to communicate to verify which one to use.

+ +
+
+ + +
+
+ +

Important: What to consider when signing keys

+ +

Before signing a person's key, you need to be confident that it actually +belongs to them, and that they are who they say they are. Ideally, this +confidence comes from having interactions and conversations with them over +time, and witnessing interactions between them and others. Whenever signing +a key, ask to see the full public key fingerprint, and not just the shorter +key ID. If you feel it's important to sign the key of someone you've just +met, also ask them to show you their government identification, and make +sure the name on the ID matches the name on the public key. 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?"

+ + +
+ +

Advanced

+ +
+
Master the Web of Trust
+
Unfortunately, trust does not spread between users the way many people +think. One of best ways to strengthen the GnuPG community is to deeply understand the Web of +Trust and to carefully sign as many people's keys as circumstances permit.
+ +
Set ownertrust
+
If you trust someone enough to validate other people's keys, you can assign +them an ownertrust level through Enigmails's key management window. Right +click on the other person's key, go to the "Select Owner Trust" menu option, +select the trustlevel and click OK. Only do this once you feel you have a +deep understanding of the Web of Trust.
+
+ +
+
+
+
- + +
+ + +
+ +

#5 Use it well

+ +

Everyone uses GnuPG a little differently, but it's important to follow +some basic practices to keep your email secure. Not following them, you +risk the privacy of the people you communicate with, as well as your own, +and damage the Web of Trust.

+ +
+ + +
+ +
+ +

When should I encrypt? When should I sign?

+ +

The more you can encrypt your messages, the better. 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. 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.

+ +

Unless you don't want to reveal your own identity (which requires other +protective measures), there's no reason not to sign every message, whether or +not you are encrypting. In addition to allowing those with GnuPG to verify +that the message came from you, signing is a non-intrusive way to remind +everyone that you use GnuPG and show support for secure communication. If you +often send signed messages to people that aren't familiar with GnuPG, it's +nice to also include a link to this guide in your standard email signature +(the text kind, not the cryptographic kind).

+ +
+
+ + +
+ +
+ +

Be wary of invalid keys

+ +

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.

+ +

In your email program, go back to the first encrypted email that Edward +sent you. Because Edward encrypted it with your public key, it will have a +message from Enigmail at the top, which most likely says "Enigmail: Part of +this message encrypted."

+ +

When using GnuPG, make a habit of glancing at that bar. The program +will warn you there if you get an email encrypted with a key that can't +be trusted.

+ +
+
+ + +
+
+ +

Copy your revocation certificate to somewhere safe

+ +

Remember when you created your keys and saved the revocation certificate +that GnuPG made? It's time to copy that certificate 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, not on a device you carry with +you regularly.

+ +

If your private key ever gets lost or stolen, you'll need this certificate +file to let people know that you are no longer using that keypair.

+ +
+
+ + +
+
+ +

Important: act swiftly if someone gets your private key

+ +

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 read your encrypted email or forge your signature. This +guide doesn't cover how to revoke a key, but you can follow these instructions. +After you're done revoking, make a new key and send an email to everyone +with whom you usually use your key to make sure they know, including a copy +of your new key.

+ +
+
+ + + + + +
+
+ +

Webmail and GnuPG

+ +

When you use a web browser to access your email, you're using webmail, +an email program stored on a distant website. Unlike webmail, your desktop +email program runs on your own computer. Although webmail can't decrypt +encrypted email, it will still display it in its encrypted form. If you +primarily use webmail, you'll know to open your email client when you receive +a scrambled email.

Before searching the Web, we recommend you start by asking other people +who use your email system, to figure out the correct settings.
+ + + +
+ +
+
+
+ + +
+
+ +

Step 1.b Get GnuPG by downloading GPGTools

+ +

GPGTools is a software package that includes GnuPG. Download and install it, choosing +default options whenever asked. After it's installed, you can close any +windows that it creates.

+ +
+
+ + +
+ +
+ +

Step 1.c Install the Enigmail plugin for your email program

+ +

In your email program's menu, select Add-ons (it may be in the Tools +section). Make sure Extensions is selected on the left. Do you see Enigmail? If +so, skip this step.

