There are many example JWEs both in the appendices of RFC 7516 at https://tools.ietf.org/html/rfc7516#appendix-A and throughout RFC 7520 https://tools.ietf.org/html/rfc7520. I'd suggest having a look at those. -- Mike -----Original Message----- From: jose [mailto:jose-bounces@ietf.org] On Behalf Of Matt David Sent: Wednesday, July 20, 2016 12:59 AM To: jose@ietf.org Subject: [jose] HTTP Request/Response using JWE with RSAES Hey all, I'm working on a module for Flask that allows it to use JWE as a quick plugin. In my testing, I've run into a situation where I'm using RSAES (RSAES-OAEP, RSAES-1_5) and I want to return a JWS. It seems like there could be 2 ways of going about this, but I don't believe that the RFC addresses it: 1. RSAES one way, CEK-only on the way back 2. RSAES two way, with an EPK included on the originator's JWE sent to the remote end I like #2 myself because it uses a fresh CEK for each part of the request / response. It's possible I'm missing something in the RFC, but I'm still unable to find it after reading through it a few times, especially because EPK is specified only for use with ECDH-ES algorithms.
