How to create a PGP/GPG key
One popular method for encrypting email is by using the Mozilla Thunderbird email client with the Enigmail plugin. The basic steps are:
- Download and install the Thunderbird client.
- Go to "Account Settings".
- Click on "End-to-End Encryption".
- Click on "Add Key" to either add an existing key or to generate a new one.
If you’re a MacOS user, you can also try GPGMail, a GPG plugin for Apple Mail.
