使用Navicat连接后数据库密码忘了，密码找回【亲测有效】

柔情只为你懂 2022-09-07 12:17 549阅读 0赞

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

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 大佬的git地址[https://github.com/tianhe1986/FatSmallTools][https_github.com_tianhe1986_FatSmallTools]

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/][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  
`$decode = $navicatPassword->decrypt('999239DEBFA1960BCCB12566F1F417A6');`  
需要写入的代码

注意乱码问题：  
 可能解码的时候遇到乱码，这时只需要修改一下指定的版本就行了
