Navicat 查看导出连接的密码 破解保存的密码 + 密码解密|navicat查看密码方案

解决问题：

我们经常使用navicat连接数据库，有时候时间久了之后，会忘记之前的密码，那么现在我们有办法获得只要正常连接的数据库的密码

步骤：

1.导出连接connections.ncx，拿到保存到本地的connections.ncx文件中的Password，粘贴到下面的代码中

2.登陆https://tool.lu/coderunner/，使用PHP在线运行工具，粘贴下面添加密码后的代码

    }
};
 
 
//需要指定navacat版本两种，11或12
$navicatPassword = new NavicatPassword(11);
 
//解密，括号里面写入navicat加密后的密码
$decode = $navicatPassword->decrypt('E75BF077AB8BAA3AC2D5');
echo $decode."\n";
?>

3.点击执行之后，就会得到真实密码
