xxx_ucenter_members(ucenter的用户表)
ucenter的用户的加密方法如下:
加密密码:md5(md5($password).$salt) $salt为random函数返回的字符串$hash
$salt即是xxx_ucenter_members中的字段salt的值
random函数的代码如下:
<?php
function random($length, $numeric = 0) {
PHP_VERSION < '4.2.0' && mt_srand((double)microtime() * 1000000);
if($numeric) {
$hash = sprintf('%0'.$length.'d', mt_rand(0, pow(10, $length) - 1));
} else {
$hash = '';
$chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz';
$max = strlen($chars) - 1;
for($i = 0; $i < $length; $i++) {
$hash .= $chars[mt_rand(0, $max)];
}
}
return $hash;
exit;
}
?>
看了下uc源码:model/user.php
function add_user($username, $password, $email, $uid = 0, $questionid = '', $answer = '') {
$salt = substr(uniqid(rand()), -6);
$password = md5(md5($password).$salt);
$sqladd = $uid ? "uid='".intval($uid)."'," : '';
$sqladd .= $questionid > 0 ? " secques='".$this->quescrypt($questionid, $answer)."'," : " secques='',";
$this->db->query("INSERT INTO ".UC_DBTABLEPRE."members SET $sqladd username='$username', password='$password', email='$email', regip='".$this->base->onlineip."', regdate='".$this->base->time."', salt='$salt'");
$uid = $this->db->insert_id();
$this->db->query("INSERT INTO ".UC_DBTABLEPRE."memberfields SET uid='$uid'");
return $uid;
}
