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.
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:
Ask for a confirmation (boolean) instead of a passphrase.
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.
Display a message (one-button query) instead of asking.
- -N NoText
Use NoText instead of
Cancelfor 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.
Be more quiet.
- -t desctxt
Set the descriptive text (the input challenge) to desctxt.
- -Y YesText
Use YesText instead of
OKfor 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:
Read password successfully. Boolean question returned Yes/OK.
Boolean question returned No/Cancel.
Wrong command line syntax.
The process reading user input unexpectedly terminated or errored out.
Unexpected result reading from pinentry.
Unable to determine controlling tty, caller must set
Caught SIGHUP, SIGINT, SIGQUIT, SIGTRAP, SIGPIPE, or SIGTERM.
If not set, pass current terminal information to pinentry.
Terminal type of the current tty. Defaults to the value of the environment variable
TERM, or “vt100” if unset.
The current terminal, determined by tty(1) if unset.
Passed to pinentry. Default: “en_US.UTF-8”
Passed to pinentry. Unset by default.
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.
