This function retrieves a password or pin. The implementation might want to use a cache or a password file. The default implementation simply asks the user for input. The function GWEN_Gui_SetPasswordStatus() is used to communicate the status of a password. So if this function here uses a password cache then the callback for GWEN_Gui_SetPasswordStatus() should also be implemented.

NOTE: AqBanking uses GWEN_Gui_PasswordMethod_OpticalHHD as methodId for all optical TAN input methods like "chipTAN optisch" and others. To determine which optical method is actually requested see the DB variable "tanMethodId" inside the methodParams parameter. The data to send to the TAN generator can be found in the toplevel variable "challenge".

Parameters

flags	flags, see GWEN_GUI_INPUT_FLAGS_CONFIRM ff.
token	unique identification for the password or pin. This can be used to read the password from a cache or file.
title	title of the input box
text	Text of the box: UTF-8, with both a normal text and a HTML variant of the text in the same string. See text restrictions note above.
buffer	buffer to store the response in. Must have at least room for maxLen bytes
minLen	minimal length of the password (if 0 then there is no low limit)
maxLen	size of the buffer including the trailing NULL character. This means that if you want to ask the user for a PIN of at most 4 characters you need to supply a buffer of at least 5 bytes and provide a 5 as maxLen.
methodId	Id of the pin/password/tan entry.
methodParams	additional parameters for the pin/password/tan entry, content depends on the methodId (my be NULL for simple text input)
guiid	id as returned by GWEN_Gui_ProgressStart or GWEN_Gui_ShowBox)
