		   TCG Software	Stack Developer's Reference

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  en-
       dorsement 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 pValidation-
       Data 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  en-
       dorsement  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->rgbExter-
       nalData	 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 en-
       dorsement 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
