一、查看navicat保存的密码

1. 进入注册表

 win + R
输入 regedit 回车

在这里插入图片描述

2.找到 navicat 中存储的密码

Navicat针对不同的数据库,它所存放的地点是不一样的

MySQL HKEY_CURRENT_USER\Software\PremiumSoft\Navicat\Servers\

MariaDB HKEY_CURRENT_USER\Software\PremiumSoft\NavicatMARIADB\Servers\

MicrosoftSQL HKEY_CURRENT_USER\Software\PremiumSoft\NavicatMSSQL\Servers\

Oracle HKEY_CURRENT_USER\Software\PremiumSoft\NavicatOra\Servers\

PostgreSQL HKEY_CURRENT_USER\Software\PremiumSoft\NavicatPG\Servers\

SQLite HKEY_CURRENT_USER\Software\PremiumSoft\NavicatSQLite\Servers\

3.mysql存储的密码

HKEY_CURRENT_USER
Software
PremiumSoft
Navicat
Servers

点击要破解密码的数据库,右边会出现 Pwd,值就是加密后的密码

二、解密密码

  1. 参照GitHub上的PHP解密工具 https://github.com/tianhe1986/FatSmallTools

  2. 本地没有安装PHP,直接找个在线运行的工具 https://tool.lu/coderunner/

三、解密

在线运行代码 https://tool.lu/coderunner/ ,使用PHP在线运行工具

//需要指定版本两种,11或12
//$navicatPassword = new NavicatPassword(11);
$navicatPassword = new NavicatPassword(11);
 
//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('221723DF5E050B2521'); // navicat密钥
echo $decode."\n";
?>

替换上面代码中的$decode = $navicatPassword->decrypt(‘XXX’);
