Tspi_Key_CreateMigrationBlob(3) 		     TCG Software Stack Developer's Reference			   Tspi_Key_CreateMigrationBlob(3)

NAME

       Tspi_Key_CreateMigrationBlob - create a key blob suitable for migrating to another TPM.

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_Key_CreateMigrationBlob(TSS_HKEY hKeyToMigrate,		TSS_HKEY hParentKey,
					       UINT32	ulMigTicketLength,	BYTE*	 rgbMigTicket,
					       UINT32*	pulRandomLength,	BYTE**	 prgbRandom,
					       UINT32*	pulMigrationBlobLength, BYTE**	 prgbMigrationBlob);

DESCRIPTION

       Tspi_Key_CreateMigrationBlob  returns a key blob containing an encrypted section, which will be different depending on the migration scheme
       indicated within the migration ticket previously created by the method Tspi_TPM_AuthorizeMigrationTicket().

PARAMETERS

   hKeyToMigrate
       Handle of the key object to migrate.

   hParentKey
       Handle to the parent key related to the key addressed by hKeyToMigrate.

   ulMigTicketLength
       The length (in bytes) of the rgbMigTickey parameter.

   rgbMigTicket
       Pointer to memory containing the migration ticket (migration public key and its authorization digest).

   pulRandomLength
       On successful completion this parameter returns the random data length returned at the parameter prgbRandom.

   prgbRandom
       On successful completion this parameter returns the random data.

   pulMigrationBlobLength
       On successful completion this parameter returns the length of the migration blob data returned at the parameter prgbMigrationBlob.

   prgbMigrationBlob
       On successful completion this parameter returns the migration data blob.

RETURN CODES

       Tspi_Key_CreateMigrationBlob returns TSS_SUCCESS on success, otherwise one of the following values are returned:

       TSS_E_INVALID_HANDLE - Either hKeyToMigrate, hParentKey or rgbMigTicket are invalid parameters.

       TSS_E_BAD_PARAMETER - One of the passed parameters is wrong.

       TSS_E_KEY_NO_MIGRATION_POLICY - No migration policy picked.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

       Tspi_Key_CreateMigrationBlob conforms to the Trusted Computing Group Software Specification version 1.1 Golden

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 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 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.
