Description Author  

This class can be used to generate an hash of string applying MD5 several times.

It takes a given string and applies the MD5 hashing algorithm several times to make it much harder revert to the original string.

MD5 is an hashing algorithm often used to store passwords in a way that can be verified later.

However, security attacks often use dictionaries of MD5 hashes to discover the original passwords.

This class implements of different approach to compute hashes using MD5 that makes it much harder to build MD5 dictionaries. It applies MD5 several times, thus making it more difficult to discover the original passwords.

DOCUMENTATION for metalix class v1.0

1. include the file
	include('metalix.php');

2. initiate the class
	$test = new metalix('mytext');

3.[optional] output
	echo $test;



[recommended]
I recommend you change the default options within the class

change $this->code = '' to any preferred string. (a random hash is best)
   - this is the string used on either side of the md5 during the encryption process

change $this->level = 10 to any number (try less than 25 so as not to crash the server)
   - this is the number of times the metalix class will run

change $this->add = 5 to any number (try less than 25 so as not to crash the server)
   - this is the number of characters that is added to each side of the md5 hash
