Subject: Platform support for JWA algorithms

I've been doing some investigation into the state of support for the JWA algorithms in common Web development platforms.  The attached table is the data gathered to date.

I'll be leading a discussion based upon this data during our session at IETF 84.  If any of you have more data that I should add, or believe that there are additional columns or rows we should track, please let me know.

Thanks to Roland Hedberg, Axel Nennker, Emmanuel Raviart, Nov Matake, Justin Richer, and Edmund Jay for the data they provided, based upon their implementation experiences.

                                                            -- Mike
