查看Navicat加密的数据库密码

背景：本机装的MySQL数据库密码忘记了，打开了Navicat连接过数据库，不过密码是加密的，既然能加密那就能解密，哈哈哈哈。

           解密后发现密码居然是password，好尴尬

1、打开运行窗口，输入regedit，点击确认按钮，打开注册表编辑器

2、在注册表中找到Navicat加密后的密码

• 展开【HKEY_CURRENT_USER】
• 展开【Software】
• 展开【PremiumSoft】
• 展开【NavicatPG】
• 展开【Servers】
• 选择 【MySQL】
• 右侧找到 pwd，双击并复制数值数据

   

3、打开PHP在线运行工具，粘贴解密代码

• 工具地址：https://tool.lu/coderunner
• 复制解密代码到工具中

//需要指定版本两种，11或12
//$navicatPassword = new NavicatPassword(11);
$navicatPassword = new NavicatPassword(12);
 
//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('E75BF077AB8BAA3AC2D5');  // 替换成上一步的数据数值
echo $decode."\n";
?>

4. 修改倒数第三行NavicatPassword的版本值

5、更改倒数第二行decrypt()方法中的字符串为Navicat加密后的密码

6、点击执行，右侧得到解密后的密码
