The use of binary for CURVE keys is painful; you cannot easily copy these in e.g. email, or use them directly in source code. There are various encoding possibilities. Base16 and Base64 are not optimal. Ascii85 is not safe for source (it generates quotes and escapes). So, I've designed a new Base85 encoding, Z85, which is safe to use in code and elsewhere, and I've modified libzmq to use this where it also uses binary keys (in get/setsockopt). Very simply, if you use a 32-byte value, it's Base256 (binary), and if you use a 40-byte value, it's Base85 (Z85). I've put the Z85 codec into z85_codec.hpp, it's not elegant C++ but it is minimal and it works. Feel free to rewrap as a real class if this annoys you.
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. Building and installation ------------------------- See the INSTALL file included with the distribution. Resources --------- Extensive documentation is provided with the distribution. Refer to doc/zmq.html, or "man zmq" after you have installed 0MQ on your system.
