Detailed Description

Interface class for password / passphrase / PIN and token handlers.

This class is used on client side applications to handle the provision of passwords, passphrases and PINs by users, and to indicate that tokens have been correctly inserted.

The concept behind this class is that the library can raise events (typically using PasswordAsker or TokenAsker), which may (or may not) be handled by the application using a handler object (that has-a EventHandler, or possibly is-a EventHandler) that is connected to the eventReady() signal.

Examples

eventhandlerdemo.cpp, and keyloader.cpp.

Constructor & Destructor Documentation

EventHandler()

QCA::EventHandler::EventHandler

(

QObject *

parent = nullptr

)

Constructor.

Parameters

parent

the parent object for this object

Member Function Documentation

eventReady

void QCA::EventHandler::eventReady ( int id, const QCA::Event & context )

signal

signal emitted when an Event requires attention.

You typically need to connect this signal to a compatible slot in your callback handler

Parameters

id	the identification number for the event
context	information about the type of response required

Examples

eventhandlerdemo.cpp, and keyloader.cpp.

reject()

void QCA::EventHandler::reject

(

int

id

)

function to call to indicate that the user declined to provide a password, passphrase, PIN or token.

Parameters

id	the id corresponding to the password request

Note

the id parameter is the same as that provided in the eventReady() signal.

Examples

keyloader.cpp.

start()

void QCA::EventHandler::start

(

)

mandatory function to call after connecting the signal to a slot in your application specific password / passphrase / PIN or token handler

Examples

eventhandlerdemo.cpp, and keyloader.cpp.

submitPassword()

void QCA::EventHandler::submitPassword	(	int	id,
		const SecureArray &	password )

function to call to return the user provided password, passphrase or PIN.

Parameters

id	the id corresponding to the password request
password	the user-provided password, passphrase or PIN.

Note

the id parameter is the same as that provided in the eventReady() signal.

Examples

eventhandlerdemo.cpp, and keyloader.cpp.

tokenOkay()

void QCA::EventHandler::tokenOkay

(

int

id

)

function to call to indicate that the token has been inserted by the user.

Parameters

id	the id corresponding to the password request

Note

the id parameter is the same as that provided in the eventReady() signal.

Examples

eventhandlerdemo.cpp.
