>Let the clients handle end-to-end encryption with something zk DH/OTR/SMP. ZeroMQ also has its own experimental elliptical-curve encryption protocol now: http://curvezmq.org/ http://curvezmq.org/ They call it experimental, but I've haven't heard anything negative about the implementation from the cryptographers, and elliptical curve crypto is well-established (it's the basis for Bitcoin's key signing, for example). Also, it's closely based on Daniel J. Bernstein's CurveCP.
