/** Open a handle to an existing persistent key.
*
* Open a handle to a key which was previously created with
* psa_make_key_persistent() when setting its attributes.
* The handle should eventually be closed with psa_close_key()
* to release associated resources.
* Open a handle to a persistent key. A key is persistent if it was created
* with a lifetime other than #PSA_KEY_LIFETIME_VOLATILE. A persistent key
* always has a nonzero key identifier, set with psa_set_key_id() when
* creating the key. Implementations may provide additional pre-provisioned
* keys with identifiers in the range
* #PSA_KEY_ID_VENDOR_MIN–#PSA_KEY_ID_VENDOR_MAX.
*
* The application must eventually close the handle with psa_close_key()
* to release associated resources. If the application dies without calling
* psa_close_key(), the implementation should perform the equivalent of a
* call to psa_close_key().
*
* Implementations may provide additional keys that can be opened with
* psa_open_key(). Such keys have a key identifier in the vendor range,
