#1 Get the pieces

Before starting, you'll need any one of these desktop email programs installed on your computer: FossaMail (for Windows), Icedove (for Debian GNU/Linux), Thunderbird (for other GNU/Linux flavors, Apple OS X), or any other program based on one of these. If you are already using one of these, you can skip to Step 1.b.

An email program lets you read and write mail without using a Web browser, and provides special features that are hard to find in email systems you use in a Web browser. Using an email program doesn't mean that you have to make a new email account — most people just connect an existing email account from a Web email service (like GMail) or their workplace to their email program. You can think of it as another way to access the same email account.

Download it, run the executable and click through the installation wizard with all the default settings. You don't need to run the program once it's installed.

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.

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

#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 keypair is actually theirs. Otherwise, there would be no way to stop an attacker from making an email address with your friends name, creating a keypair to go with it and impersonating your friend. They would then be able to impersonate your friend by signing messages with the private key they'd created, and decrypt messages intended for your friend with the public key.

That's why the programmers that developed email encryption created keysigning and the Web of Trust. Keysigning allows a person to publicly state that they trust that a public key belongs to a specific person. To sign someone's public key, you need to use your private key, so the world will know that it was you.

Step 5a When should I encrypt? When should I sign?

Everyone uses GnuPG a little differently. Encryption is most important for messages involving finances, personal information, politically sensitive conversations and anything else that you wouldn't want to fall into the wrong hands. Signing is best for when you think there might be concern about your identity, or as a way of demonstrating that you know how to use GnuPG and will be able to decrypt emails. If you're already encrypting, there's no reason not to sign as well, to give the recipient added assurance that the message is from you.

Step 5c Make it part of your online identity

Start writing your key ID anywhere someone would see your email address. Add it to your email signature, social media profile, blog, Website, or business card.

Important: act swiftly if you lose your key

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