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:
<script type= "text/javascript" > function getHash(b, i) { for ( var a = i + "password error" , s = "" , j = [];;) if (s.length <= a.length) { if (s += b, s.length == a.length) break } else { s = s.slice(0, a.length); break } for ( var d = 0; d < s.length; d++) j[d] = s.charCodeAt(d) ^ a.charCodeAt(d); a = [ "0" , "1" , "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" , "A" , "B" , "C" , "D" , "E" , "F" ]; s = "" ; for (d = 0; d < j.length; d++) s += a[j[d] >> 4 & 15], s += a[j[d] & 15]; return s; } </script>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( 'N' , mb_convert_encoding( $str , 'UCS-4BE' , 'UTF-8' )); return $ord ; } /* End of file commons.php */查看更多关于WebQQ网页hash加密算法PHP版 - php高级应用的详细内容...
