几种常见的cms密码加密方式

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

$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

$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); 
}