+ +

If not, search "Enigmail" with the search bar in the upper right. You +can take it from here. Restart your email program when you're done.

+ +
+ +

Troubleshooting

+ +
+
I can't find the menu.
+
In many new email programs, the main menu is represented by an image of +three stacked horizontal bars.
+ + + +
+ +
+
+
+
+ + +
+ + +
+ +

#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 a phonebook; people who want to send you encrypted email can +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 together 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. 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, which are listed +in the order they appear:

+ +
    +
  • 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! You can +do it manually, or you can use the Diceware method. Doing it manually +is faster but not as secure. Using Diceware takes longer and requires +dice, but creates a password that is much harder for attackers figure +out. To use it, read the section "Make a secure passphrase with Diceware" in this +article by Micah Lee.
  • +
+ +

If you'd like to pick a password manually, come up with something +you can remember 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.

+ +

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). This step is essential for your +email self-defense, as you'll learn more about in Section +5.

+ + +
+ +

Troubleshooting

+ +
+
I can't find the Enigmail menu.
+
In many new email programs, the main menu is represented by an image +of three stacked horizontal bars. Enigmail may be inside a section called +Tools.
+ +
My email looks weird
+
Enigmail doesn't tend to play nice with HTML, which is used to format +emails, so it may disable your HTML formatting automatically. To send an +HTML-formatted email without encryption or a signature, hold down the Shift +key when you select compose. You can then write an email as if Enigmail +wasn't there.
+ +

+ +

Advanced

+ +
+
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 +recommends. Also make sure your key is at least 2048 bits, or 4096 if you +want to be extra 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.
+
+ +
+
+
+ + +
+
+ +

Step 2.b Upload your public key to a keyserver

+ +

In your email program's menu, select Enigmail → Key Management.

+ +

Right click on your key and select Upload Public Keys to Keyserver. Use +the default keyserver in the popup.

+ +

Now someone who wants to send you an encrypted message can +download your public key from the Internet. There are multiple keyservers +that you can select from the menu when you upload, but they are all copies +of each other, so it doesn't matter which one you use. However, it sometimes +takes a few hours for them to match each other when a new key is uploaded.

+ + +
+ +

Troubleshooting

+ +
+
The progress bar never finishes
+
Close the upload popup, make sure you are connected to the Internet, +and try again. If that doesn't work, try again, selecting a different +keyserver.
+ +
My key doesn't appear in the list
+
Try checking "Display All Keys by Default."
+ +

You can also upload your keys to a keyserver through the command line. The sks Web site +maintains a list of highly interconnected keyservers. You can also directly export +your key as a file on your computer.
+
+ +
+

+ + +
+
+ +

GnuPG, OpenPGP, what?

+ +

In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP +are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the +encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG) +is the program that implements the standard. Enigmail is a plug-in program +for your email program that provides an interface for GnuPG.

+ +
+
+
+ + +
+ + +
+ +

#3 Try it out!

+ +

Now you'll try a test correspondence with a computer program named Edward, +who knows how to use encryption. Except where noted, these are the same +steps you'd follow when corresponding with a real, live person.

+ + +
+ + +
+ +
+ +

Step 3.a Send Edward your public key

+ +

This is a special step that you won't have to do when corresponding +with real people. In your email program's menu, go to Enigmail → Key +Management. You should see your key in the list that pops up. Right click +on your key and select Send Public Keys by Email. This will create a new +draft message, as if you had just hit the Write button.

+ +

Address the message to edward-en@fsf.org. Put at least one word +(whatever you want) in the subject and body of the email. Don't send yet.

+ +

The lock icon in the top left should be yellow, meaning encryption is +turned on. We want this first special message to be unencrypted, so +click the icon once to turn it off. The lock should become grey, with a +blue dot on it (to alert you that the setting has been changed from the +default). Once encryption is off, hit Send.

+ +

It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide. Once he's responded, +head to the next step. From here on, you'll be doing just the same thing as +when corresponding with a real person.

+ +

When you open Edward's reply, GnuPG may prompt you for your password +before using your private key to decrypt it.

+ +
+
+ + +
+
+ +

Step 3.b Send a test encrypted email

+ +

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.

