Arti is our ongoing project to create a working embeddable Tor client in Rust. It’s nowhere near ready to replace the main Tor implementation in C, but we believe that it’s the future.H7h免费翻墙网

We're working towards our 0.1.0 milestone in early March, where our main current priorities are stabilizing our APIs, and resolving issues that prevent integration. We're planning to do releases every month or so until we get to that milestone.H7h免费翻墙网

Please be aware that every release between now and then will probably break backward compatibility.H7h免费翻墙网

So, what's new in Arti 0.0.3?

Our biggest API change is that we've completely revamped our configuration system to allow changing configuration values from Rust, while the TorClient instance is running.H7h免费翻墙网

In the background, we've also implemented a system for “preemptive circuit construction.” Based on which ports you've used in the recent past, it predicts which circuits you'll likely need in the future, and constructs them in advance to lower your circuit latency.H7h免费翻墙网

There are also a bunch of smaller features, bugfixes, and infrastructure improvements; see the changelog for a more complete list.H7h免费翻墙网

And what's next?

Between now and March, we're going to be focused on three kinds of improvements:H7h免费翻墙网

• Those that will require API breakage.
• Those based on developer feedback.
• Those that resolve technical debt.

We'll try to do our next release around the start of February. It might have a new error system, support for bootstrap reporting, easier setup, and more!H7h免费翻墙网

Here's how to try it out

We rely on users and volunteers to find problems in our software and suggest directions for its improvement. Although Arti isn't yet ready for production use, it should work fine as a SOCKS proxy (if you're willing to compile from source) and as an embeddable library (if you don't mind a little API instability).H7h免费翻墙网

Assuming you've installed Arti (with cargo install arti, or directly from a cloned repository), you can use it to start a simple SOCKS proxy for making connections via Tor with:H7h免费翻墙网

$ arti proxy -p 9150

and use more or less as you would use the C Tor implementation!H7h免费翻墙网

(It doesn't support onion services yet. If compilation doesn't work, make sure you have development files for libsqlite installed on your platform.)H7h免费翻墙网

For more information, check out the README file. (For now, it assumes that you're comfortable building Rust programs from the command line). Our CONTRIBUTING file has more information on installing development tools, and on using Arti inside of Tor Browser. (If you want to try that, please be aware that Arti doesn't support onion services yet.)H7h免费翻墙网

When you find bugs, please report them on our bugtracker. You can request an account or report a bug anonymously.H7h免费翻墙网

And if this documentation doesn't make sense, please ask questions! The questions you ask today might help improve the documentation tomorrow.H7h免费翻墙网

Call for comments—Urgent!

We need feedback on our APIs. Sure, we think we're making them more complete and ergonomic… but it's the users' opinion that matters!H7h免费翻墙网

Here are some ideas of how you can help:H7h免费翻墙网

1. You can read over the high-level APIs for the arti-client crate, and look for places where the documentation could be more clear, or where the API is ugly or hard to work with.H7h免费翻墙网

2. Try writing more code with this API: what do you wish you could do with Tor in Rust? Give it a try! Does this API make it possible? Is any part of it harder than necessary? (If you want, maybe clean up your code and contribute it as an example?)H7h免费翻墙网
