TSS_RESULT Tspi_Context_GetKeyByUUID(TSS_HCONTEXT hContext, TSS_FLAG  persistentStorageType,
                                     TSS_UUID     uuidData, TSS_HKEY* phKey);

DESCRIPTION

persistentStorageType

The persistentStorageType parameter indicates the persistent storage the key is registered in.

uuidData

The uuidData parameter is the UUID by which the key is registered in persistent storage.

phKey

The phKey parameter receives the handle of the key object representing the key.

RETURN CODES

Tspi_Context_GetKeyByUUID returns TSS_SUCCESS on success, otherwise one of the following values is returned:

TSS_E_INVALID_HANDLE: hContext is an invalid 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.
