Re: Updated eme-generic-protocol with JSON version

I am not sure about the specifics, but I agree with the intent. We should have a version of this implementable using clearkey. At a minimum that would mean that decryptionKeyIdentifier would be optional, since clearkey would not use it.

I have never used JWE, JWS or JWK (I prefer ASN.1/DER) so if you have changes to propose for the structure defined that would help. I am reading up on those spec in my spare time. I did spec the message signing to use JWS as best I could.

Those can all be implemented with WebCrypto, so then the new protocol could be prototyped in JS on top of clearkey. Adding the features we need to clearkey would help with interoperability.
