A zauth object takes over authentication for all incoming connections in its context\&.

|
|
This class is deprecated in CZMQ v3; it works together with zctx, zsocket, and other deprecated V2 classes\&. New applications should use the V3 zauth interface, based on zactor, together with the zsock class for sockets\&.