+ +

The lock icon in the top left of the window should be yellow, meaning +encryption is on. This will be your default from now on.

+ +

Next to the lock, you'll notice an icon of a pencil. We'll +get to this in a moment.

+ +

Click Send. Enigmail will pop up a window that says "Recipients not valid, +not trusted or not found."

+ +

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 C), then select ok. Select +ok in the next pop-up.

+ +

Now you are back at the "Recipients not valid, not trusted or not found" +screen. Check the box in front of Edward's key and click Send.

+ +

Since you encrypted this email with Edward's public key, +Edward's private key is required to decrypt it. Edward is the only one with +his private key, so no one except him can decrypt it.

+ + +
+ +

Troubleshooting

+ +
+
Enigmail can't find Edward's key
+
Close the pop-ups that have appeared since you clicked Send. Make sure +you are connected to the Internet and try again. If that doesn't work, repeat +the process, choosing a different keyserver when it asks you to pick one.
+ +
Unscrambled messages in the Sent folder
+
Even though you can't decrypt messages encrypted to someone else's key, +your email program will automatically save a copy encrypted to your public key, +which you'll be able to view from the Sent folder like a normal email. This +is normal, and it doesn't mean that your email was not sent encrypted.

Important: Security tips

+

Even if you encrypt your email, the subject line is not encrypted, so +don't put private information there. The sending and receiving addresses +aren't encrypted either, so a surveillance system can still figure out who +you're communicating with. Also, surveillance agents will know that you're +using GnuPG, even if they can't figure out what you're saying. When you +send attachments, Enigmail will give you the choice to encrypt them or not, +independent of the actual email.

+ + - + +
+
+ +

Step 3.c Receive a response

+ +

When Edward receives your email, he will use his private key to decrypt +it, then use your public key (which you sent him in Step +3.A) to encrypt his reply to you.

+ +

It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide.

+ +

When you receive Edward's email and open it, Enigmail will automatically +detect that it is encrypted with your public key, and then it will use your +private key to decrypt it.

+ +

Notice the bar that Enigmail shows you above the message, with information +about the status of Edward's key.

+ +
+
+ + +
+
+ +

Step 3.d Send a test signed email

+ +

GnuPG includes a way for you to sign messages and files, verifying that +they came from you and that they weren't tampered with along the way. These +signatures are stronger than their pen-and-paper cousins -- they're impossible +to forge, because they're impossible to create without your private key +(another reason to keep your private key safe).

+ +

You can sign messages to anyone, so it's a great way to make people +aware that you use GnuPG and that they can communicate with you securely. If +they don't have GnuPG, they will be able to read your message and see your +signature. If they do have GnuPG, they'll also be able to verify that your +signature is authentic.

+ +

To sign an email to Edward, compose any message to him and click the +pencil icon next to the lock icon so that it turns gold. If you sign a +message, GnuPG may ask you for your password before it sends the message, +because it needs to unlock your private key for signing.

+ +

With the lock and pencil icons, you can choose whether each message will +be encrypted, signed, both, or neither.

+ +
+
+ + +
+
+ +

Step 3.e Receive a response

+ +

When Edward receives your email, he will use your public key (which you +sent him in Step 3.A) to verify that your signature +is authentic and the message you sent has not been tampered with.

+ +

It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide.

+ +

Edward's reply will arrive encrypted, because he prefers to use encryption +whenever possible. If everything goes according to plan, it should say +"Your signature was verified." If your test signed email was also encrypted, +he will mention that first.

+ +
+
+ + + +
+ + +
+ +

#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've verified +that it belongs to them and not someone else.

+ +

Signing keys and signing messages use the same type of 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 who use your public key can see who has signed it. Once you've +used GnuPG for a long time, your key may have hundreds of signatures. You +can consider a key to be more trustworthy if it has many signatures from +people that you trust. The Web of Trust is a constellation of GnuPG users, +connected to each other by chains of trust expressed through signatures.

+ +
+ + +
+ +
+ +

Step 4.a Sign a key

+ +

In your email program's menu, go to Enigmail → Key Management.

+ +

Right click on Edward's public key and select Sign Key from the context +menu.

+ +

In the window that pops up, select "I will not answer" and click ok.

