Right, so the binary format is uint32_t/uint64_t, but with the restriction that the maximum value they should contain is INT32_MAX/INT64_MAX.
And a, hopefully, last one: The ZAP RFC specifies that an authentication request contains an identity field, which holds: “The identity, the identity of the originating ZeroMQ socket.”, from the protocol structure I’m guessing that the “originating socket” is the “local” one, that is:
If node A uses a socket with identity Foo to connect to a (server) socket with identity Bar on node B, then the auth request is handled on node B by sending a request with the identity “Bar” to the auth socket, yes?
Similarly, the auth response contains a user id, but I don’t see mention of it’s use anywhere?
