Build Status

libpsl - C library to handle the Public Suffix List

A "public suffix" is a domain name under which Internet users can directly register own names.

Browsers and other web clients can use it to

  • avoid privacy-leaking "supercookies"
  • avoid privacy-leaking "super domain" certificates (see post from Jeffry Walton)
  • domain highlighting parts of the domain in a user interface
  • sorting domain lists by site

Libpsl...

  • has built-in PSL data for fast access (DAWG/DAFSA reduces size from 180kB to ~32kB)
  • allows to load PSL data from files
  • checks if a given domain is a "public suffix"
  • provides immediate cookie domain verification
  • finds the longest public part of a given domain
  • finds the shortest private part of a given domain
  • works with international domains (UTF-8 and IDNA2008 Punycode)
  • is thread-safe
  • handles IDNA2008 UTS#46 (libicu is used by psl2c if installed)

The DAFSA code has been taken from Chromium Project.

API Documentation

You find the current API documentation here.

Quick API example

#include <stdio.h>
#include <libpsl.h>

int main(int argc, char **argv)
{
	const char *domain = "www.example.com";
	const char *cookie_domain = ".com";
	const psl_ctx_t *psl = psl_builtin();
	int is_public, is_acceptable;

	is_public = psl_is_public_suffix(psl, domain);
	printf("%s %s a public suffix.\n", domain, is_public ? "is" : "is not");

	is_acceptable = psl_is_cookie_domain_acceptable(psl, domain, cookie_domain);
	printf("cookie domain '%s' %s acceptable for domain '%s'.\n",
		cookie_domain, is_acceptable ? "is" : "is not", domain);

	return 0;
}

Command Line Tool

Libpsl comes with a tool 'psl' that gives you access to most of the library API via command line.

$ psl --help

prints the usage.
