No, CurveZMQ has its own properties. I've described this superficially
here: http://hintjens.com/blog:48

Not directly... The keys that CurveZMQ uses are specific to the
elliptic curve cryptography used.  However you could use your existing
certificates and some (non-ZeroMQ) transport to exchange CurveZMQ
