pinentry-qt(1)


NAME

   pinentry-qt - PIN or pass-phrase entry dialog for GnuPG

SYNOPSIS

   pinentry-qt [OPTION...]

DESCRIPTION

   pinentry-qt  is  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.

   pinentry-qt  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
   other flavors that implement PIN entry dialogs using other tool kits.

   pinentry-qt is typically used internally  by  gpg-agent.   Users  don't
   normally have a reason to call it directly.

OPTIONS

   --version
          Print the program version and licensing information.

   --help Print  a  usage message summarizing the most useful command-line
          options.

   --debug, -d
          Turn on some debugging.   Mostly  useful  for  the  maintainers.
          Note that this may reveal sensitive information like the entered
          pass phrase.

   --enhanced, -e
          Ask  for  timeouts  and  insurance,  too.   Note  that  this  is
          currently not fully supported.

   --no-global-grab, -g
          Grab  the  keyboard  only  when the window is focused.  Use this
          option  if  you  are  debugging  software   using   pinentry-qt;
          otherwise  you  may  not  be  able  to  to access your X session
          anymore (unless you have other means to connect to  the  machine
          to kill pinentry-qt).

   --parent-wid N
          Use window ID N as the parent window for positioning the window.
          Note, that this  is  not  fully  supported  by  all  flavors  of
          pinentry.

   --display STRING, --ttyname STRING, --ttytype STRING, --lc-type STRING,
   --lc-messages STRING
          These options are  used  to  pass  localization  information  to
          pinentry-qt.   They  are required because pinentry-qt is usually
          called by some  background  process  which  does  not  have  any
          information  on the locale and terminal to use.  Assuan protocol
          options are an alternative way to pass these information.
