适用情况
本地安装 Navicat 软件记录过密码,但本人忘记密码。
实操步骤
打开 Navicat
,找到一个连接,右键 连接属性 , 看到软件本身已经保存了密码,但我们看不到密码。
注册表查找加密后的密码
打开注册表,查找 计算机\HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\navicat\servers
点击 test
,在右侧找到 Pwd
,双击 Pwd
使用代码解密
打开 https://tool.lu/coderunner/
删除原有代码,粘贴下面的解密代码:
解密代码
⚠ 记得修改你的 Pwd 的数值数据!

//需要指定版本两种,11或12
//$navicatPassword = new NavicatPassword(12);
$navicatPassword = new NavicatPassword(11);
//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('decrypt 这里填入你的Pwd的数值数据');
echo $decode."\n";
?>
运行结果
修改密码
如果需要修改密码,在 cmd
修改以下命令:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';
⚠ 重要提示
代码没有错误,但 2024/07/17 我重新试了一下,原来的在线运行网址报错
PHP Warning: Trying to access array offset on value of type bool in /code/main.php on line 70
换了几个别的在线运行网站都报错:
Fatal error: Uncaught Error: Call to undefined function openssl_decrypt() in /box/script.php:63
搜索错误后发现 :在 PHP 中,OpenSSL 扩展库是一个用于实现加密和解密功能的扩展, 用于安全通信。OpenSSL 扩展库可以执行各种加密操作,如数据加密、解密、数字签名等。
这个报错指向 未开启openssl
。但我用的本身就是在线运行 php 代码的网址,不需要配置环境,所以多试了几个网站,目前发现 在线 Php 编译器 - 即时运行 Php 代码 - toolfk 可以使用。遇到报错可以自己多试几个网站。
