navicat查看数据库密码

1、注册表中密码信息
计算机\HKEY_CURRENT_USER\Software\PremiumSoft\Navicat\Servers\localhost

2、进行php在线密码解密
在线php密码运行平台https://tool.lu/coderunner/
代码如下
`<?php
namespace FatSmallTools;
class NavicatPassword

use FatSmallTools\NavicatPassword;

//需要指定版本，11或12

//$navicatPassword = new NavicatPassword(12);

$navicatPassword = new NavicatPassword(11);

//解密
$decode = $navicatPassword->decrypt('15057D7BA390');
echo $decode."\n";`
