大伙平时周末都忙啥？昨天没事研究了下QQ自动登录的，java实现的代码，有人要么？

周末闲着没事，看朋友在玩腾迅的那些个SNS游戏，打趣问我以前不是写过kaixin001的外挂程序，为啥不干脆再写个腾讯的，毕竟腾讯的用户多很多。于是也想尝试下。可是一开始就卡在QQ自动登录这里了~~

先是验证码的问题。自动识别验证码-。-没研究过，弄不出来。。只好采取折中的办法：自动把验证码图片下载下来放到本地目录，同时将cookie verifysession码给保存起来，作为登录时的cookie提交。

开玩开心网写外挂的思路，把form表单和隐藏域的值提交到QQ登录的表单，发现老是密码错误。。。觉得不对劲，于是截了个包看了下。果然，是加过密的密码提交的。。。

可以肯定的是在客户端JS加密，于是在一堆JS文件中翻出一个comm.js，找到了加密的那段JS。心想偷个懒先，JAVA6里不是可以用ScriptEngine来调用JS函数嘛，于是写了段JAVA调用JS的代码，将原始密码加密、发送。。。。还是登录失败！！

于是慢慢调试，发现貌似ScriptEngine调用的JS函数和用JS直接调用该函数，得到的结果竟然不一致！！（由于函数里有大量位运算操作，可能是Java的ScriptEngine和页面JS解释器的位数不一致吧？哪位仁兄有去仔细研究过的，来共享下知识嘛~~）。。。

没办法，只好自己去研究下那个加密函数，看了一下午才弄明白。。
QQ密码加密时，是先将初始密码先经过md5加密得到一个32位的密文，再将密文+4位验证码得到３６位密文，再将３６位密文进行三次MD5加密，就得到最后的发送密码了。
看来如果想通过截取QQ数据包来破解qq密码的可能性是几乎不存在了。。至少以俺的水平是不可能做到了。。。 T_T

接下来的“抢车位”自动停车、贴条的啥功能，“开心农场”种地偷菜的功能，技术上应该没多大问题了，可问题是…周末过完了。。。哎~~~

有源码共享吗？

贴上来共享下撒。

懒得写注释了。。要是啥地方不明白就问我吧

学习了，最近在搞RSA加密，也是在前台自动生成一个随机数，用脚本对随机数加密，然后用加密的随机数加密密码，再将两个加密数据提交到后台，进行解密。

不错，有点想法
