PFND3D11_1DDI_GETENCRYPTIONBLTKEY callback function (d3d10umddi.h)
Queries the key that is used to decrypt the data returned by the EncryptionBlt(D3D11_1) function.
Syntax
PFND3D11_1DDI_GETENCRYPTIONBLTKEY Pfnd3d111DdiGetencryptionbltkey;
void Pfnd3d111DdiGetencryptionbltkey(
D3D10DDI_HDEVICE hDevice,
D3D11_1DDI_HCRYPTOSESSION hCryptoSession,
UINT KeySize,
VOID *pReadbackKey
)
{...}
Parameters
hDevice
A handle to the display device (graphics context).
hCryptoSession
A handle to the cryptographic session that was created in a call to the driver's CreateCryptoSession function.
KeySize
The size, in bytes, of the encryption key that the pReadBackKey parameter points to.
pReadbackKey
A pointer to a buffer that contains the encryption key.
Return value
None
Remarks
When the GetEncryptionBltKey function is called, the display miniport driver should generate a new encryption key. If the cryptographic session is using the D3DCRYPTOTYPE_AES128_CTR cryptographic type, the driver or graphics adapter should encrypt the data that is referenced by the pReadbackKey parameter by using the session key with the AES-ECB algorithm.
