• 首先需要导出连接

image-20210907092328452

  • 导出后拿到 .ncx 后缀文件

  • 打开文件找到 password

  • 使用PHP解码，如若本地没有PHP环境，可以使用在线环境

  • 复制以下PHP代码

    //$decode = $navicatPassword->decrypt('15057D7BA390');
    $decode = $navicatPassword->decrypt('E75BF077AB8BAA3AC2D5');
    echo $decode."\n";
    ?>

  • 替换 $decode = $navicatPassword->decrypt('E75BF077AB8BAA3AC2D5'); 即可

    ❗️如果解码后是乱码将 $navicatPassword = new NavicatPassword(11); 替换成 12
