8 déc. 2010 - You should have an encryption like md5 or sha512 . You should also have two different salts, a static salt (written by you) and then also a unique salt for that specific password. Some sample code (e.g. registration.php): $unique_salt = hash('md5', microtime()); $password = hash('md5', $_POST['password']. 13 janv. 2013 - You can check using the following function: function isValidMd5($md5 ='') { return preg_match('/^[a-f0-9]{32}$/', $md5); } echo isValidMd5('5d41402abc4b2a76b9719d911017c592');.
