typedef struct D3D11_KEY_EXCHANGE_HW_PROTECTION_INPUT_DATA {

Members

PrivateDataSize

The size of the private data reserved for IHV usage. This size is determined from the pPrivateInputSize parameter returned by the ID3D11VideoDevice1::GetCryptoSessionPrivateDataSize function.

HWProtectionDataSize

The size of the DRM command data.

pbInput

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.
