  _Inout_  BCRYPT_KEY_HANDLE hKey
);

Parameters

hKey [in, out]

The handle of the key to destroy.

Possible return codes include, but are not limited to, the following.

Return codeDescription
STATUS_SUCCESS

The function was successful.

STATUS_INVALID_HANDLE

The key handle in the hKey parameter is not valid.

 

Remarks

Depending on what processor modes a provider supports, BCryptDestroyKey can be called either from user mode or kernel mode. Kernel mode callers can execute either at PASSIVE_LEVEL IRQL or DISPATCH_LEVEL IRQL. If the current IRQL level is DISPATCH_LEVEL, the handle provided in the hKey parameter must be derived from an algorithm handle returned by a provider that was opened with the BCRYPT_PROV_DISPATCH flag.

To call this function in kernel mode, use Cng.lib, which is part of the Driver Development Kit (DDK). For more information, see WDK and Developer Tools.

Windows Server 2008 and Windows Vista:  To call this function in kernel mode, use Ksecdd.lib.
