ID3D11VideoDevice::CheckCryptoKeyExchange method
Gets a cryptographic key-exchange mechanism that is supported by the driver.
Syntax
HRESULT CheckCryptoKeyExchange( [in] const GUID *pCryptoType, [in] const GUID *pDecoderProfile, [in] UINT Index, [out] GUID *pKeyExchangeType );
Parameters
- pCryptoType [in]
-
A pointer to a GUID that specifies the type of encryption to be used. The following GUIDs are defined.
Value Meaning - D3D11_CRYPTO_TYPE_AES128_CTR
128-bit Advanced Encryption Standard CTR mode (AES-CTR) block cipher.
- pDecoderProfile [in]
-
A pointer to a GUID that specifies the decoding profile. To get profiles that the driver supports, call ID3D11VideoDevice::GetVideoDecoderProfile. If decoding will not be used, set this parameter to NULL.
- Index [in]
-
The zero-based index of the key-exchange type. The driver reports the number of types in the KeyExchangeTypeCount member of the D3D11_VIDEO_CONTENT_PROTECTION_CAPS structure.
- pKeyExchangeType [out]
-
Receives a GUID that identifies the type of key exchange.
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
