Atomichelix OpenPGP requires you to have a private key in order to receive encrypted
messages and to sign outgoing messages. You can import a private key that you have
from another PGP application by either: importing it from a file on an SD card
(Method #1 below), or imbedding it in an email message (Method #2 below).
This method is only available on devices with OS 4.5 and higher!
 |
Select "Private Keys" from the main screen menu in order to list all your private keys.
|
 |
You will have no private keys in the list, so exit the application.
|
 |
Start the "Media" application and open the menu. Navigate to "Explore" and
select it to begin navigating the filesystem.
|
 |
Navigate through the filesystem until you are in the directory that contains
the private key (as an "*.asc" or "*.ahk" file) you wish to import.
|
 |
Highlight the "*.asc" (or "*.ahk") file, open the menu, and select the "Open" menu item.
|
 |
When you open an "*.asc" (or "*.ahk") file attachment that contains a private key imbedded
in it, the prompt shown here will ask you if you wish to import it into your
own private key ring.
|
 |
If you respond with a "No", the private key will not be imported and you
will be returned directly to the media explorer. However, if you respond
with a "Yes", you will be prompted to enter the passphrase associated with
the private key, like the prompt shown here.
|
 |
You should then see the imported private key in the private key list, like
in this screenshot.
|
|
You will have no private keys in the list.
|
 |
Highlight the new private key, open the menu, and then select "Send Public
Key".
|
 |
Fill out your own email address (the one you have on your PC -- or wherever
you are going to send the private key from), and email the public key.
|
 |
Import the public key you sent to your PC into the program you use to send
encrypted messages with. In this example, we are using PGP Desktop to import
it.
|
 |
Copy and paste the ASCII-armoured private key into a new email and send
it to the device, encrypting it with the public key you just imported.
IMPORTANT: use the "PGP Partitioned" encryption setting for your
program. This will imbed the PGP block into the body of the email instead
of creating an encrypted attachment.
|
 |
Once you have decrypted the email, it will then prompt if you would like
to import the private key.
|
 |
If you select to import the private key, it will ask you for the passphrase
to that key (a maximum of 3 times). If you correctly enter the passphrase,
it will import the private key into the application. You will end up with
the original private key you created on the device and the one you imported
onto the device.
|
 |
OPTIONAL: You can now delete the private key you originally created
for the import, if you do not plan to use it and only use the imported one.
