/** The CardCreateContainerEx function creates a new key container that the
container index identifies and the bContainerIndex parameter specifies. The function
associates the key container with the PIN that the PinId parameter specified.
This function is useful if the card-edge does not allow for changing the key attributes
after the key container is created. This function replaces the need to call
CardSetContainerProperty to set the CCP_PIN_IDENTIFIER property CardCreateContainer
is called.
The caller of this function can provide the key material that the card imports.
This is useful in those situations in which the card either does not support internal
key generation or the caller requests that the key be archived in the card.*/
