NAME

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

       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  pValidationData
       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.

       Tspi_TPM_GetPubEndorsementKey  conforms  to   the   Trusted   Computing   Group   Software
