Step 3.b Send a test encrypted email
Write a new email in your email program, addressed to email@example.com. Make the subject "Encryption test" or something similar and write something in the body. Don't send it yet.
Click the icon of the key in the bottom right of the composition window (it should turn yellow). This tells Enigmail to encrypt the email with the key you downloaded in the last step.
Next to the key, you'll notice an icon of a pencil. Clicking this tells Enigmail to add a special, uniqe 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."
To encrypt and email to Adele, you need her public key, and 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. Select Adele's key from the list and click Ok. If the message doesn't send automatically, you can hit send now.
- Enigmail can't find Adele's key
- Close the pop-ups that have appeared since you clicked. 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.
