+<h1>Security Helper</h1>
+
+<p>The Security Helper file contains security related functions.</p>
+
+
+<h2>Loading this Helper</h2>
+
+<p>This helper is loaded using the following code:</p>
+<code>$this->load->helper('security');</code>
+
+<p>The following functions are available:</p>
+
+
+<h2>xss_clean()</h2>
+
+<p>Provides Cross Site Script Hack filtering. This function is an alias to the the one in the
+<a href="../libraries/input.html">Input class</a>. More info can be found there.</p>
+
+
+<h2>hash()</h2>
+
+<p>Permits you to create SHA1 or MD5 one way hashes suitable for encrypting passwords. Will create SHA1 by default. Examples:</p>
+
+<code>
+$str = hash($str); // SHA1<br />
+<br />
+$str = hash($str, 'md5'); // MD5
+</code>
+
+
+
+
+<h2>strip_image_tags()</h2>
+
+<p>This is a security function that will strip image tags from a string. It leaves the image URL as plain text.</p>
+
+<code>$string = strip_image_tags($string);</code>
+
+
+<h2>encode_php_tags()</h2>
+
+<p>This is a security function that converts PHP tags to entities. Note: If you use the XSS filtering function it does this automatically.</p>
+
+<code>$string = encode_php_tags($string);</code>
