With different password hashing methods supported on different systems and with the need to generate salts with your own PHP code in order to use the more advanced / more secure methods, it takes special knowledge to use crypt() optimally, producing strong password hashes. Other message digest / hashing functions supported by PHP, such as md5() and sha1(), are really no good for password hashing if used naively, resulting in hashes which may be brute-forced at rates much higher than those possible for hashes produced by crypt(). I have implemented a PHP password hashing framework (in PHP, tested with all of PHP 3, 4, and 5) which hides the complexity from your PHP applications (no need for you to worry about salts, etc.), yet does things in almost the best way possible given the constraints of the available functions. The homepage for the framework is: http://www.openwall.com/phpass/ I have placed this code in the public domain, so there are no copyrights or licensing restrictions to worry about. P.S. I have 10 years of experience in password (in)security and I've developed several other password security tools and libraries. So most people can feel confident they're getting this done better by using my framework than they could have done it on their own. ---- Manual Page -- http://www.php.net/manual/en/function.crypt.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60056 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60056&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60056&report=yes Search -- http://master.php.net/manage/user-notes.php
