......@@ -1121,23 +1191,216 @@ Aborts the use of the key. This method uses a promise to return the result.
**Example**
```js
/* huks.init, huks.update, and huks.finish must be used together.
* If an error occurs in any of them, huks.abort must be called to terminate the use of the key.
*
* The following uses the promise of an RSA 1024-bit key as an example.
