For the encryption to work you need to install OpenKeychain app.

Initial configuration

and open End-to-end encryption category. First enable autocrypt mutual mode:

Your key is now configured. Note that it is highly recommended to add password to your key. For this and more options during key creation please refer to our OpenKeychain manual.

and select Advanced:

If you are certain you wish everyone to be able to use your public key, you can publish it a webserver (tap the option in light blue). Else, just share it with your friend via email:

Receiving and replying to encrypted email

Our friend received our email with our key attached, and imported it to his keychain. Now he is able to send us encrypted email:

Librem Mail 25

Green padlock icon tells us that this email is indeed encrypted, and only we can read it! Tap the padlock to check this:

Librem Mail 26

Now let’s reply back. First we need to import Haruto’s key to our keychain:

Librem Mail 27

Then create a reply:

Librem Mail 28

Again, green padlock icon informs us that this email will be encrypted for Haruto, and only he will be able to decrypt it with his key:

Librem Mail 29

Hit send (icon circled in blue) when you finish composing the email.
