WebQQ网页hash加密算法PHP版

由于最近QQ垃圾信息群发严重,官方选择将WebQQ部分功能实现细节方面做了点手脚,其中获取好友的POST值多了一个hash参数,这个hash是在js里加密完成的,以下是js源码:

function getHash(b, i) { 

for (var a = i + "password error", 

s = "",  

j = [];;) if (s.length

if (s += b, s.length == a.length) break 

} else { 

s = s.slice(0, a.length); 

break 

}    

for (var d = 0; d

a = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "B", "C", "D", "E", "F"]; 

s = "";  

for (d = 0; d > 4 & 15], 

s += a[j[d] & 15]; 

return s; 

} 

 

转成PHP版本处理,源码如下:

<?php
/** 
 * 获取好友时的POST参数Hash算法
 *
 * public
 * @param string $qq qq号
 * @param string $ptwebqq cookies中的ptwebqq
 * @return string
 */
function get_hash($qq, $ptwebqq) {
    for ($a = $ptwebqq . "password error", $s = "", $j = array();;) {
        if (strlen($s) <= strlen($a)) {
            $s.= $qq;
            if ($s == strlen($a)) break;
        } else {
            $s = substr($s, 0, strlen($a));
            break;
        }
    }
    for ($d = 0; $d < strlen($s); $d++) {
        $j[$d] = uniord(substr($s, $d)) ^ uniord(substr($a, $d));
    }
    $a = array(
        "0",
        "1",
        "2",
        "3",
        "4",
        "5",
        "6",
        "7",
        "8",
        "9",
        "A",
        "B",
        "C",
        "D",
        "E",
        "F"
    );
    $s = "";
    for ($d = 0; $d < count($j); $d++) {
        $s.= $a[$j[$d] >> 4 & 15];
        $s.= $a[$j[$d] & 15];
    }
    return $s;
}
/** 
 * 模拟 JavaScript charCodeAt函数
 *
 * protected
 * @param string $str
 * @return int
 */
function uniord($str) {
    list(, $ord) = unpack(&#39;N&#39;, mb_convert_encoding($str, &#39;UCS-4BE&#39;, &#39;UTF-8&#39;));
    return $ord;
}
