前言
- 现在数据库密码都是自动保存的,时间一长就会忘记某一个数据库的密码
- 但是Navicat保存的数据库密码又是加密的,这时候就需要破解来获取密码
- 整理内容来自百度经验
一、 首先打开注册表,找到navicat中对应的数据库加密密码
- 使用
win+R
键打开命令行,输入 regedit
进入注册表

- 找到图片中对应目录下数据库的
PWD
,打开并复制加密密码

二、 然后去在线工具运行php代码破解加密内容获取密码
- 打开在线工具
- 复制最下边的代码到在线工具页面中
- 根据自己使用的navicat版本选择对应的版本号,修改
decrypt('A3E590714589C4E9F7');
中的内容为刚才复制的字符串

- 运行获得密码【如果选择12版本不对,可以尝试11,我个人navicat版本是12,但是使用版本号为11才能破解成功】
