展开【HKEY_CURRENT_USER】
展开【Software】
展开【PremiumSoft】
展开【NavicatPG】
展开【Servers】
选择 【MySQL】
右侧找到 pwd，双击并复制数值数据
复制解密代码到工具中

Navicat（11.2.7、12.1.15、15.1.17、16.0.6上述版本均已通过测试）
进入注册表进行查询
使用【Win】+ 【R】组合快捷键，快速打开运行命令框，在打开后面键入命令：【Regedit】打开注册表编辑器
文件路径：
计算机\HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\Navicat\Servers\
以Navicat16为例，通过上方路径，找到注册表中存储密码值的位置（如下图），选中要查看密码的连接名称，双击Pwd项，复制对应的值，至此获得了密文
以Navicat16为例，菜单栏上点击文件，选择导出连接...，一定要选中导出密码！！！导出格式为*.ncx（该ncx本质上是xml文件，文件中包含连接的全部信息）
注：Navicat11版本没有勾选导出密码选项，直接导出即可；Navicat12+版本要勾选【导出密码】选项！
