Looks great! Inching closer to complete WebCrypto!

Please confirm the iso-sim build failure is unrelated to your patch before landing.

I wonder if these should have been namespaced as "WebCore::crypto:: ..."

Excellent!

I wish these passed. Do we have a radar to deal with this? Or a bug on W3C to fix?

Thanks Brent for r+ my patch.

I have filed <rdar://problem/31618371> to replace all these customized DER implementations with an Apple platforms' library. Therefore, I don't think we need a namespace for these helper functions since they are not supposed to be used outside Crypto codes and to be used anymore.

We have a bug to keep track the addition of P-521: Bug 169231. We should support P-521 if we could, but it is not an urgent need.