+ +

Now you should be back at the Key Management menu. Select Keyserver → +Upload Public Keys and hit ok.

+ +

You've just effectively said "I trust that Edward's public +key actually belongs to Edward." This doesn't mean much because Edward isn't +a real person, but it's good practice.

+ + +
+
+ + +
+
+ +

Identifying keys: Fingerprints and IDs

+ +

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.

+ +

You may also see public keys referred to by their key ID, +which is simply the last eight 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 you are trying to communicate to verify which one to use.

+ +
+
+ + +
+
+ +

Important: What to consider when signing keys

+ +

Before signing a person's key, you need to be confident that it actually +belongs to them, and that they are who they say they are. Ideally, this +confidence comes from having interactions and conversations with them over +time, and witnessing interactions between them and others. Whenever signing +a key, ask to see the full public key fingerprint, and not just the shorter +key ID. If you feel it's important to sign the key of someone you've just +met, also ask them to show you their government identification, and make +sure the name on the ID matches the name on the public key. 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?"

+ + +
+ +

Advanced

+ +
+
Master the Web of Trust
+
Unfortunately, trust does not spread between users the way many people +think. One of best ways to strengthen the GnuPG community is to deeply understand the Web of +Trust and to carefully sign as many people's keys as circumstances permit.
+ +
Set ownertrust
+
If you trust someone enough to validate other people's keys, you can assign +them an ownertrust level through Enigmails's key management window. Right +click on the other person's key, go to the "Select Owner Trust" menu option, +select the trustlevel and click OK. Only do this once you feel you have a +deep understanding of the Web of Trust.
+
+ +
+
+
+
+ + +
+ + +
+ +

#5 Use it well

+ +

Everyone uses GnuPG a little differently, but it's important to follow +some basic practices to keep your email secure. Not following them, you +risk the privacy of the people you communicate with, as well as your own, +and damage the Web of Trust.

+ +
+ + +
+ +
+ +

When should I encrypt? When should I sign?

+ +

The more you can encrypt your messages, the better. 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. 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.

+ +

Unless you don't want to reveal your own identity (which requires other +protective measures), there's no reason not to sign every message, whether or +not you are encrypting. In addition to allowing those with GnuPG to verify +that the message came from you, signing is a non-intrusive way to remind +everyone that you use GnuPG and show support for secure communication. If you +often send signed messages to people that aren't familiar with GnuPG, it's +nice to also include a link to this guide in your standard email signature +(the text kind, not the cryptographic kind).

+ +
+
+ + +
+ +
+ +

Be wary of invalid keys

+ +

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.

+ +

In your email program, go back to the first encrypted email that Edward +sent you. Because Edward encrypted it with your public key, it will have a +message from Enigmail at the top, which most likely says "Enigmail: Part of +this message encrypted."

+ +

When using GnuPG, make a habit of glancing at that bar. The program +will warn you there if you get an email encrypted with a key that can't +be trusted.

+ +
+
+ + +
+
+ +

Copy your revocation certificate to somewhere safe

+ +

Remember when you created your keys and saved the revocation certificate +that GnuPG made? It's time to copy that certificate 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, not on a device you carry with +you regularly.

+ +

If your private key ever gets lost or stolen, you'll need this certificate +file to let people know that you are no longer using that keypair.

+ +
+
+ + +
+
+ +

Important: act swiftly if someone gets your private key

+ +

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 read your encrypted email or forge your signature. This +guide doesn't cover how to revoke a key, but you can follow these instructions. +After you're done revoking, make a new key and send an email to everyone +with whom you usually use your key to make sure they know, including a copy +of your new key.

+ +
+
+ + + + + +
+
+ +

Webmail and GnuPG

+ +

When you use a web browser to access your email, you're using webmail, +an email program stored on a distant website. Unlike webmail, your desktop +email program runs on your own computer. Although webmail can't decrypt +encrypted email, it will still display it in its encrypted form. If you +primarily use webmail, you'll know to open your email client when you receive +a scrambled email.

    #1 Get the pieces

    + +

    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). To +defend your freedom as well as protect yourself from surveillance, we recommend +you switch to a free software operating system like GNU/Linux. Learn more +about free software at fsf.org.

