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

QCA::EventHandler::EventHandler ( QObject parent = nullptr)

Constructor.

Parameters
parentthe parent object for this object

Member Function Documentation

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
idthe identification number for the event
contextinformation about the type of response required
Examples:
eventhandlerdemo.cpp, and keyloader.cpp.
void QCA::EventHandler::reject ( int  id)

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

Parameters
idthe id corresponding to the password request
Note
the id parameter is the same as that provided in the eventReady() signal.
Examples:
keyloader.cpp.
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:
keyloader.cpp.
void QCA::EventHandler::submitPassword ( int  id,
const SecureArray password 
)

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

Parameters
idthe id corresponding to the password request
passwordthe user-provided password, passphrase or PIN.
Note
the id parameter is the same as that provided in the eventReady() signal.
Examples:
keyloader.cpp.
void QCA::EventHandler::tokenOkay ( int  id)

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

Parameters
idthe id corresponding to the password request
Note
the id parameter is the same as that provided in the eventReady() signal.
