我要评论一直想写一下这篇文章的总结，因为有时真的忘记了，要去网上重新搜索一下之前用过的方法，因此这里记录一下，也为了以后遇到这种问题可以直接看我的文章，而不是到处找，以下为实践篇。
1. 如果是win,通过注册表里去找对应的数据，用php解码
去cmd里输入
regedit
去到对应的注册表
查找navicat的密码保存位置
去到对应的路径下面
计算机\hkey_current_user\software\premiumsoft
可以看到
打开对应的目录，寻找一下servers下要找的数据库，如我要找阿里云的密码
寻找pwd找出来，复制数据
去到
https://tool.lu/coderunner/
复制黏贴一下php解密的代码
<?php

break;

break;

break;
}
return $result;
}

$round = intval(floor(strlen($string) / 8));
$leftlength = strlen($string) % 8;
$result = '';

for ($i = 0; $i < $round; $i++) {
$temp = $this->encryptblock($this->xorbytes(substr($string, 8 * $i, 8), $currentvector));

$result .= $temp;
}

}
public function decrypt($string)

break;
case 12:
$result = $this->decrypttwelve($string);

break;
}
return $result;
}
protected function decrypteleven($upperstring)
{
$string = hex2bin(strtolower($upperstring));
$round = intval(floor(strlen($string) / 8));
$leftlength = strlen($string) % 8;
$result = '';
$currentvector = $this->blowiv;
for ($i = 0; $i < $round; $i++) {
$encryptedblock = substr($string, 8 * $i, 8);
$temp = $this->xorbytes($this->decryptblock($encryptedblock), $currentvector);

{
$string = hex2bin(strtolower($upperstring));
return openssl_decrypt($string, 'aes-128-cbc', $this->aeskey, openssl_raw_data, $this->aesiv);
}
}
use fatsmalltools\navicatpassword;
//需要指定版本，11或12
//$navicatpassword = new navicatpassword(12);
$navicatpassword = new navicatpassword(11);
//解密
$decode = $navicatpassword->decrypt('15057d7ba390');
echo $decode."\n";
将15057d7ba390复制到倒数第二行
点击执行，得到密码
2. linux/win/苹果桌面情况下，可导出连接看然后去php解密(适用)
导出后用notepad++看里面的代码
寻找password值
复制888b51b60b5ff32faf86ac去第一种方法php方法里解密
3. 直接登录navicat,用命令去改密码
通过navicat premium能登陆mysql，但root用户密码忘记了
方法： 用update直接编辑user表
mysql -u root
mysql> use mysql;
mysql> update user set password = password('newpass') where user = 'root'; mysql> flush privileges;
总结
- 从操作上没有卡手的地方
- 不太明白为什么说php是最好的语言，猜测用java写出来也是可以解密的
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
