Navicat查看数据库的密码

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

1. 使用win+R键打开命令行，输入 regedit进入注册表

2. 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

1. 打开在线工具
2. 复制最下边的代码到在线工具页面中
3. 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

4. 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】
