NAME

       Tspi_TPM_TakeOwnership - take ownership of a 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_TPM_TakeOwnership(TSS_HTPM hTPM, TSS_HKEY hKeySRK,
					 TSS_HKEY hEndorsementPubKey);

DESCRIPTION

       Tspi_TPM_TakeOwnership  takes  ownership  of a TPM. Taking ownership is the process of inserting a shared secret into the TPM. The owner of
       the TPM (anyone who knows the shared secret) has the right to perform special operations.

PARAMETERS

   hTPM
       The hTPM parameter is used to specify the handle of the TPM object.

   hKeySRK
       The hKeySRK parameter is the handle to the object representing the TPM's Storage Root Key.

   hEndorsementPubKey
       The hEndorsementPubKey parameter is the handle to the object representing the TPM's endorsement public key. This key is	required  for  en-
       crypting the secret of the SRK and the TPM owner secret. If NULL, the TSP internally queries the TPM for that endorsement public key.

RETURN CODES

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

       TSS_E_INVALID_HANDLE
	      Either the TPM or one of the key handles is not valid.

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

CONFORMING TO

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

NAME

       Tspi_TPM_GetPubEndorsementKey - create a TSS key object from the TPM's public endorsement key

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_TPM_GetPubEndorsementKey(TSS_HTPM	hTPM,		 TSS_BOOL  fOwnerAuthorized,
						TSS_VALIDATION* pValidationData, TSS_HKEY* phEndorsementPubKey);

DESCRIPTION

       Tspi_TPM_GetPubEndorsementKey  This function retrieves the public endorsement key (PubEK) from the TPM and creates a TSS key object for it,
       whose handle is returned in phEndorsementPubKey. Due to the fact that different TPM chips validate the PubEK in different ways, application
       verification of the PubEK (using a non-NULL pValidationData is broken.  Tspi_TPM_GetPubEndorsementKey should be called with a NULL pValida-
       tionData parameter to allow the TSS to verify the PubEK itself.

PARAMETERS

   hTPM
       The hTPM parameter is used to specify the handle of the TPM object.

   fOwnerAuthorized
       If TRUE, the TPM owner secret must be provided to get the public endorsement key.  If FALSE, no TPM owner secret must be  provided  to  get
       the public endorsement key.

   pValidationData
       If  non-NULL,  the  application	should	set  the  pValidationData->rgbExternalData  parameter  to  20  bytes of random data before calling
       Tspi_TPM_GetPubEndorsementKey. On successful completion of the command, the structure will provide buffers containing the  validation  data
       and the buffer the validation data was computed from.

   phEndorsementPubKey
       Receives a handle to a key object representing the TPM's public endorsement key.

RETURN CODES

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

       TSS_E_INVALID_HANDLE
	      hTPM 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.

       TPM_E_DISABLED_CMD
	      Reading of PubEK from TPM has been disabled.

CONFORMING TO

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