Tor.rb: Onion Routing for Ruby

This is a Ruby library for interacting with the Tor anonymity network.

• http://github.com/bendiken/tor-ruby

Features

• Supports checking whether Tor is installed in the user's current PATH, and if it is, returning the version number.
• Supports parsing Tor configuration files and looking up the values of particular options.
• Supports querying and controlling a locally-running Tor process using the Tor Control Protocol (TC) over a socket connection.
• Supports querying the Tor DNS Exit List (DNSEL) to determine whether a particular host is a Tor exit node or not.
• Compatible with Ruby 1.8.7+, Ruby 1.9.x, and JRuby 1.4/1.5.

Examples

require 'rubygems'
require 'tor'

Checking whether Tor is installed and which version it is

Tor.available?                                     #=> true
Tor.version                                        #=> "0.2.1.25"

Parsing the Tor configuration file (1)

torrc = Tor::Config.load("/etc/tor/torrc")

Parsing the Tor configuration file (2)

Tor::Config.open("/etc/tor/torrc") do |torrc|
  puts "Tor SOCKS port: #{torrc['SOCKSPort']}"
  puts "Tor control port: #{torrc['ControlPort']}"
  puts "Tor exit policy:"
  torrc.each('ExitPolicy') do |key, value|
    puts "  #{value}"
  end
end

Communicating with a running Tor process

Tor::Controller.connect(:port => 9051) do |tor|
  puts "Tor version: #{tor.version}"
  puts "Tor config file: #{tor.config_file}"
end

Checking whether a particular host is a Tor exit node

Tor::DNSEL.include?("185.220.101.21")               #=> true
Tor::DNSEL.include?("1.2.3.4")                     #=> false
