Navicat中怎么查看数据库密码

原文链接：这辈子_安静的努力着
第一步:导出链接，导出连接获取到 connections.ncx 文件

这里需要勾选 导出密码！！！ 不然导出的文件里不包含加密的密码

第二步：找到加密密码，进行破解

在导出的connections.ncx文件中找到password，然后复制出来

打开这个网址：https://tool.lu/coderunner，将如下刚刚密码复制进去，

$decode = $navicatPassword->decrypt('复制出来的密码');

//需要指定版本两种，11或12
//$navicatPassword = new NavicatPassword(11);
//这里我指定的12的版本，原先指定的11，执行之后的密码是乱码
$navicatPassword = new NavicatPassword(12);
 
//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('复制出来的密码');
echo $decode."
";
?>

然后在网页上面执行代码，就可以得到密码了
