note 49190 added to function.md5

An earlier poster suggested using md5 multiple times and strrev. I cannot stress enough that this is an incredibly bad idea: when you md5 a md5 hash you're vastly increasing the chance of a collision. The only possible security here is through obscurity -- and that's no security at all. If you're worried about md5's collisions, try looking at the sha1 function and/or enforcing password restrictions on your system ---- Manual Page -- http://www.php.net/manual/en/function.md5.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+49190 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+49190&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+49190&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+49190&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+49190&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+49190&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+49190&report=yes Search -- http://master.php.net/manage/user-notes.php
