[zeromq-dev] Zmq Security for the C# wrapper

[Robert Pickering]

Yes, you're right, I don't think there's been significant renaming, I
think I'm getting confused between the names used in the C++ libzmq and
the names used in the blog post which are the high-level C binding czmq. 

Now I understand this, it makes the job easier. For example to apply a
certificate to a socket I just need to find out what zcert_apply and
zsocket_set_curve_server do and expose the equivalent from in the C#
api.

Thanks,
Rob
