libzt

Embed ZeroTier directly into your app

---

ZeroTier makes it easy to securely connect devices, servers, cloud VMs, containers, and apps everywhere and manage them at scale. Now, with libzt you can bake this ability directly into your app or service using your preferred language or framework. We provide a BSD socket-like API to make the integration simple and there's no longer any need for system-wide virtual interfaces. This connection is exclusive to your app.

Example

#include "libzt.h"

char *str = "welcome to the machine"; // test msg 
char *nwid = "c7cd7c9e1b0f52a2";      // network to join
char *path = "zt1";                   // path where this node's keys and configs will be stored
char *ip = "10.8.8.42";               // host on ZeroTier network
int port = 8080;                      // resource's port

struct sockaddr_in addr;
addr.sin_family = AF_INET;
addr.sin_addr.s_addr = inet_addr(ip);
addr.sin_port = hton(port);	

zts_simple_start(path, nwid);
int fd = zts_socket(AF_INET, SOCK_STREAM, 0);
zts_connect(fd, (const struct sockaddr *)addr, sizeof(addr));
zts_write(fd, str, strlen(str));
zts_close(fd);
