Experimenting with CurveZMQ in different languages

curvezmq_docker_example

Experimenting with CurveZMQ in different languages.

The core question of the experiment is to see, whether different languages can interoperate securely via ZeroMQ.

Build & example output: see master branch in

Libraries

• pyzmq key generation, worker
• pony-zmq server, worker
• go: zmq4 worker
• jeromq worker
• tclzmq worker

Architecture

Deployment

• for simplicity: as a Docker Compose config
• keys generated via a simple python script: generate_certificates.py
• server public key distribution via simple copying into the containers

Communication

• ZeroMQ communication via TCP + CurveZMQ (Stonehouse pattern)
• Requests sent on port 7777, and returned on 7778
• The push socket does task distribution to the workers (Divide and conquer pattern)
• Timeouts are (currently) used to stop the demo after the server sends a finite amount of requests

Pony Server

• Sender actor to send sample requests at regular intervals on port 7777
• Receiver actor to receive responses on port 7778
• Printer actor to serialize printing to console
• Worker actor to test pony-zmq in a round-trip (pulling on port 7777, pushing on port 7778)

Python Worker

• polling with a timeout
• pulling on port 7777, pushing on port 7778

Go Worker

• 7777/7778

Groovy Worker

• preparing dependencies for jzmq failed → using jeromq
• 7777/7778

Tcl Worker

• 7777/7778
