ASP.Net machinekey, validationkey, and decryptionkey - key lengths
<p>What are the default key lengths that are generated when leaving the ValidationKey and DecryptionKey at their defaults?   For example:</p>

<pre><code>&lt;machineKey decryptionKey="AutoGenerate,IsolateApps" validationKey="AutoGenerate,IsolateApps" ... /&gt;
</code></pre>

<p>I have not been able to find this documented anywhere on MSDN.
I would like to generate a static machine key and keep it in line with the defaults.</p>
