TSS_RESULT Tspi_Context_LoadKeyByBlob(TSS_HCONTEXT hContext, TSS_HKEY hUnwrappingKey,
UINT32 ulBlobLength, BYTE* rgbBlobData,
TSS_HKEY* phKey);
DESCRIPTIONTspi_Context_LoadKeyByBlob creates a key based on the information got‐
ten by the key blob. It then loads the key into the TPM, which unwraps
the key blob by using the key associated with hUnwrappingKey. The key
blob addressed by hUnwrappingKey must have been already loaded into the
TPM. This function returns a handle to the created key object.
PARAMETERS
hContext
The hContext parameter is the handle of the context object.
hUnwrappingKey
The hUnwrappingKey parameter is the handle of the key object which
should be used to unwrap the key information associated with rgbBlobDa‐
ta.
rgbBlobData
The rgbBlobData parameter is the wrapped key to load.
phKey
The phKey parameter receives the handle of the key object representing
the loaded key.
RETURN CODESTspi_Context_LoadKeyByBlob 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_INTERNAL_ERROR
An internal SW error has been detected.
TSS_E_BAD_PARAMETER
One or more parameters is bad.
