Required types for secure messaging are missing about clrzmq4

[metadings]

No, the zauth-like syntactic sugar is currently not in clrzmq4.

Please look into the ZSocket class.
You can use the socket options to run ZeroMQ on a CURVEd socket.
There are bool ZSocket.CurveServer, byte[] ZSocket.CurveSecretKey,
byte[] ZSocket.CurvePublicKey and byte[] ZSocket.CurveServerKey.

Works like a charm. Thanks metadings!

Hi metadings,

I am looking to implement this too, will zauth be in the bindings eventually?

How can you generate new keys to be used and saved?

Sorry if they are stupid questions, I am not that experienced at development.

Thanks

wow hey, the ZAuthentication classes will take some time...

The privateKey of an authentication you get using a random number generator:

var privateKey = new byte[32];
using (var rng = new RNGCryptoServiceProvider()) rng.GetBytes(privateKey);

you could now calculate the publicKey using...

var publicKey = new byte[32];
crypto.box_keypair(publicKey, privateKey);

... if you use some library like jedisct1/libsodium!

Hi Uli,

Thanks for the info, I will look into libsodium, it seems like a very
interesting library.

That should give me enough to get me going.

Unfortunately I'm not confident enough to be able to help with the zauth
work. I have never wrapped a c library in c# and wouldn't now where to
begin.

One other question. Is there anyway to convert a z frame directly to a
byte[]?

Thanks

Dean

Yes, using

frame.Position = 0;
byte[] bytes = (ZFrame)frame.Read();

That's actually a very new method, you need to git pull origin master or just download the zip file.

I am going to post myself a crypto library tweetnacl.c and TweetNaCl.CSharp ... wait some hours!

Could a curve example be added to https://github.com/metadings/zguide please? As someone not that familiar with curve this gives me some good clues to get started, but a hello world example with curve security would help a ton. Thanks!

@rr118 you should open a new issue, I'm going to close this one...
