KWALLETCLI_GETPIN(1)					    BSD General Commands Manual 				      KWALLETCLI_GETPIN(1)

NAME

     kwalletcli_getpin -- command line interface to pinentry

SYNOPSIS

     kwalletcli_getpin [-q] [-b | -m | -p prompt] [-E | -e errortext]
		       [-N NoText] [-t desctext] [-Y YesText]

DESCRIPTION

     The kwalletcli_getpin utility is a shell wrapper speaking to pinentry using the Assuan protocol.  It will ask the user for a passphrase and
     print it, without any trailing newline, to standard output.  There are options for asking a boolean question or displaying a message.

     If PINENTRY is not empty but points to a non-existing or failing programme, pinentry is not called.  Instead, xmessage(1) is used for boolean
     queries and messages if DISPLAY is set; otherwise, kwalletcli_getpin uses simple terminal I/O on GPG_TTY using stty(1) to disable echo of
     terminal input for passphrase queries.

     The options are as follows:

     -b 	 Ask for a confirmation (boolean) instead of a passphrase.

     -E 	 Unset a previously set error text.

     -E errtxt	 Set the error text to errtxt, displaying a dialogue box with a red X icon indicating that this is a retry question.

     -m 	 Display a message (one-button query) instead of asking.

     -N NoText	 Use NoText instead of Cancel for the text of the abort button, if any.

     -p prompt	 Set the small descriptive text shown in front of the input field (``the Prompt'') to prompt.

     -q 	 Be more quiet.

     -t desctxt  Set the descriptive text (the input challenge) to desctxt.

     -Y YesText  Use YesText instead of OK for the text of the confirm button.

     All input and output is assumed to be in UTF-8.

RETURN VALUES

     The kwalletcli_getpin utility exits 0 on success, 1 if the passphrase input was cancelled by the user, or >1 if an error occurred.  Confirma-
     tion (boolean) error codes are 0 for Yes, 1 for No, or >1 if an error occurred.  Messages return >0 if an error occurred, 0 otherwise.

     A summary of the error codes follows:
     0	Read password successfully.  Boolean question returned Yes/OK.
     1	Boolean question returned No/Cancel.
     2	Wrong command line syntax.
     3	The process reading user input unexpectedly terminated or errored out.
     4	Unexpected result reading from pinentry.
     5	Unable to determine controlling tty, caller must set GPG_TTY.
     6	Caught SIGHUP, SIGINT, SIGQUIT, SIGTRAP, SIGPIPE, or SIGTERM.

ENVIRONMENT

     DISPLAY	  If not set, pass current terminal information to pinentry.

     GPG_TERM	  Terminal type of the current tty.  Defaults to the value of the environment variable TERM, or ``vt100'' if unset.

     GPG_TTY	  The current terminal, determined by tty(1) if unset.

     LC_CTYPE	  Passed to pinentry.  Default: ``en_US.UTF-8''

     LC_MESSAGES  Passed to pinentry.  Unset by default.

     PINENTRY	  The pinentry programme to use.  Default: ``pinentry''

AUTHORS

     kwalletcli_getpin was written by Thorsten Glaser <tg@mirbsd.org> mostly for tarent GmbH.

CAVEATS

     Some newer pinentry features, such as three-button operation or setting the window title, are not supported yet.

BUGS

     Some pinentry programmes may not support messages correctly and display them as boolean queries instead.

     Some implementations display labels with the wrong charset.

     Neither of these two problems is an issue in kwalletcli_getpin but a bug of the backend implementation.
