OpenPGP Applet should display long keyid (or even only FP)
In the public key encryption interface of OpenPGP Applet, the keys are listed displaying the short hex key ID.
It doesn't really matter since it's not involved in fetching keys or the like, but it's good practice to always use the long hex keyid.
If only for the sake of consistency, OpenPGP applet should diplay long IDs too.
That said, long keyids are unsafe too (though a bit less so than short ones). Maybe we shouldn't display them at all and only show fingerprint ?
