Can i use Jzmq 3.1.0 to develop ZMTP 3.0 CurveZMQ mechanism

[RamakrishnaAddanki]

I am currently working on ZMTP3.0 CurveZMQ mechanism using jzmq libraries.so,i am having doubt that can i use jzmq-3.1.0 jar which is in maven central to build that security mechanism in my application like using ZAP for Ldap authentication kind of things. or i need any new jar (like next release jars for that )

I'd say its best to check out from master and install packages locally until we have a new maven release.

416 describes how to do this.

oh ok thanks for the reply. But problem is that i need official bindings (maven repo jar) to build that security on my platform bcoz platform is in distributed setup.my confusion is that jzmq3.1.0.jar also contains ZAuth and ZContext classes.so,is there any problem with that to implement security.have you got it ?

[msteinhoff]

When you talk about "official", does that mean some sort of policy within your organization that only allows jar files from maven central? Because this git repository is the official source and so are the local build artifacts that you create when you clone and build master as-is.

Do you want to make changes to the CurveZMQ mechanism or do you want to use the mechanism in your code? It seems that ZAuth, the class that implements the Java ZAP actor, currently does not handle the Curve mechanism, so I guess you want to make changes to that class. The zauth implementation from czmq and the RFC specs for ZAP and CurveZMQ should provide you with a good starting point.

Thank you very much for your reply.I want to use CurveZMQ mechanism in my code to make zeromq connections secure for that i need to write code in java; and also i need to use LDAP via ZAP as an authenticator to handle the client request to zeromq server.so is this possible with old (jzmq-3.1.0.jar) or can i have to use the new master and build it. By using this master can i able to use curveZMQ mechanism in my code if not is there any other solution rather than implementing that zauth from czmq...

[msteinhoff]

The ZAuth implementation in jzmq currently does not implement the CURVE mechanism at all. The zauth implementation in czmq works with a directory-based keystore.

For an LDAP backend you would have to create your own ZAuth actor anyway.

[RamakrishnaAddanki]

ok so with this master also i can't use curvezmq mechanism in my code right.we need to wait some more time for that...

[msteinhoff]

Correct, but feel free to send a PR to implement this feature.

See C4.1 for more info about how to participate in jzmq development.

@RamakrishnaAddanki If you don't plan to work on jzmq, could you please close the issue?

[RamakrishnaAddanki]

I am planning to work on JZMQ but it takes time i will get back ... Thank you for your support
