The way WebCrypto key usages are mapped to JWK has changed since we implemented it. It used to be a comma separated list in "use" attribute, and now they go into a different attribute, key_ops.
Changes in <https://dvcs.w3.org/hg/webcrypto-api/rev/05819fa07004>.
Created attachment 222759 [details] patch I have this implemented, but the patch breaks tests because of an underlying library issue accidentally uncovered by this change, <rdar://problem/15949992>.
Turns out it's more of a WebCrypto spec issue than a library issue. Tracking that as <https://www.w3.org/Bugs/Public/show_bug.cgi?id=24457>.
