navicat导出所有数据库连接详情并解密密码

记一次从navicat迁移到其他软件，由于数据库比较多，有些密码都在项目里面找起来比较麻烦，于是利用navicat批量导出连接的功能去导出连接和密码

步骤

导出连接信息文件

点击文件-导出连接

全选之后选择保存位置，并勾选导出密码，点击确定之后完成导出

打开导出的文件

如果本机有JDK1.8+环境，请直接跳到下面一步

导出默认名称是connections.ncx，重命名后缀为.xml格式，然后用编辑器打开，最好是格式化一下，看着更清晰

可以看见里面的一行Connection就对应你的一个连接

关键字段说明：

一般情况下，拿Host Port UserName Password Database就足够了

解密密码

适用于本机有JDK1.8+环境的，支持批量查看

使用方法：

克隆项目并在编译器中运行

或者

直接下载我打包好的Jar

然后在弹出的界面中选择ncx文件显示即可

解密密码第二种办法

适用于无java环境的

出处：https://github.com/tianhe1986/FatSmallTools

使用方法：

访问 https://tool.lu/coderunner/ 在线运行php

复制下面代码进去，并修改倒数第二行密文的值为xml中获取到的Password值

use FatSmallTools\NavicatPassword;
 
//需要指定版本，11 或 12，12 以上用 12，以下用 11
$navicatPassword = new NavicatPassword(12);
//$navicatPassword = new NavicatPassword(11);
 
//解密
$decode = $navicatPassword->decrypt('密文');
echo $decode."\n";

可以看到，正常输出了密码123456
