Hello everyone.

Is it possible to relax the requirement to sign the claims set if an
authenticated encryption mode with prior shared secrets is used? Eg.
https://tools.ietf.org/html/draft-madden-jose-ecdh-1pu-02. This would
reduce the size of the request object substantially.

Regards,
George Aristy
