Description Alexey Proskuryakov 2014-03-07 15:08:21 PST 
SubtleCrypto algorithms just got exposed on workers.

Probably the most notable part of work here is to make structured clone work with CryptoKeys in workers.

Also from the WG resolution:

---------------------------
The previous blocking issues were:
1) Should we define sync interfaces
2) How do we handle multi-threaded Key access

We resolved point 1 by saying "No"
  - In the future, if we wish to do so, it can be as part of / extension to the Promise interface" (eg: imagine a promise.wait() method)
We resolved point 2 by removing the Key Storage (long ago), allowing Keys to be handled in IDB. 
  - All cryptographic state is handled within the Promise, which isn't transferrable between workers
  - Key tainting is no longer required, by virtue of moving the hashed attributes into key generation, so we don't have synchronization risks there
  - Regardless, by virtue of the Promises() interface, implementations can take their own approach to scheduling the work for promises

Is this already working with the new SubtleCrypto changes?

I think so. However, I will prefer to close this bug when all methods are in place.
