* This is passed to the ZAP handler in the 'domain' field * If not set, or empty, then NULL security does not call the ZAP handler * This resolves the phantom ZAP request syndrome seen with sockets where security was never intended (e.g. in test cases) * This means if you install a ZAP handler, it will not get any requests for new connections until you take some explicit action, which can be setting a username/password for PLAIN, a key for CURVE, or the domain for NULL.
ZeroMQ
Welcome
The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
