#include <tss/tspi.h>
TSS_RESULT Tspi_TPM_OwnerGetSRKPubKey(TSS_HTPM hTPM,
UINT32* pulPubKeyLength,
BYTE** prgbPubKey);
Tspi_TPM_OwnerGetSRKPubKey returns the public key of the key object using
owner authorization. This can only be used on 1.2 TPMs, and only to return the
public key of the SRK.
The hTPM parameter is used to specify the handle of the TPM object.
The pulPubKeyLength parameter is the length (in bytes) of the prgbPubKey
parameter.
The prgbPubKey parameter is the pointer to the memory block containing
the public key blob retrieved for the key object referenced by hKey.
Tspi_TPM_OwnerGetSRKPubKey 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_BAD_PARAMETER
- One or more parameters is bad.
- TSS_E_INTERNAL_ERROR
- An internal SW error has been detected.
- TSS_E_TPM_UNSUPPORTED
- The TPM is not version 1.2 or later - (Note: still unimplemented)
