Come for the Proxy, stay for the Tor Bindings

This repository currently contains a Kotlin/Java8 Tor Library supporting

• Tunnelling traffic through Tor using a custom Socket implementation
• Stream isolation
• Bridges and pluggable transports
• Connecting to hidden services
• Hosting of hidden services

This project was originally based on a previous fork of thaliproject/Tor_Onion_Proxy_Library, but deviated significatnly since.

This is essentially a Wrapper around the official Tor releases, pre-packaged for easiy use and convenient integration into Kotlin/Java Projects. As of you, simply add tor.native as dependency to your project (using JitPack):

    <repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
    </repositories>

<dependency>
    <groupId>com.github.bisq-network.netlayer</groupId>
    <artifactId>tor.native</artifactId>
          <version>${netlayer.version}</version>
      </dependency>

This library provides a plain TCP socket which can be used like any other:

    //set default instance, so it can be omitted whenever creating Tor (Server)Sockets
    //This will take some time
    Tor.default = NativeTor(/*Tor installation destination*/ File("tor-demo"))
    TorSocket("www.google.com", 80, streamId = "FOO" /*this one is optional*/) //clear web
    TorSocket("facebookcorewwwi.onion", 443, streamId = "BAR") //hidden service

    //set default instance, so it can be omitted whenever creating Tor (Server)Sockets
    //This will take some time
    Tor.setDefault(new NativeTor(/*Tor installation destination*/ new File("tor-demo")));
    new TorSocket("www.google.com", 80, "FOO");
    new TorSocket("facebookcorewwwi.onion", 443, "BAR");

To use bridges, simply pass the contents of a bridge configuration obtained from https://bridges.torproject.org/ (line-by-line wrapped in a Collection) as second parameter to the constructor of the NativeTor class.

Hidden services can be hosted by creating a torified ServerSocket.

    //create a hidden service in directory 'test' inside the tor installation directory
    HiddenServiceSocket(8080, "test")
    //optionally attack a ready listener to be notified as soon as the service becomes reachable
    hiddenServiceSocket.addReadyListener { socket -> /*your code here*/}

    //create a hidden service in directory 'test' inside the tor installation directory
    HiddenServiceSocket hiddenServiceSocket = new HiddenServiceSocket(8080, "test");
    //it takes some time for a hidden service to be ready, so adding a listener only after creating the HS is not an issue
    hiddenServiceSocket.addReadyListener(socket -> { /*your code here*/ return null});

This library ships the official Tor binaries. To verify their authenticity, simply rebuild the prepackaged Tor binaries (courtesy of cedric walter) and rebuild the tor.native
