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.

The hEndorsementPubKey parameter is the handle to the object representing the TPM's endorsement public
key. This key is required for encrypting the secret of the SRK and the TPM owner secret. If NULL, the TSP
