KeyAlgorithms were recently changed to dictionaries (from interfaces)
and we did not get around to change that yet. Richard Barnes has a patch
almost ready in bug 1037892 [1] though.

We didn't have to change tests to make them work with KeyAlgorithm
dictionaries so that change would not break existing code. We would
probably aim to land it before enabling WebCrypto by default anyway.

Yeah, I agree that the chances of content code breaking because of this is minimal.

Other parts we're missing is import/export for some formats (e.g. PKCS8
for ECDH/DH) and we're missing a few algorithms completely. We only need
more time to implement those but that wouldn't break any existing code
either.

Sounds good!

Thanks!

As of September we intend to enable the WebCrypto API by default on all
platforms. It has been developed behind the dom.webcrypto.enabled
preference.

Tracking bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=865789

Spec:
https://dvcs.w3.org/hg/webcrypto-api/raw-file/tip/spec/Overview.html
(A CR is planned soon, only smaller changes to the spec lately.)

Reasoning:
The implementation of the WebCrypto API has made lots of progress in
Firefox 33+34. We added most of the basic functionality and algorithms,
and should be mostly spec compliant.

Chromium has had the WebCrypto API enabled by default since Crome 37,
which was released in late June 2014. Their implementation supports a
subset of the algorithms that we do, and has roughly the same level of
spec compliance. We expect the two implementations to be mostly
interoperable as-is, with some fine points being ironed out as the spec
is finalized.

We thus propose to enable the WebCrypto API by default for all platforms
to get some more feedback from developers and give them the opportunity
to use new functionality.
