pinentry-tty(1)


NAME

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

SYNOPSIS

   pinentry-tty [OPTION...]

DESCRIPTION

   pinentry-tty  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-tty  implements a PIN entry prompt directly on the controlling
   tty.  It has minimal dependencies, and  a  comparably  minimal  feature
   set.   It  is  useful  for  users working with dumb terminals and other
   similarly constrained environments.  There are other  pinentry  flavors
   that  implement  more  user-friendly  PIN entry dialogs, either in text
   mode with the curses toolkit, or using graphical X11 toolkits.   Please
   use one of the other flavors unless you know what you are doing.

   pinentry-tty  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-tty;
          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-tty).

   --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-tty.  They are required because pinentry-tty 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.

   The full documentation for pinentry-tty  is  maintained  as  a  Texinfo
   manual.  If the pinentry-doc package is installed, the command

          info pinentry

   should give you access to the complete manual.
