pinentry-curses - 1.2.1-4+b1 main

This package contains a program that allows for secure entry of PINs or
pass phrases. That means it tries to take care that the entered
information is not swapped to disk or temporarily stored anywhere.
This functionality is particularly 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 curses tool kit, meaning that it is useful for users
working in text mode without the X Window System. There are sibling
packages that implement PIN entry dialogs that use an X tool kit. If
you install any of the graphical packages then this package is not
necessary because the sibling packages automatically fall back to
text mode if X is not active.
