init() method accepts a void pointer which is the made to point to
    Keys_iterator instance. Keys_iterator instance internal pointer points
    to Key_metadata list. This list holds information about all keys stored
    in the backed end data store of keyring plugin. After call to init()
    please check iterator_ptr.

get_key() method accepts the above iterator_ptr as IN param and then
    fills the passes in key_id and user_id with valid values. This can be
    used to fetch actual key information. Every call to this method will
    change internal pointers to advance to next position, so that the next
    call will fetch the next key.

deinit() method frees all internal pointers along with iterator_ptr.
