Exporting the Encryption for Email Keys
You can export private and public keys.
You might want to export your private key if, for example, you are going to use a computer that has no network access but you have private files saved on it. You can save the private key to a disk or USB drive and then import it to the offline computer using the Encryption for Email Key Manager.
You might want to export your public key, for example, to make files private on an offline computer.
Open the Key Manager, as described in Opening the Key Manager.
Select the key to export from the key pane in the top right of the Encryption for Email Key Manager window.
Right-click the selected key and click Export Key from the menu.
The Save As window appears.
Keep the key name shown or rename it before saving it locally.
Note: The Encryption for Email Key Manager saves exported keys with a *.pppub file extension for public keys and a *.ppprv file extension for private keys.
Click Save. Encryption for Email exports the key and then displays a “successfully exported” message.
Click OK.
