1.Discuz:
$pw = md5(md5($password).$salt);
2.74cms(骑士CMS):
$password_hash=md5(md5($password).$pwd_hash.$QS_pwdhash);
其中:
$pwd_hash=randstr();
$QS_pwdhash=randstr(16);
代码：
function randstr($length=6)
{
$hash='';
$chars= 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz@#!~?:-=';
$max=strlen($chars)-1;
mt_srand((double)microtime()*1000000);
for($i=0;$i<$length;$i++) {
$hash.=$chars[mt_rand(0,$max)];
}
return $hash;
}
3.phpcms-php
$salt = substr(uniqid(rand()), -6);
$password = md5(md5($password).$salt);
注：uniqid() 函数基于以微秒计的当前时间，生成一个唯一的 ID
4.dedecms-php
$password = $row['pwd'];
$pwd = substr($password, 5, 20);
5.EmpireCMS(帝国CMS)：
提供三种加密方式：
$user_dopass=0;//密码保存形式,0为md5,1为明码,2为双重加密,3为16位md5
..
....
.....
if(empty($user_dopass))//单重md5
{
$password=md5($password);
$oldpassword=md5($oldpassword);
}
elseif($user_dopass==2)//双重md5
{
$salt=make_password($user_saltnum);
$password=md5(md5($password).$salt);
$sa=",".$user_salt."='$salt'";
}
elseif($user_dopass==3)//16位md5
{
$password=substr(md5($password),8,16);
$oldpassword=substr(md5($oldpassword),8,16);
}
