The BCryptDestroyHash function destroys a hash or Message Authentication Code (MAC) object.
NTSTATUS BCryptDestroyHash( BCRYPT_HASH_HANDLE hHash );
The handle of the hash or MAC object to destroy. This handle is obtained by using the BCryptCreateHash function.
Returns a status code that indicates the success or failure of the function.
Possible return codes include, but are not limited to, the following.
||The function was successful.|
||The algorithm handle in the hHash parameter is not valid.|
Depending on what processor modes a provider supports, BCryptDestroyHash 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 hHash parameter must be derived from an algorithm handle returned by a provider that was opened by using the BCRYPT_PROV_DISPATCH flag.
To call this function in kernel mode, use Cng.lib, which is part of the Driver Development Kit (DDK). Windows Server 2008 and Windows Vista: To call this function in kernel mode, use Ksecdd.lib.
