TSS_RESULT Tspi_TPM_CheckMaintenancePubKey(TSS_HTPM        hTPM, TSS_HKEY hMaintenanceKey,
                                           TSS_VALIDATION* pValidationData);


Tspi_TPM_CheckMaintenancePubKey checks the public maintenance key. If hMaintenanceKey is NULL, then pValidationData must not be NULL; the caller has to proof the digest on its own. If hMaintenanceKey is not NULL, then pValidationData must be NULL; the TSS service provider proofs the digest got internally from the TPM. The key information required for proofing the public maintenance key must be set in the key object by Tspi_SetAttribData before this method is called. This function is not yet implemented.



Handle of the TPM object


Handle of the maintenance key object


Validation data structure. [IN] Provide externalData information required to compute the signature. [OUT] On successful completion of the ocmmand, the structure provides a buffer containing the validation data and a buffer containing the data the validation data was computed from.

Return Codes

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


hTPM is not a valid handle.


An internal SW error has been detected.


One or more of the parameters is incorrect.


The command is not implemented.
