<h1>Snowflake</h1>

<p>
<a href="https://trac.torproject.org/projects/tor/wiki/doc/Snowflake" target="_blank">Snowflake</a>
is a WebRTC pluggable transport for Tor.
</p>

<p>
This page enables you to use your web browser as a proxy to help other
Internet users in censored places.
When you click yes, your browser will act as a
censorship circumvention proxy
as long as you are viewing a page with the snowflake badge.
</p>

<div id='options'>

<noscript>
<hr/>
Snowflake proxy requires javascript.
<br/>
To volunteer as a proxy, please enable javascript.
</noscript>

<div id='buttons' style='display:none'>
<p>
Do you want your browser to act as a proxy?
</p>

<p>
<button onclick="enableSnowflake()">
  Yes
</button>
<button onclick="disableSnowflake()">
  No
</button>
</p>
<div id="snowflake-status"></div>
</div>

<div id='cookies-disabled' style='display:none'>
<hr/>
<p>
Your browser has cookies disabled. You will need to enable them in order
to set Snowflake preferences.
</p>
</div>

</div>

<p>
Minimum functionality has been achieved, and it is possible
to bootstrap a Tor client to 100% using Snowflake, and the
browsing experience using this PT is reasonable enough.
</p>

<p>
However, Snowflake is also under active development and much work is needed.
<br/>
It is not yet stable or audited, probably has many issues,
and should not yet be relied upon!!
</p>

See
<a href="https://trac.torproject.org/projects/tor/wiki/doc/Snowflake"
target="_blank">
here</a> for more information.

<hr>

<p>
It is now possible to embed the Snowflake badge on any website:
</p>

<textarea readonly>
&lt;iframe src="https://snowflake.torproject.org/embed.html" width="88" height="16" frameborder="0" scrolling="no"&gt;&lt;/iframe&gt;
</textarea>

<p>
Which looks like this:
</p>
<iframe src="embed.html" width="88" height="16" frameborder="0" scrolling="no"></iframe>

<p>
If it animates, then congratulations -- you are currently acting as a Tor bridge.
