*
|
|
* 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 that can be opened with psa_open_key(). Such keys have an application
|
|
* key identifier in the vendor range, as documented in the description of
|
|
* #psa_key_id_t.
|
|
*
|
|
* The application must eventually close the handle with psa_close_key() or
|
|
* psa_destroy_key() to release associated resources. If the application dies
|
|
* without calling one of these functions, the implementation should perform
|
|
* the equivalent of a call to psa_close_key().
|
|
*
|
|
* Some implementations permit an application to open the same key multiple
|
|
* times. If this is successful, each call to psa_open_key() will return a

* different key handle.
