Contains the size of the private data reserved for IHV usage. This size is determined from the pPrivateInputSize member returned by GetCryptoSessionPrivateDataSize.
HWProtectionDataSize
Contains the size of the DRM command data.
pbInput[4]
If PrivateDataSize is greater than 0, pbInput[0] – pbInput[PrivateDataSize - 1] is reserved for IHV use.
pbInput[PrivateDataSize] – pbInput[HWProtectionDataSize + PrivateDataSize - 1] contains the input data for the DRM command. The format and size of the DRM command is defined by the DRM specification.
