note 50227 added to function.microtime

md5 time stamps can be further hardened by appending a "secret predefined key" (i.e, one that is stored in a hardened position ... a sort of poor man's bi-directional encryption key) after the timestamp, before passed into the md5 function. a 40-characters long key can seriously hinder the brute force attack described above. Wouldn't use this method for anything really important though ... unless backed up by more layers for defense. ---- Manual Page -- http://www.php.net/manual/en/function.microtime.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50227 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50227&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50227&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50227&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50227&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50227&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50227&report=yes Search -- http://master.php.net/manage/user-notes.php
