You cannot do a Reverse MD5!!, and what would be the point of using it if it was reversable. Little Note: The only way at the moment is to brute force the hash. That means to calculate all the possible combinations of bytes, and MD5 them. If the hash matches, you've found what you've been looking for. But that takes a lot of time, let's say at the capacity of today's machines some 10000 years. That means nearly impossible. So don't try to make it. -- http://www.php.net/manual/en/function.md5.php http://master.php.net/manage/user-notes.php?action=edit+24128 http://master.php.net/manage/user-notes.php?action=delete+24128 http://master.php.net/manage/user-notes.php?action=reject+24128