    + +

    To get started, you'll need the IceDove desktop email program installed +on your computer. For your system, IceDove may be known by the alternate name +"Thunderbird." Email programs are another way to access the same email accounts +you can access in a browser (like Gmail), but provide extra features.

    + +

    If you already have an email program, you can skip to Step 1.b.

    + +
    + + +
    + +
    + +

    Step 1.a Set up your email program with your email account

    + +

    Open your email program and follow the wizard (step-by-step walkthrough) +that sets it up with your email account.

    + + +
    + +

    Troubleshooting

    + +
    +
    The wizard doesn't launch
    +
    You can launch the wizard yourself, but the menu option for doing so is +named differently in each email programs. The button to launch it will be in +the program's main menu, under "New" or something similar, titled something +like "Add account" or "New/Existing email account."
    + +
    The wizard can't find my account or isn't downloading my mail
    +
    Before searching the Web, we recommend you start by asking other people +who use your email system, to figure out the correct settings.
    + + + +
    + +
    +
    +
    + + +
    +
    + +

    Step 1.b Get GnuPG by downloading GPG4Win

    + +

    GPG4Win is a software package that includes GnuPG. Download and install it, choosing default +options whenever asked. After it's installed, you can close any windows that +it creates.

    + +
    +
    + + +
    + +
    + +

    Step 1.c Install the Enigmail plugin for your email program

    + +

    In your email program's menu, select Add-ons (it may be in the Tools +section). Make sure Extensions is selected on the left. Do you see Enigmail? If +so, skip this step.

    + +

    If not, search "Enigmail" with the search bar in the upper right. You +can take it from here. Restart your email program when you're done.

    + +
    + +

    Troubleshooting

    + +
    +
    I can't find the menu.
    +
    In many new email programs, the main menu is represented by an image of +three stacked horizontal bars.
    + + + +
    + +
    +
    +
    +
    + + +
    + + +
    + +

    #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 a phonebook; people who want to send you encrypted email can +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 together 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. 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, which are listed +in the order they appear:

    + +
      +
    • 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! You can +do it manually, or you can use the Diceware method. Doing it manually +is faster but not as secure. Using Diceware takes longer and requires +dice, but creates a password that is much harder for attackers figure +out. To use it, read the section "Make a secure passphrase with Diceware" in this +article by Micah Lee.
    • +
    + +

    If you'd like to pick a password manually, come up with something +you can remember 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.

    + +

    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). This step is essential for your +email self-defense, as you'll learn more about in Section +5.

    + + +
    + +

    Troubleshooting

    + +
    +
    I can't find the Enigmail menu.
    +
    In many new email programs, the main menu is represented by an image +of three stacked horizontal bars. Enigmail may be inside a section called +Tools.
    + +
    More resources
    +
    If you're having trouble with our +instructions or just want to learn more, check out Enigmail's +wiki instructions for key generation.
    + +
    My email looks weird
    +
    Enigmail doesn't tend to play nice with HTML, which is used to format +emails, so it may disable your HTML formatting automatically. To send an +HTML-formatted email without encryption or a signature, hold down the Shift +key when you select compose. You can then write an email as if Enigmail +wasn't there.
    + + + +
    + +
    + + +
    + +

    Advanced

    + +
    +
    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 +recommends. Also make sure your key is at least 2048 bits, or 4096 if you +want to be extra 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.
    +
    + +
    +
    +
    + + +
    +
    + +

    Step 2.b Upload your public key to a keyserver

    + +

    In your email program's menu, select Enigmail → Key Management.

    + +

    Right click on your key and select Upload Public Keys to Keyserver. Use +the default keyserver in the popup.

    + +

    Now someone who wants to send you an encrypted message can +download your public key from the Internet. There are multiple keyservers +that you can select from the menu when you upload, but they are all copies +of each other, so it doesn't matter which one you use. However, it sometimes +takes a few hours for them to match each other when a new key is uploaded.

