The IHV Extensions DLL calls the Dot11ExtSetUnicastCipherAlgorithm function to enable a unicast cipher algorithm on the wireless LAN (WLAN) adapter.
DWORD APIENTRY Dot11ExtSetUnicastCipherAlgorithm( _In_opt_ HANDLE hDot11SvcHandle, _In_ DWORD dwUnicastCipherAlgo );
- hDot11SvcHandle [in, optional]
The handle used by the operating system to reference the WLAN adapter. This handle value was specified through a previous call to the Dot11ExtIhvInitAdapter IHV Handler function.
- dwUnicastCipherAlgo [in]
A DOT11_CIPHER_ALGORITHM enumerator value that identifies the unicast cipher algorithm.
If the value is within the range of DOT11_CIPHER_ALGO_IHV_START through DOT11_CIPHER_ALGO_IHV_END, the IHV Extensions DLL enables a proprietary cipher algorithm supported by the WLAN adapter.
Otherwise, the DLL is responsible for processing a standard cipher algorithm supported by the operating system. In this situation, the operating system is not involved with any aspect of the cipher algorithm, including key management and replay protection, over a basic service set (BSS) network connection through the WLAN adapter.
Note The value of dwUnicastCipherAlgo must match the value of a cipher algorithm returned by the Native 802.11 miniport driver through queries of OID_DOT11_SUPPORTED_UNICAST_ALGORITHM_PAIR or OID_DOT11_SUPPORTED_MULTICAST_ALGORITHM_PAIR.
If the call succeeds, the function returns ERROR_SUCCESS. Otherwise, it returns an error code defined in Winerror.h.
