Tspi_Context_RegisterKey - register a key in the TSS Persistent Storage database
#include <tss/platform.h> #include <tss/tcpa_defines.h> #include <tss/tcpa_typedef.h> #include <tss/tcpa_struct.h> #include <tss/tss_typedef.h> #include <tss/tss_structs.h> #include <tss/tspi.h> TSS_RESULT Tspi_Context_RegisterKey(TSS_HCONTEXT hContext, TSS_HKEY hKey, TSS_FLAG persistentStorageType, TSS_UUID uuidKey, TSS_FLAG persistentStorageTypeParent, TSS_UUID uuidParentKey);
Tspi_Context_RegisterKey is the API that registers a key with the TSS Persistent Storage database so that it can be loaded as necessary. It also includes all information required for loading the key, as well as informa- tion about its parent key.
hContext The hContext parameter is the handle of the context object. hKey The hKey parameter is the handle of the key object addressing the key to be registered. persistentStorageType The persistentStorageType parameter indicates the persistent storage the key is registered in. uuidKey The uuidKey parameter is the UUID by which the key is registered in persistent storage. persistentStorageTypeParent The persistentStorageTypeParent parameter indicates the persistent storage that the parent key is registered in. uuidParentKey The uuidParentKey parameter is the UUID by which the parent key is registered in persistent storage.
Tspi_Context_RegisterKey returns TSS_SUCCESS on success, otherwise one of the following values is returned: TSS_E_INVALID_HANDLE hContext is not a valid handle. TSS_E_PS_KEY_NOTFOUND The key cannot be found in the persistent storage database. TSS_E_INTERNAL_ERROR An internal SW error has been detected. TSS_E_BAD_PARAMETER One or more parameters is bad.

Once * the key is no longer useful, unregister it from system PS as part * of clean up. */ // Unregister the Key result = Tspi_Context_UnregisterKey(hContext, TSS_PS_TYPE_SYSTEM, migratableSignUUID, &hKey); if (result != TSS_SUCCESS) Error_Path(); // exit, discarding hKey }
