oPenGP Lite (couldn't find any version without the 'Lite'). This version works one way, it decrypts only, doesn't encrypt. This is a PGP Corporation (owned by Symantec now) App, hence the upper case PGP in oPenGP.
I don't know whether there is, or will be, a Mobile GnuPG what will work under iPhone or iPad iOS.
I generated on my Mac a new key pair (default RSA/RSA 2048). I didn't want to use my "regular" key.
Exported the secret key to the Mac's Desktop.
Connected the iPhone via iTunes (hardwired USB)
Imported the secret key to the iPhone via iTunes and an App called 'Files' <http://www.olivetoast.com/files/>.
In 'Files' I could see the key block, select all/copy.
Back to oPenGP, Import clipboard, ascertained that the key is now in the keyring.
Back to 'Files', set an access locked code. Checked that it works. Deleted the secret key keyblock.
Sent myself a test message encrypted with the public key of the above keypair.
Downloaded the e-mail in iPhone, select all/copy.
Back to oPenGP, Import/Decrypt Clipboard, enter the passphrase.
I don't feel at ease having my secret key in my iPhone, but i can learn to live with it, if I really want to use this iPhone feature. I'm not sure I want to.
So ios can use PGP on iphones and ipads?
What are the security issues? How safe is the private key and pass phrase on these devices?
