![]() ![]() To do this, Go to Preferences -> General -> Manage Plug-ins and enable the GPGMailLoader.mailbundle plug-in. If youre using an up-to-date version of macOS (10.14 Mojave+), you will need to enable GPG in Mail. The next step is generate a public-private key pair, and publish your public key (so others can find your public key to send you encrypted email). Once you have found the key you want, simply import it into your GPG Keychain. After confirming that Thunderbird can send/receive email, Enigmail plug-in can be installed and configured to use the GPG on your platform. If you are on version 2.1.17 or greater, paste the text below to generate a GPG key pair. You don't need a new email account - this setup works with your existing email account. Since there are multiple versions of GPG, you may need to consult the relevant man page to find the appropriate key generation command. After that, the next step is to install Thunderbird, a mail client. There are instructions for Linux, Mac, and Windows below. The first step is to install GPG for your platform. Thunderbird is an email client, and Enigmail is the plug-in that uses GPG for that platform to integrate that into a user's email account. GPG is a tool that does several things, but mostly it is used to generate a public/private key pair and maintains a user's keychain - the set of public keys from all their contacts.

The creation of an open-source PGP version eliminated the issues regarding the export of cryptography while ensuring anyone could make use of the encryption tool.For an overview of how public key encryption works, this is an excellent explanation: Public Key Cryptography: Diffie-Hellman Key Exchange.

In fact, Zimmerman was investigated for breaching the Arms Export Control Act, such was the power of the PGP encryption tool at the time.ĭue to those restrictions, the OpenPGP Working Group was formed with help from the Internet Engineering Task Force (IEFT). Which meant exporting Zimmerman's PGP tool to international countries was a serious crime. OpenPGP: Up until 1992, cryptography featured on the US Munitions List as an Auxiliary Military Equipment. Now owned by Symantec but licensed by thousands of companies. PGP: Developed by Phil Zimmerman in 1991, PGP is one of the most enduring digital encryption methods and the most popular email encryption tool. Here's a quick history of PGP, OpenPGP, and GPG. Unless you're going to be buying a PGP-enabled product from Symantec, the company that currently owns the PGP copyright and company, you'll likely be using GPG. GPG is an open-source implementation of PGP, and works on the same principles. Throughout this article, I'll be discussing both PGP and Gnu Privacy Guard (GnuPG, or GPG). What's the Difference Between PGP, OpenPGP, and GnuPG? ![]() If even a single letter in the message is changed before it's decrypted, the signature will be invalidated, alerting the recipient to foul play. By signing your encrypted message with your private key, you provide a way for the recipient to see if the message content has been changed. In addition to encryption, PGP also allows for digital signatures. But it's also quite safe, as messages can only be decrypted with privately known keys that are password-protected. This system ensures that it's easy to send encrypted communications because the only thing needed to encrypt a message is a public key and the proper PGP program. If you don't have a GPG key that matches your committer identity, you need to associate an email with an existing key. It'll help make encryption terminology much easier to understand. If you're using a GPG key that matches your committer identity and your verified email address associated with your account on, then you can begin signing commits and signing tags. Unsure what a public key or a private key is? Check out these basic encryption terms before reading on. It works by encrypting a message using a public key that's tied to a specific user when that user receives the message, they use a private key that's known only to them to decrypt it. PGP stands for "Pretty Good Privacy." PGP is most often used for sending encrypted messages between two people. ![]()
