怎么去掉RAR自解压缩文件的密码!
怎么去掉RAR自解压缩文件(*.EXE)的密码,破解密码的方法也可以! RAR密码很难破解，3-4位还可以 这个也可以？那rar密码不是形同虚设么？爆破也只是靠运气 以前在网上看的一篇文章。。。。。
研究破解RAR密码就等于研究破解AES算法的方法
最近有个RA压缩文件有密码打不,所以上网找些破解rar压缩包的程序，但很失望的是他们都是运行得很缓慢的。在我的pc只可以每秒穷举13~15个密码速度。这样实在太令人失望，相对破解word文档的程序竟然可以达到每秒穷举5~6万个...实在搞不懂。难道真的没有什么好的办法可以快速破解密码。。。。
后来上一些英文网页才查到winrar是使用AES加密算法，所以基本是属于对内容进行分组加密的程序 ，所以rar的输出的加密文件里的解压通常都是用输出的文件流的CRC对比从而测量出文件是不是被正确解密。
那有没有什么快速破解AES算法的程序。。。答案是如果oyjj想出来后可能被fbi查....真得这个算法是公开的一种份长度和密钥长度均可变的分组密码算法，而且AES是1997年的NIST在
全世界公征集的最优化后的对程加密算法Rijndae。。所以要破解只有用l穷举的办法，没有什么的后门可走..
关于AES算法 这篇帖子的作者还给了个C#版的 如下

不知道大家以为怎么样啊？ 楼上强人，小生学习了！ 这么长的程序
时间啊
太难了 我说那末多加密指标都用ＲＡＲ再加密了后才发出去呢！ 楼主呀，看不懂呀，只能学习了。 我是初学者啊!!!!!!!!!/:L 以前用arpr破过,破解6位密码挺快的.
