pinentry-qt4 binary package in Ubuntu Precise armhf

 This package contains a program that allows for entry of PINs or pass
 phrases. It is useful for entering pass phrases when using encryption
 software such as GnuPG or e-mail clients using the same. It uses an open
 protocol and is therefore not tied to particular software.
 .
 The program contained in this package implements a PIN entry dialog
 using the Qt tool kit version 4, so it is especially suitable for
 users of KDE 4. If the X Window System is not active then an
 alternative text-mode dialog will be used. There are sibling
 packages that implement PIN entry dialogs using other tool kits.
