RE: Key wrap/unwrap/import/export open issue

Thanks Mark for this proposal, which makes your request crystal clear.
We will allocate some time during the next call in 2 weeks, to collect feedbacks from editors and have your proposal integrated in the next public working draft, as it was supposed to.
Regards,
Virginie

Subject: Key wrap/unwrap/import/export open issue

All,

As discussed on a recent call, the key wrap/unwrap support in the latest Working Draft differs from the original proposal (http://www.w3.org/2012/webcrypto/wiki/KeyWrap_Proposal) in two important ways. First in leaving key wrap format to the JS code and second in not defining and mapping JWK attributes for the WebCrypto Key attributes (extractable and usages).

The first point is a clear improvement over the original proposal (IMO).

This second point means we do not have support for unwrapping non-extractable keys (and maintaining that property) in the core draft*. This is properly addressed in the import/export sections. which remain empty (no changes to the wrap/unwrap text are necessary).

The group previously agreed that the original proposal should be included in the draft. I've described the issue in more detail and extracted the relevant parts of the original proposal here: http://www.w3.org/2012/webcrypto/wiki/KeyWrap_Notes_July

* i.e. without appealing to special behaviours attached to pre-provisioned keys out-of-band.
