Binary package “pinentry-qt” in ubuntu bionic

Qt-based PIN or pass-phrase entry dialog for GnuPG

 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, so it is especially suitable for users of KDE.
 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.
