WebQQ web page hash encryption algorithm PHP version_PHP tutorial

A hash encryption algorithm we found on QQ is the js version. Below we change the hash encryption algorithm of the js version to the php version of the encryption algorithm. I hope the method will be helpful to you.

Due to the recent serious spam messages on QQ, the official chose to make some adjustments to the implementation details of some functions of WebQQ. Among them, there is an additional hash parameter for obtaining the friend's POST value.

This hash is encrypted in js.

The following is the js source code

The code is as follows

Copy code

代码如下	复制代码

Convert to PHP version for processing, the source code is as follows

代码如下

复制代码

/** * 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(, $ord) = unpack('N', mb_convert_encoding($str, 'UCS-4BE', 'UTF-8'));    return

$ord;
