| <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 one in the | |
| <a href="../libraries/input.html">Input class</a>. More info can be found there.</p> | |
| <h2>dohash()</h2> | |
| <p>Permits you to create SHA1 or MD5 one way hashes suitable for encrypting passwords. Will create SHA1 by default. Examples:</p> | |
| <code> | |
| $str = dohash($str); // SHA1<br /> | |
| <br /> | |
| $str = dohash($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> | |
