浅析Navicat中怎么查看已连接保存的密码

怎么查看Navicat已连接保存的数据库密码？下面本篇文章给大家介绍一下查看navicat已保存密码的方法，希望对大家有所帮助！

在使用navicat 是都是习惯性的保存了密码，久而久之后 就会忘记数据库密码， 这就很不舒服了，

但是，这有个技巧，可以查看navicat 已连接保存的密码

首先去 导出连接

导出连接获取到 connections.ncx 文件

这里记着 导出密码！！！ 不然导出的文件里不包含加密的密码

然后找到 文件里 password 字段的值

把他复制出来

下载

开始破译密码

多亏一位Github上的大佬写了个程序；可以直接破解这个加密密码

程序是php的；如果本地没装php也没关系 , 直接找个在线运行的工具 https://tool.lu/coderunner/

把代码粘上去就行了

然后把刚复制的 加密密码 替换倒数第二行 里的值 , 然后运行就行了
