The BCryptDestroyHash function destroys a hash or Message Authentication Code (MAC) object.
NTSTATUS BCryptDestroyHash(
BCRYPT_HASH_HANDLE hHash
)
hHash
Type: BCRYPT_HASH_HANDLE
[in, out] The handle of the hash or MAC object to destroy. This handle is obtained by using the BCryptCreateHash function.
Type: NTSTATUS
Returns a status code that indicates the success or failure of the function.
Possible return codes include, but are not limited to, the following.
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The function was successful. |
| STATUS_INVALID_HANDLE | 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_LEVELIRQL 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.
