note 98418 added to function.md5

Here is an example of a MD5 password generator and authenticator. It uses a random salt (chosen from 4, and appends the salt id to the end of the hash). <?php function generateEncryptedPassword($plain) { $s = rand(1,5); $salt = findSalt($s); $encrypted = md5($salt . $plain).':'.$s; return $encrypted; } function authEncryptedPassword($plain,$encrypted) { $temp = explode(':',$encrypted); if(sizeof($temp)==2) { $salt = findSalt($temp[1]); if(md5($salt.$plain)==$temp[0]) { return true; } else { return false; } } else { return false; } } function findSalt($s) { switch($s) { case '1': $salt = '3b0c06d1aa30703fc3bbb3375ec7aee0'; // random hash break; case '2': $salt = '4a6898d364488a8a70bc3a0de6fe9727'; // random hash break; case '4': $salt = 'a9cdebe2bfdca7a0da9a119a4c923a5d'; // random hash break; case '5': $salt = '5f2fe5e261d983a403de38813693e78e'; // random hash break; } return $salt; } ?> ---- Server IP: 208.69.120.55 Probable Submitter: 74.7.52.30 ---- Manual Page -- http://www.php.net/manual/en/function.md5.php Edit -- https://master.php.net/note/edit/98418 Del: integrated -- https://master.php.net/note/delete/98418/integrated Del: useless -- https://master.php.net/note/delete/98418/useless Del: bad code -- https://master.php.net/note/delete/98418/bad+code Del: spam -- https://master.php.net/note/delete/98418/spam Del: non-english -- https://master.php.net/note/delete/98418/non-english Del: in docs -- https://master.php.net/note/delete/98418/in+docs Del: other reasons-- https://master.php.net/note/delete/98418 Reject -- https://master.php.net/note/reject/98418 Search -- https://master.php.net/manage/user-notes.php
