Arti Sample Projects

This is a collection of small projects created to help find bugs and documentation gaps in Arti's APIs as a part of Google Summer of Code 2023.

They include:

• A simple download manager utility which downloads a Linux variant of the Tor Browser Bundle over Tor using arti-client and arti-hyper (for the HTTPS request). It makes six connections to concurrently download parts of the Tor Browser Bundle over each connection to speed up transfer rates considerably.

• A DNS resolver a-la dig, which will make a DNS over TCP request to a DNS server over Tor. It helps show how arbitrary bytestreams can be routed over Tor effectively, and includes a toy DNS implementation for this purpose.

• An obfs4 connection checker, which takes in a list of all obfs4 bridges and checks their health, ie, whether they are online or not, as well as delivers updates on their statuses, all through a RESTful API

• A connection checker, which runs on a user's machine to help report whether different ways to connect to the Tor Network work (ie, normal Tor connections, Snowflake Tor connections, obfs4 Tor connections etc.)

• A pt-proxy program that allows you to use obfs4 independently of Tor to obfsucate your own traffic
