TSS_RESULT Tspi_TPM_TakeOwnership(TSS_HTPM hTPM, TSS_HKEY hKeySRK,
TSS_HKEY hEndorsementPubKey);
DESCRIPTIONTspi_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 spe‐
cial 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 represent‐
ing the TPM's endorsement public key. This key is required for encrypt‐
ing the secret of the SRK and the TPM owner secret. If NULL, the TSP
internally queries the TPM for that endorsement public key.
RETURN CODESTspi_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.
