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.
