ZeroTier SDK (libzt, libztcore)

Library edition of ZeroTier

---

The ZeroTier SDK is composed of two libraries: libztcore which is the platform-agnostic network hypervisor, and libzt which is the network hypervisor paired with a userspace network stack. libzt is a superset of libztcore and is distinguished by the fact that it exposes a standard socket API and simple network control API. With these libraries the stack and virtual link are exclusive to your app and traffic is fully encrypted via the Salsa20 cipher. For a more in-depth discussion on the technical side of ZeroTier, check out our Manual

For a complete example, see test/simple.cpp, and anything in the examples directory. With no error checking, a paraphrased example is as follows:

#include "ZeroTier.h"

void myZeroTierEventCallback(struct zts_callback_msg *msg)
{
    switch (msg->eventCode)
    {
        //
    }
}

int main()
{
    zts_start("yourConfig/key/path", &myZeroTierEventCallback, 9994);
    zts_join(0x0123456789abcdef);
    zts_socket(ZTS_AF_INET, ZTS_SOCK_STREAM, 0);
    zts_connect(fd, (const struct sockaddr *)&addr, sizeof(addr));
    zts_write(fd, "welcome to the machine", 22);
    zts_close(fd);
    zts_stop();
    return 0;
}

Build

Build scripts use a combination of make, and cmake. To retrieve sources for all submodules, patch them, and build all targets (debug and release) for your host machine, issue the following:

make update
make patch
make all

All build targets can be seen by using make list.

Resultant libraries will be placed in lib, test and example programs will be placed in bin.
