How to transfer your Key pair:

Please select one of the below links, according to your Operating System:

• Windows
• macOS

Windows

1. On the machine where the encryption keys are stored, connect a USB drive to a free USB port.

2. Launch the Kleopatra application and select the encryption key you want to transfer. Then right-click on the selection and choose Backup Secret Keys...

Note: Do NOT use Export..., as this will only export the public part of the Key while you need to have a backup of both public and private parts.

3. Select your USB drive as destination and a filename of your preference (e.g. secret-key-KEYID.asc) for your backup copy. Then click Save.

4. Enter the passphrase you have set when you created the Key and click OK.

5. A pop-up will confirm the backup has been successfully created. Click OK.

6. Eject your USB drive safely through the Windows interface to prevent data loss and connect it to a free USB port on the other computer (the one you want to transfer the key to). All the next steps have to be executed on that machine.

7. Make sure the the GPA software is installed, otherwise please install it. Make sure that the component Kleopatra is selected as one of the sub components to include in the installation.

8. Launch the Kleopatra application and click on the top menu File and select Import...

9. Click on the letter correspondent to your USB drive and select the file you have previously saved (e.g. secret-key-KEYID.asc). Then click Open.

10. Click on Yes, It's Mine.
