Tspi_TPM_ClearOwner - clear TPM ownership
TSS_RESULT Tspi_TPM_ClearOwner(TSS_HTPM hTPM, TSS_BOOL fForcedClear);
Tspi_TPM_ClearOwner wipes the TPM of everything but its endorsement
key. It will wipe the SRK, so anything locked to the SRK will also
disappear when this command is executed. This is the only way to be
certain that keys are gone, as it is the only way to guarantee that
nothing can keep a copy of the key. You must assert either physical
presence or owner authorization in order to use this command.
The hTPM parameter is used to specify the handle of the TPM object.
The fForcedClear parameter is used to tell whether this command is
being executed with owner authorization or with physical presence. If
FALSE, then TPM owner authorization is used. If TRUE, then physical
presence is required to clear the TPM.
Tspi_TPM_ClearOwner returns TSS_SUCCESS on success, otherwise one of
the following values is returned:
hTPM is not a valid handle.
An internal SW error has been detected.
Tspi_TPM_ClearOwner conforms to the Trusted Computing Group Software
