Tspi_Context_LoadKeyByBlob(3)
NAME
Tspi_Context_LoadKeyByBlob - load a key into the TPM using the key's
blob.
SYNOPSIS
#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_LoadKeyByBlob(TSS_HCONTEXT hContext, TSS_HKEY hUnwrappingKey, UINT32 ulBlobLength, BYTE* rgbBlobData, TSS_HKEY* phKey);
DESCRIPTION
Tspi_Context_LoadKeyByBlob creates a key based on the information gotten 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 rgbBlobData.
- 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 CODES
Tspi_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.
