Could anyone in this fine WG explain (probably again, I missed it the first time) the rational behind the text 'The length of this octet string MUST be the full size of a coordinate for the curve specified in the "crv" parameter.', which is in the definitions of the X and Y Coordinate parameters for EC keys in JWA [1]?
This message last month on the list http://www.ietf.org/mail-archive/web/jose/current/msg03901.html and an off list message indicate that both the jose4j and Nimbus JOSE+JWT implementations aren't following spec on the length of the octet string being the full size of a coordinate for the curve. Which suggests that there maybe potential interoperability problems with certain EC JWKs. I'm just trying to wrap my head around the issue so any help in that would be appreciated.
