We just revealed that there is more than one way to encrypt a file. So you can look at the instructions and maybe try different ways to decide which one suits you most. One possibility is to use Kleopatra which you probably used to create your own keys. Another tool that can be used is the component GpgEX.

Both Kleopatra and GpgEX are installed on your system if you followed this tutorial without any modifications.

Using Kleopatra

1. Click on Sign/Encrypt...




2. The file explorer will be opened. Navigate to the folder where the file is which you want to encrypt and click on this file.




3. Click on Open




4. In the field Encrypt for others start to enter the name of the email address of the person you want to encrypt the file to. In Jane's case she enters 'kim' to find Kim's key.




5. Click on the key of that email address to select it




6. Click on the button Sign /Encrypt




7. Enter the password/passphrase of your own key




8. Click on OK




9. Click on Finish

Using GpgEX

2. Right-click on the file you want to encrypt and click on the entry Sign and encrypt
