Hi, > ... You should also take into account how crucial your data is. If it's nuclear launch codes I would say that you can't get enough security. Howver if it's an admin system for Bobs local grocery store, then as "Phpster" suggested, a salted hash may well be enough. For example, you could use this: <?php $hash = md5($password . 'salt - bhuyfuyftyfctujvikhgvbhjiftye5645rt68ty97tgifyvcu6yt7d'); ?> -- Richard Heyes HTML5 Graphing for FF, Chrome, Opera and Safari: http://www.rgraph.org (Updated December 20th) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
