* We start by creating a primary key (Esys_CreatePrimary).

* This key will be loaded and the unseal command (Esys_Unseal) will be used
* to retrieve the sealed data.
*
* Tested ESYS commands:
* - Esys_Create() (M)
* - Esys_CreatePrimary() (M)
* - Esys_FlushContext() (M)
* - Esys_Load() (M)
* - Esys_Unseal() (M)
