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
