kwalletcli_getpin — command line interface to pinentry
kwalletcli_getpin [-q] [-b | -m | -p prompt] [-E | -e errortext] [-N NoText] [-t desctext] [-Y YesText]
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.
The kwalletcli_getpin utility exits 0 on success, 1 if the passphrase input was cancelled by the user, or >1 if an error occurred. Confirmation (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.
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”
kwalletcli_getpin was written by mirabilos <email@example.com> mostly for tarent solutions GmbH.
Some newer pinentry features, such as three-button operation or setting the window title, are not supported yet.
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.
