Description

A GP11Object holds a handle to a PKCS11 object such as a key or certificate. Token objects are stored on the token persistently. Others are transient and are called session objects.

Details

GP11Object

typedef struct _GP11Object GP11Object;

Represents a PKCS11 object handle such as a key or certifiacte.


gp11_object_from_handle ()

GP11Object*         gp11_object_from_handle             (GP11Slot *slot,
                                                         CK_OBJECT_HANDLE handle);

Initialize a GP11Object from a raw PKCS11 handle. Normally you would use gp11_session_create_object() or gp11_session_find_objects() to access objects.

slot :

The slot on which this object is present.

handle :

The raw handle of the object.

Returns :

The new GP11Object. You should use g_object_unref() when done with this object.

gp11_objects_from_handle_array ()

GList*              gp11_objects_from_handle_array      (GP11Slot *slot,
                                                         CK_OBJECT_HANDLE_PTR handles,
                                                         CK_ULONG n_handles);

Initialize a list of GP11Object from raw PKCS11 handles. The handles argument must contain contiguous CK_OBJECT_HANDLE handles in an array.

slot :

The slot on which these objects are present.

handles :

The raw object handles.

n_handles :

The number of raw object handles.

Returns :

The list of GP11Object. You should use gp11_list_unref_free() when done with this list.

gp11_object_equal ()

gboolean            gp11_object_equal                   (gconstpointer object1,
                                                         gconstpointer object2);

Checks equality of two objects. Two GP11Object objects can point to the same underlying PKCS11 object.

object1 :

A pointer to the first GP11Object

object2 :

A pointer to the second GP11Object

Returns :

TRUE if object1 and object2 are equal. FALSE if either is not a GP11Object.

gp11_object_hash ()

guint               gp11_object_hash                    (gconstpointer object);

Create a hash value for the GP11Object.

This function is intended for easily hashing a GP11Object to add to a GHashTable or similar data structure.

object :

A pointer to a GP11Object

Returns :

An integer that can be used as a hash value, or 0 if invalid.

gp11_object_get_module ()

GP11Module*         gp11_object_get_module              (GP11Object *self);

Get the PKCS11 module to which this object belongs.

self :

The object.

Returns :

The module, which should be unreffed after use.

gp11_object_get_slot ()

GP11Slot*           gp11_object_get_slot                (GP11Object *self);

Get the PKCS11 slot to which this object belongs.

self :

The object.

Returns :

The slot, which should be unreffed after use.

gp11_object_get_handle ()

CK_OBJECT_HANDLE    gp11_object_get_handle              (GP11Object *self);

Get the raw PKCS11 handle of a GP11Object.

self :

The object.

Returns :

The raw object handle.

gp11_object_get_session ()

GP11Session*        gp11_object_get_session             (GP11Object *self);

Get the PKCS11 session assigned to make calls on when operating on this object.

This will only return a session if it was set explitly on this object. By default an object will open and close sessions appropriate for its calls.

self :

The object

Returns :

The assigned session, which must be unreffed after use.

gp11_object_set_session ()

void                gp11_object_set_session             (GP11Object *self,

Set the PKCS11 session assigned to make calls on when operating on this object.

It isn't always necessary to assign a session to an object. By default an object will open and close sessions appropriate for its calls.

If you assign a read-only session, then calls on this object that modify the state of the object will probably fail.

self :

The object

session :

The assigned session

Get the specified attributes from the object. The attributes will be cleared of their current values, and new attributes will be stored. The attributes should not be accessed in any way except for referencing and unreferencing them until gp11_object_get_finish() is called.

This call returns immediately and completes asynchronously.

self :

The object to get attributes from.

attrs :

The attributes to get, initialized with their types.

cancellable :

Optional cancellation object, or NULL.

callback :

A callback which is called when the operation completes.

user_data :

Data to be passed to the callback.

Property Details

The "handle" property

  "handle"                   gulong                : Read / Write / Construct Only

The raw PKCS11 handle for this object.


The "module" property

  "module"                   GP11Module*           : Read / Write / Construct Only

The GP11Module that this object belongs to.


The "session" property

  "session"                  GP11Session*          : Read / Write

The PKCS11 session to make calls on when this object needs to perform operations on itself.

If this is NULL then a new session is opened for each operation, such as gp11_object_get(), gp11_object_set() or gp11_object_destroy().


The "slot" property

  "slot"                     GP11Slot*             : Read / Write / Construct Only

The GP11Slot that this object belongs to.

If this is a token object then it will be stored on the token in this slot. If this is a session object, then it belongs to a session opened on this slot.
