怎样破解.rar这种文件，我把密码忘记了，急～～
RAR也是一个非常流行的压缩软件，用户在遗忘RAR压缩包的密码之后可 下载一个CRARK软件来对其进行破解。这是一个命令行实用程序，它主要通过命令行来实现对RAR压缩包的密码进行破解。其命令格式为：“CRARK命令行参数 RAR压缩包文件名”。不过事实上我们一般只需直接使用“CRARK RAR压缩包文件名”命令，利用缺省参数即可达到对RAR压缩包的密码进行破解的目的。
附：CRARK有关命令行参数的含义：
-l 指定最小密码长度
-g 指定最大密码长度
-s 使用用户自己的设置
-d 设置主要词典的文件名
-u 设置用户词典的文件名
-p 设置密码进度文件名
关于EXCEL解密
要看设置的什么密码，如果是工作簿密码就只有暴力破解了，这种几率小的可怜！如果是工作表密码：就按ALT+F11打开VBA，新建宏模块：

6、关闭编辑窗口；
7、依次点击菜单栏上的工具---宏-----宏,选AllInternalPasswords,运行,确定两次；
等一会,就会出现以下对话框：这就是Excel密码对应的原始密码(此密码和原先设置的密码都能打开此文档。如果是别人的文档，你又想恢复密码设置，就可以用此密码进行保护，他就能用他设置的密码打开，你可以试试，很有趣的。字母一定要大写)：
再点击确定。Excel的原始密码就被清除了!!
