Description

Details

WockyAuthAuthDataFunc ()

gboolean            (*WockyAuthAuthDataFunc)            (WockyAuthHandler *handler,
                                                         const GString *data,
                                                         GString **response,
                                                         GError **error);

struct WockyAuthHandlerIface

struct WockyAuthHandlerIface {
    GTypeInterface parent;
    gchar *mechanism;
    gboolean plain;
    WockyAuthInitialResponseFunc initial_response_func;
    WockyAuthAuthDataFunc auth_data_func;
    WockyAuthSuccessFunc success_func;
};

GTypeInterface parent;

The parent interface.

gchar *mechanism;

The AUTH mechanism which this handler responds to challenges for.

gboolean plain;

Whether the mechanism this handler handles sends secrets in plaintext.

WockyAuthInitialResponseFunc initial_response_func;

Called when the initial <auth /> stanza is generated

WockyAuthAuthDataFunc auth_data_func;

Called when any authentication data from the server is received

WockyAuthSuccessFunc success_func;

Called when a <success/> stanza is received.

WockyAuthInitialResponseFunc ()

gboolean            (*WockyAuthInitialResponseFunc)     (WockyAuthHandler *handler,
                                                         GString **initial_data,
                                                         GError **error);

Called when authentication begins, if the mechanism allows a response to an implicit challenge during AUTH initiation (which, in XMPP, corresponds to sending the <auth/> stanza to the server).

The function should return TRUE on success, and optionally set the initial_data to a string if there is initial data to send. On error, it should return FALSE and set error.

handler :

a WockyAuthHandler object

initial_data :

a GString location to fill with the initial data. [out]

error :

an optional location for a GError to fill, or NULL

Returns :

TRUE on success, otherwise FALSE

WockyAuthSuccessFunc ()

gboolean            (*WockyAuthSuccessFunc)             (WockyAuthHandler *handler,
                                                         GError **error);

Called when a <success/> stanza is received during authentication. If no error is returned, then authentication is considered finished. (Typically, an error is only raised if the <success/> stanza was received earlier than expected)

handler :

a WockyAuthHandler object

error :

an optional location for a GError to fill, or NULL

Returns :

TRUE on success, otherwise FALSE

wocky_auth_handler_get_initial_response ()

gboolean            wocky_auth_handler_get_initial_response
                                                        (WockyAuthHandler *handler,
                                                         GString **initial_data,
                                                         GError **error);

Called when authentication begins to fetch the initial data to send to the server in the <auth/> stanza.

If this function returns TRUE, initial_data will be non-NULL if handler provides an initial response, and NULL otherwise.

handler :

a handler for a SASL mechanism

initial_data :

initial data to send to the server, if any. [out][transfer full]

error :

an optional location for a GError to fill, or NULL

Returns :

TRUE on success; FALSE otherwise.

wocky_auth_handler_get_mechanism ()

const gchar *       wocky_auth_handler_get_mechanism    (WockyAuthHandler *handler);

Returns the name of the SASL mechanism handler implements.

handler :

a handler for a SASL mechanism.

Returns :

the name of the SASL mechanism handler implements.

wocky_auth_handler_handle_auth_data ()

gboolean            wocky_auth_handler_handle_auth_data (WockyAuthHandler *handler,
                                                         const GString *data,
                                                         GString **response,
                                                         GError **error);

Asks handler to respond to a <challenge/> stanza or a <success/> with data. On success, handler will put response data into response, Base64-encoding it if appropriate.

handler :

a WockyAuthHandler object

data :

the challenge string

response :

a location to fill with a challenge response in a GString. [out][transfer full]

error :

an optional location for a GError to fill, or NULL

Returns :

TRUE on success, otherwise FALSE

wocky_auth_handler_handle_success ()

gboolean            wocky_auth_handler_handle_success   (WockyAuthHandler *handler,
                                                         GError **error);

Called when a <success/> stanza is received during authentication. If no error is returned, then authentication is considered finished. (Typically, an error is only raised if the <success/> stanza was received earlier than expected)

handler :

a WockyAuthHandler object

error :

an optional location for a GError to fill, or NULL

Returns :

TRUE on success, otherwise FALSE

wocky_auth_handler_is_plain ()

gboolean            wocky_auth_handler_is_plain         (WockyAuthHandler *handler);

Checks whether handler sends secrets in plaintext. This may be used to decide whether to use handler on an insecure XMPP connection.

handler :

a handler for a SASL mechanism.

Returns :

TRUE if handler sends secrets in plaintext.
