NAME

       pinentry-qt4 - PIN or pass-phrase entry dialog for GnuPG

SYNOPSIS

       pinentry-qt4 [OPTION...]

DESCRIPTION

       pinentry-qt4 is a program that allows for secure entry of PINs or pass phrases.	That means it tries to take care that the entered informa-
       tion 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 soft-
       ware.

       pinentry-qt implements a PIN entry dialog using the Qt 4 tool kit, so it is especially suitable for users of KDE 4.  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-qt4 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-qt4; 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-qt4).

       --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-qt4.	They are required because pinentry-qt4 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-qt4 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.

NAME

       gpg-preset-passphrase - Put a passphrase into gpg-agent's cache

SYNOPSIS

       gpg-preset-passphrase [options] [command] cache-id

DESCRIPTION

       The  gpg-preset-passphrase  is a utility to seed the internal cache of a running gpg-agent with passphrases.  It is mainly useful for unat-
       tended machines, where the usual pinentry tool may not be used and the passphrases for the to be used keys are given at machine startup.

       Passphrases set with this utility don't expire unless the --forget option is used to explicitly clear them from the cache --- or  gpg-agent
       is  either  restarted  or  reloaded (by sending a SIGHUP to it).  It is necessary to allow this passphrase presetting by starting gpg-agent
       with the --allow-preset-passphrase.

       gpg-preset-passphrase is invoked this way:

	 gpg-preset-passphrase [options] [command] cacheid

       cacheid is either a 40 character keygrip of hexadecimal characters identifying the key for which the passphrase should be set  or  cleared.
       The keygrip is listed along with the key when running the command: gpgsm --dump-secret-keys.  Alternatively an arbitrary string may be used
       to identify a passphrase; it is suggested that such a string is prefixed with the name of the application (e.g foo:12346).

       One of the following command options must be given:

       --preset
	      Preset a passphrase. This is what you usually will use. gpg-preset-passphrase will then read the passphrase from stdin.

       --forget
	      Flush the passphrase for the given cache ID from the cache.

	      The following additional options may be used:

       -v

       --verbose
	      Output additional information while running.

       -P string

       --passphrase string
	      Instead of reading the passphrase from stdin, use the supplied string as passphrase.  Note that this makes  the  passphrase  visible
	      for other users.

       The full documentation for this tool is maintained as a Texinfo manual.	If GnuPG and the info program are properly installed at your site,
       the command

	 info gnupg

       should give you access to the complete manual including a menu structure and an index.
