navicat~导出数据库密码

当我们mysql密码忘记了,而在navicat里有记录,我们应该如何导出这个密码呢?

  • 第一步:文件菜单,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,输入PHP代码

//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("复制出来的密码");
echo $decode."

  • 将如下刚刚密码复制进去,
    $decode = $navicatPassword->decrypt("复制出来的密码");
