Snowflake is a pluggable transport available in Tor Browser to defeat internet
censorship. Like a Tor bridge, a user can access the open internet when even regular
Tor connections are censored. To use Snowflake is as easy as to switch to a new bridge
configuration in Tor Browser.

This system is composed of three components: volunteers running Snowflake proxies, Tor
users that want to connect to the internet, and a broker, that delivers snowflake
proxies to users.

Volunteers willing to help users on censored networks can help by spinning short-lived
proxies on their regular browsers. Check, how can I use Snowflake?

Snowflake uses the highly effective domain fronting technique to make a connection to
one of the thousands of snowflake proxies run by volunteers. These proxies are
lightweight, ephemeral, and easy to run, allowing us to scale Snowflake more easily
than previous techniques.

For censored users, if your Snowflake proxy gets blocked, the broker will find a new
proxy for you, automatically.

How to run a Snowflake proxy

Option 1 (addon)
Firstly make sure you have WebRTC enabled. Then you can install this addon for Firefox
or this one for Chrome which will let you become a Snowflake proxy. It can also inform
you about how many people you have helped in the last 24 hours.

Option 2 (web browser)
In a browser where WebRTC is enabled:

Go to https://snowflake.torproject.org/embed and toggle the button to opt in to being
a proxy. You shouldn't close that page if you want to remain a snowflake bridge.

Option 3 (standalone)
There are several ways to setup and run a standalone Go snowflake proxy.

Docker setup

You must first have Docker and docker-compose installed.
We have a Docker image to ease the setup of a snowflake proxy. First download docker-
compose.yml. Then, deploy the proxy by running
docker-compose up -d snowflake-proxy
You should now see the output:
Creating snowflake-proxy ... done
and your proxy is up and running!

Ansible

There is now an ansible role to install a Snowflake proxy on Debian created by Jacobo
N�jera: https://galaxy.ansible.com/nvjacobo/snowflake

Compiling and running from source

First you will need to install and configure Go to build the standalone proxy-go code.
If you are running Ubuntu or Debian, you can install Go by executing apt install
golang. Otherwise visit https://golang.org/dl/. You will need Go 1.13+ to run the
Snowflake proxy.

Clone the source code.
git clone https://git.torproject.org/pluggable-transports/snowflake.git

Build the Snowflake proxy.
go build

Run the Snowflake proxy.
For our fallback proxy-go instances on snowflake-broker, we manage proxy-go instances
using runit. However, a simpler nohup command will also allow you to run an instance
in the background.
nohup ./proxy &

Source code
https://gitweb.torproject.org/pluggable-transports/snowflake.git
The following should result in a 100% bootstrap over WebRTC:
git clone https://git.torproject.org/pluggable-transports/snowflake.git
cd snowflake/client
go get
go build
tor -f torrc

Integration with Tor Browser
Snowflake is included in alpha releases of Tor Browser.
Integration of Snowflake into stable Tor Browser is being tracked at ticket #19001
(closed).
To build from source code, see doc/TorBrowser/Hacking. In the tor-browser-build
directory, make alpha or make testbuild will result in browsers with included
Snowflake.

WebRTC fingerprintability
Notes at Fingerprinting.

Reporting bugs
There are two ways to file a bug report:

1. Request an account at the Tor Project GitLab, then open a new issue in the
Snowflake project.
2. File an anonymous ticket by generating an identifier and logging in with it. Then,
find the Snowflake project in the "List of all projects" and create a new issue.

Please try to be as descriptive as possible with your ticket and if possible include
log messages that will help us reproduce the bug.
