The spec has changed, WebCrypto HmacKeyParams.length is now in bits, not bytes.
This makes it consistent with other lengths.

Sorry, please ignore the patch at Comment2.
I should not add new error code into DOMCoreExceprion.
I'm new to WebKit.
Would you mind helping me to fix this bug?
I think I should make new ExceptionFile like IDBDatabaseException to handle DATA_ERR.

We already shipped it like this, so we can't just fix it without aligning with the rest of the spec, and removing webkit prefix.
Otherwise, there is no good way for JS code to know what units the length is in.
Thank you for your answering.
Is there plan to remove WebKit prefix?
I don't think that anyone is working on this now.
It may be best to start a parallel implementation under an #if, and enable it when done. There were so many changes in the spec since last year that it should be easier to implement it from scratch than to fix the old implementation.
This bug is fixed by Bug 163718.