    + + +
    + +

    Troubleshooting

    + +
    +
    The progress bar never finishes
    +
    Close the upload popup, make sure you are connected to the Internet, +and try again. If that doesn't work, try again, selecting a different +keyserver.
    + +
    My key doesn't appear in the list
    +
    Try checking "Display All Keys by Default."
    + +
    More documentation
    +
    If you're having trouble with our +instructions or just want to learn more, check out Enigmail's +documentation.
    + + + +
    + +
    + + +
    + +

    Advanced

    + +
    +
    Uploading a key from the command line
    +
    You can also upload your keys to a keyserver through the command line. The sks Web site +maintains a list of highly interconnected keyservers. You can also directly export +your key as a file on your computer.
    +
    + +
    +
    +
    + + +
    +
    + +

    GnuPG, OpenPGP, what?

    + +

    In general, the terms GnuPG, GPG, GNU Privacy Guard, OpenPGP and PGP +are used interchangeably. Technically, OpenPGP (Pretty Good Privacy) is the +encryption standard, and GNU Privacy Guard (often shortened to GPG or GnuPG) +is the program that implements the standard. Enigmail is a plug-in program +for your email program that provides an interface for GnuPG.

    + +
    +
    +
    + + +
    + + +
    + +

    #3 Try it out!

    + +

    Now you'll try a test correspondence with a computer program named Edward, +who knows how to use encryption. Except where noted, these are the same +steps you'd follow when corresponding with a real, live person.

    + + +
    + + +
    + +
    + +

    Step 3.a Send Edward your public key

    + +

    This is a special step that you won't have to do when corresponding +with real people. In your email program's menu, go to Enigmail → Key +Management. You should see your key in the list that pops up. Right click +on your key and select Send Public Keys by Email. This will create a new +draft message, as if you had just hit the Write button.

    + +

    Address the message to edward-en@fsf.org. Put at least one word +(whatever you want) in the subject and body of the email. Don't send yet.

    + +

    The lock icon in the top left should be yellow, meaning encryption is +turned on. We want this first special message to be unencrypted, so +click the icon once to turn it off. The lock should become grey, with a +blue dot on it (to alert you that the setting has been changed from the +default). Once encryption is off, hit Send.

    + +

    It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide. Once he's responded, +head to the next step. From here on, you'll be doing just the same thing as +when corresponding with a real person.

    + +

    When you open Edward's reply, GnuPG may prompt you for your password +before using your private key to decrypt it.

    + +
    +
    + + +
    +
    + +

    Step 3.b Send a test encrypted email

    + +

    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.

    + +

    The lock icon in the top left of the window should be yellow, meaning +encryption is on. This will be your default from now on.

    + +

    Next to the lock, you'll notice an icon of a pencil. We'll +get to this in a moment.

    + +

    Click Send. Enigmail will pop up a window that says "Recipients not valid, +not trusted or not found."

    + +

    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 C), then select ok. Select +ok in the next pop-up.

    + +

    Now you are back at the "Recipients not valid, not trusted or not found" +screen. Check the box in front of Edward's key and click Send.

    + +

    Since you encrypted this email with Edward's public key, +Edward's private key is required to decrypt it. Edward is the only one with +his private key, so no one except him can decrypt it.

    + + +
    + +

    Troubleshooting

    + +
    +
    Enigmail can't find Edward's key
    +
    Close the pop-ups that have appeared since you clicked Send. Make sure +you are connected to the Internet and try again. If that doesn't work, repeat +the process, choosing a different keyserver when it asks you to pick one.
    + +
    Unscrambled messages in the Sent folder
    +
    Even though you can't decrypt messages encrypted to someone else's key, +your email program will automatically save a copy encrypted to your public key, +which you'll be able to view from the Sent folder like a normal email. This +is normal, and it doesn't mean that your email was not sent encrypted.

    Advanced

    + +
    +
    Encrypt messages from the command line
    +
    You can also encrypt and decrypt messages and files from the command line, +if that's your preference. The option --armor makes the encrypted output +appear in the regular character set.

    Important: Security tips

    +

    Even if you encrypt your email, the subject line is not encrypted, so +don't put private information there. The sending and receiving addresses +aren't encrypted either, so a surveillance system can still figure out who +you're communicating with. Also, surveillance agents will know that you're +using GnuPG, even if they can't figure out what you're saying. When you +send attachments, Enigmail will give you the choice to encrypt them or not, +independent of the actual email.

