Authentication

[Deeptradingfx]

There is a way add authentication from pubsup some sort of custom token or key should i change the numbers for my code ?

define ZMQ_PLAIN_USERNAME 45

-- 83 | #define ZMQ_PLAIN_PASSWORD 46 84 | #define ZMQ_CURVE_SERVER 47 85 | #define ZMQ_CURVE_PUBLICKEY 48

ANY ONE COULD HELP ME HOW TO KEEP THE COMMUNICATION SAFETY TO PERMIT ONLY AUTHORIZED SUBSCRIBERS

You should check ZEROMQ official documentation, which may have authentication related topic.

Yes i did it from python but i couldnt find it on your library can you give a exemplo on the library where to set a new public key please im working on it for about 120 days and i dont know mql very well

Please Mr Ding post a example using curve pupsub

I would like to share how I did the authentication with curve I do not know if this is correct! but did work.

` Print(">>> Generator for keys Public and secret");

string genpub,gensec; Z85::generateKeyPair(genpub,gensec); Print("1) Generated public key: ",genpub); Print("1) Generated private key: ",gensec); `

Server part ` Context context("helloworld");

Socket socket(context,ZMQ_REP); socket.setCurvePublicKey("server publickey "); socket.setCurveSecretKey("server secretkey"); socket.setCurveServer(true); \ needs to come b4 bind or connect socket.bind("tcp://*:5561");`

now the client must have diferente public key and secretkey

`// Prepare our context and socket Context context("helloworld");

Socket socket(context,ZMQ_REQ); socket.setCurvePublicKey("client publickey"); \ new public key
socket.setCurveSecretKey("client secretkey"); \ new secret key socket.setCurveServerKey("Server public key "); \ same server public key socket.connect("tcp://localhost:5561");`

one more thing the client publickey and secrect key could be random but server has to be static

the client could be like that

` string genpub,gensec; Z85::generateKeyPair(genpub,gensec);

// Prepare our context and socket

Context context("helloworld"); Socket socket(context,ZMQ_REQ); socket.setCurvePublicKey(gensec); socket.setCurveSecretKey(genpub);

socket.setCurveServerKey("Server static publickey"); socket.connect("tcp://localhost:5561");`
