破解Navicat Premium数据库账号密码

破解Navicat Premium数据库账号密码

如果你想破解一个已经连接好的数据库密码，可以参考这个方法。

1. 邮件查看已经连接好的数据库属性是这样的

但是密码是******谁也看不懂，博主也从网站上下载过一些星星查看器之类的东西，都无济于事。

1. 接下来就是尝试导出这些连接属性，选择文件---->导出连接，勾选想要导出的数据库，导出.ncx后缀的文件

   

打开导出后的文件，本以为就能看到数据库密码，没想到竟然加密了！！！！

1. 没办法，Google it ，后来发现GitHub上一个大神写了一个PHP，可以直接破解这个密码，一切成功的开始。https://github.com/tianhe1986/FatSmallTools

2. 本地没有安装PHP，so直接找个在线运行的工具https://tool.lu/coderunner/

3. 粘贴代码，修改参数，一切顺利