    + + - + +
    +
    + +

    Step 3.c Receive a response

    + +

    When Edward receives your email, he will use his private key to decrypt +it, then use your public key (which you sent him in Step +3.A) to encrypt his reply to you.

    + +

    It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide.

    + +

    When you receive Edward's email and open it, Enigmail will automatically +detect that it is encrypted with your public key, and then it will use your +private key to decrypt it.

    + +

    Notice the bar that Enigmail shows you above the message, with information +about the status of Edward's key.

    + +
    +
    + + +
    +
    + +

    Step 3.d Send a test signed email

    + +

    GnuPG includes a way for you to sign messages and files, verifying that +they came from you and that they weren't tampered with along the way. These +signatures are stronger than their pen-and-paper cousins -- they're impossible +to forge, because they're impossible to create without your private key +(another reason to keep your private key safe).

    + +

    You can sign messages to anyone, so it's a great way to make people +aware that you use GnuPG and that they can communicate with you securely. If +they don't have GnuPG, they will be able to read your message and see your +signature. If they do have GnuPG, they'll also be able to verify that your +signature is authentic.

    + +

    To sign an email to Edward, compose any message to him and click the +pencil icon next to the lock icon so that it turns gold. If you sign a +message, GnuPG may ask you for your password before it sends the message, +because it needs to unlock your private key for signing.

    + +

    With the lock and pencil icons, you can choose whether each message will +be encrypted, signed, both, or neither.

    + +
    +
    + + +
    +
    + +

    Step 3.e Receive a response

    + +

    When Edward receives your email, he will use your public key (which you +sent him in Step 3.A) to verify that your signature +is authentic and the message you sent has not been tampered with.

    + +

    It may take two or three minutes for Edward to +respond. In the meantime, you might want to skip ahead and check out the Use it Well section of this guide.

    + +

    Edward's reply will arrive encrypted, because he prefers to use encryption +whenever possible. If everything goes according to plan, it should say +"Your signature was verified." If your test signed email was also encrypted, +he will mention that first.

    + +
    +
    + + + +
    + + +
    + +

    #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've verified +that it belongs to them and not someone else.

    + +

    Signing keys and signing messages use the same type of 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 who use your public key can see who has signed it. Once you've +used GnuPG for a long time, your key may have hundreds of signatures. You +can consider a key to be more trustworthy if it has many signatures from +people that you trust. The Web of Trust is a constellation of GnuPG users, +connected to each other by chains of trust expressed through signatures.

    + +
    + + +
    + +
    + +

    Step 4.a Sign a key

    + +

    In your email program's menu, go to Enigmail → Key Management.

    + +

    Right click on Edward's public key and select Sign Key from the context +menu.

    + +

    In the window that pops up, select "I will not answer" and click ok.

    + +

    Now you should be back at the Key Management menu. Select Keyserver → +Upload Public Keys and hit ok.

    + +

    You've just effectively said "I trust that Edward's public +key actually belongs to Edward." This doesn't mean much because Edward isn't +a real person, but it's good practice.

    + + +
    +
    + + +
    +
    + +

    Identifying keys: Fingerprints and IDs

    + +

    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.

    + +

    You may also see public keys referred to by their key ID, +which is simply the last eight 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 you are trying to communicate to verify which one to use.

    + +
    +
    + + +
    +
    + +

    Important: What to consider when signing keys

    + +

    Before signing a person's key, you need to be confident that it actually +belongs to them, and that they are who they say they are. Ideally, this +confidence comes from having interactions and conversations with them over +time, and witnessing interactions between them and others. Whenever signing +a key, ask to see the full public key fingerprint, and not just the shorter +key ID. If you feel it's important to sign the key of someone you've just +met, also ask them to show you their government identification, and make +sure the name on the ID matches the name on the public key. 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?"

