How to encrypt or hide parameters of URL?
<p>Sample URL:</p>

<pre><code>file.php?foo=bar
</code></pre>

<p>index.php will send encrypted variables <code>?foo=bar</code> to <code>file.php</code> and here vars will be decrypted.</p>

<p>Its possible to hide or encrypt vars?</p>

<p>i have form:</p>

<pre><code>&lt;form id="add"&gt;
&lt;input type="text" name="v"/&gt;&lt;br&gt;
&lt;input type="text" name="o1"/&gt;&lt;br&gt;
&lt;input type="text" name="o2"/&gt;&lt;br&gt;
&lt;input type="text" name="o3"/&gt;&lt;br&gt;
&lt;input type="text" name="o4"/&gt;&lt;br&gt;
&lt;input size="1" type="text" name="good"/&gt;
&lt;input id="btn" formaction="add.php" type="submit" value="Go"&gt;
&lt;/form&gt;
</code></pre>
