excel表如何解密

有解密工具,要从网上搜索下载。解密工具在使用之前要关闭防火墙和杀毒软件,因为从理论上说解密工具就类似于一种病毒软件,但是这种软件是针对性,所以不用担心。

如何破解被加密的excel文件

想要对加密的excel文件进行解密的话,主要还是要看你用的什么工具,比如说电脑自带系统对文件进行加密,这样解密也是比较简单的,如果是通过域之盾对文件进行解密的话,就只能通过选择文件申请的方式,否则文件不管是怎么操作都是打不开的。

用什么软件能破解带有密码的ExCeL文件

首先点击“Word/Excel破解”标签进入窗口,点击“浏览”按钮,选择要解密的Word或Excel文件。

其次设置密码的最小长度和最大长度,再设置从小到大还是从大到小。这些设置可以加快破解速度。

然后设置破解字符,即程序在哪些字符范围取值。如我常常使用0-9数字作为密码,因此就选中“数字(0-9)”选项。

最后点击“开始”按钮就可以穷举密码了。点击“暂停”按钮可以暂停程序的运行。如果点击“停止并保存”按钮则可停止程序的运行,并且保存进度,下次可以接着当前进度破解。调入进度的方法是点击工具栏上的“设置”按钮加载进度即可。找到密码时会显示在进度文本框中。

如果需要使用字典请选择“密码字典”选项,会弹出窗口,选择相应的字典,然后点击“确定”就OK了。如果使用自定义字典,可用文本文件设置字典,需要注意的是每行就一个密码,如果你要制作生日密码字典,可使用“多功能密码破解软件”赠送的“生日密码字典生成工具”,它在本软件的安装目录下。灵活使用密码字典能够有效地加快密码破解速度。

小技巧:由于使用穷举法破解速度很慢,可能需要几十个小时,此时你只需点击主界面

工具栏上的“设置”按钮,在弹出的窗口中选中“破解完毕后关闭计算机”选项,那么当计算机穷举完所有密码后会自动关闭计算机。当你下次开启电脑后,只需点击工具栏上的“日志”按钮,就能查看破解出的密码了
