I've just noticed the same, and it seems that contrary to what the RFC says "as-server" is never used, and always set to 00: https://github.com/zeromq/libzmq/blob/master/src/stream_engine.cpp#L562 It has been like that since the first time the RFC was implemented. The ZMQ_CURVE_SERVER option is used to decide if a peer will be client or server (by instantiating the corresponding curve class). Does anyone know what was the intention there? -- Kind regards, Luca Boccassi