    + + +
    + +

    Advanced

    + +
    +
    Master the Web of Trust
    +
    Unfortunately, trust does not spread between users the way many people +think. One of best ways to strengthen the GnuPG community is to deeply understand the Web of +Trust and to carefully sign as many people's keys as circumstances permit.
    + +
    Set ownertrust
    +
    If you trust someone enough to validate other people's keys, you can assign +them an ownertrust level through Enigmails's key management window. Right +click on the other person's key, go to the "Select Owner Trust" menu option, +select the trustlevel and click OK. Only do this once you feel you have a +deep understanding of the Web of Trust.
    +
    + +
    +
    +
    +
    + + +
    + + +
    + +

    #5 Use it well

    + +

    Everyone uses GnuPG a little differently, but it's important to follow +some basic practices to keep your email secure. Not following them, you +risk the privacy of the people you communicate with, as well as your own, +and damage the Web of Trust.

    + +
    + + +
    + +
    + +

    When should I encrypt? When should I sign?

    + +

    The more you can encrypt your messages, the better. 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. 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.

    + +

    Unless you don't want to reveal your own identity (which requires other +protective measures), there's no reason not to sign every message, whether or +not you are encrypting. In addition to allowing those with GnuPG to verify +that the message came from you, signing is a non-intrusive way to remind +everyone that you use GnuPG and show support for secure communication. If you +often send signed messages to people that aren't familiar with GnuPG, it's +nice to also include a link to this guide in your standard email signature +(the text kind, not the cryptographic kind).

    + +
    +
    + + +
    + +
    + +

    Be wary of invalid keys

    + +

    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.

    + +

    In your email program, go back to the first encrypted email that Edward +sent you. Because Edward encrypted it with your public key, it will have a +message from Enigmail at the top, which most likely says "Enigmail: Part of +this message encrypted."

    + +

    When using GnuPG, make a habit of glancing at that bar. The program +will warn you there if you get an email encrypted with a key that can't +be trusted.

    + +
    +
    + + +
    +
    + +

    Copy your revocation certificate to somewhere safe

    + +

    Remember when you created your keys and saved the revocation certificate +that GnuPG made? It's time to copy that certificate 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, not on a device you carry with +you regularly.

    + +

    If your private key ever gets lost or stolen, you'll need this certificate +file to let people know that you are no longer using that keypair.

    + +
    +
    + + +
    +
    + +

    Important: act swiftly if someone gets your private key

    + +

    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 read your encrypted email or forge your signature. This +guide doesn't cover how to revoke a key, but you can follow these instructions. +After you're done revoking, make a new key and send an email to everyone +with whom you usually use your key to make sure they know, including a copy +of your new key.

    + +
    +
    + + + + + +
    +
    + +

    Webmail and GnuPG

    + +

    When you use a web browser to access your email, you're using webmail, +an email program stored on a distant website. Unlike webmail, your desktop +email program runs on your own computer. Although webmail can't decrypt +encrypted email, it will still display it in its encrypted form. If you +primarily use webmail, you'll know to open your email client when you receive +a scrambled email.

    #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 talking points 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

    -

    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?

    -
    +

    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 who need privacy +the most, 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.

    + +

    We shouldn't have to trust our email providers with our privacy

    -

    Some email providers are very trustworthy, but many have incentives not to protect your privacy and security. To be empowered digital citizens, we need to build our own security from the bottom up.

    -
    +

    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 whom your community will +likely recognize.

    #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). If you'd like to make it easy for the participants to use Diceware for choosing passwords, get a pack of dice beforehand. 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 at least forty minutes plus ten minutes for each participant. 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 high by recruiting more facilitators, or by facilitating multiple workshops. Small workshops among friends work great!

    +

    There's no objective way to judge what constitutes 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 correspondence with them.

    #3 Follow the guide as a group

    -

    Work through the Email Self-Defense guide a step at a 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.

    -

    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 test messages to each other instead of or as well as Edward. Similarly, in Section 4, encourage the participants to sign each other's keys. At the end, make sure to remind people to safely back up their revocation certificates.

    #4 Explain the pitfalls

    -

    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.

    -

    Explain the dangers of running a proprietary system and advocate for free software, because without it, we can't meaningfully resist invasions of our digital privacy and autonomy.

    #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

    -

    Make sure everyone has shared email addresses and public key fingerprints before they leave. Encourage the participants to continue to gain GnuPG experience by emailing each other. Send them each an encrypted email one week after the event, reminding them to try adding their public key ID to places where they publicly list their email address.
