There should be an icon of a yellow key in the bottom right of the composition window. This means that encryption is on, however, we want this first special message to Edward to be unencrypted. Click the key icon once to turn encryption off. The key 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.

Advanced

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, Enigmail may prompt you for your password before using your private key to decrypt it.

- +

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.

- -

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 key in the bottom right of the window should be yellow, meaning encryption is on. This will be your default from now on.

Next to the key, you'll notice an icon of a pencil. Clicking this tells Enigmail to add a special, unique signature to your message, generated using your private key. This is a separate feature from encryption, and you don't have to use it for this guide.

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

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.

+ +

+ -

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 — not even you — can decrypt it.

- + +

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

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.

Important: Security tips

Even if you encrypted 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 they could be read by a surveillance system. When you send attachments, Enigmail will give you an option of whether you want to encrypt them.

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.

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.

#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.

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.

+ +

#4 Learn 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 someone else.

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.

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.

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.

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.

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?".

Identifying keys: Fingerprints and IDs

+ +

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.

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.

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 second 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.

#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.

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:

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!

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.

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.

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 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.

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."

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.
