TSS_RESULT Tspi_TPM_OwnerGetSRKPubKey(TSS_HTPM hTPM,
                                      UINT32*  pulPubKeyLength,

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.

hTPM

The hTPM parameter is used to specify the handle of the TPM object.

pulPubKeyLength

The pulPubKeyLength parameter is the length (in bytes) of the prgbPubKey parameter.

prgbPubKey

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)

Tspi_TPM_OwnerGetSRKPubKey conforms to the Trusted Computing Group Software Specification version 1.2
