如何解决Navicat已经成功连接,密码忘记的问题

- 1. 如果是win,通过注册表里去找对应的数据,用php解码
- 2. linux/win/苹果桌面情况下,可导出连接看然后去php解密(适用)
- 3. 直接登录navicat,用命令去改密码
- 总结
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www.devze.com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 namespace FatSmallTools; class NavicatPassword { protected $version = 0; protected $aesKey = 'libcckeylibcckey'; protected $aesIv = 'libcciv libcciv '; protected $blowString = '3DC5CA39'; protected $blowKey = null; protected $blowIv = null; public function __construct($version = 12) { $this->version = $version; $this->blowKey = sha1('3DC5CA39', true); $this->blowIv = hex2bin('d9c7c3c8870d64bd'); } public function encrypt($string) { $result = FALSE; switch ($this->version) { case 11: $result = $this->encryptEleven($string); break; case 12: $result = $this->encryptTwelve($string); break; default: break; } return $result; } protected function encryptEleven($string) { $round = intval(floor(strlen($string) / 8)); $leftLength = strlen($string) % 8; $result = ''; $currentVector = $this->blowIv; for ($i = 0; $i < $round; $i++) { $temp = $this->encryptblock($this->xorBytes(substr($string, 8 * $i, 8), $currentVector)); $currentVector = $this->xorBytes($currentVector, $temp); $result .= $temp; } if ($leftLength) { $currentVector = $this->encryptBloBVCuhgBtOHck($currentVector); $result .= $this->xorBytes(substr($string, 8 * $i, $leftLength), $currentVector); } return strtoupper(bin2hex($result)); } protected function encryptBlock($block) { return openssl_encrypt($block, 'BF-ECB', $this->blowKey, OPENSSL_RAW_DATA|OPENSSL_NO_PADDING); } protected function decryptBlock($block) { return openssl_decrypt($block, 'BF-ECB', $this->blowKey, OPENSSL_RAW_DATA|OPENSSL_NO_PADDING); } protected function xorBytes(编程客栈$str1, $str2) { $result = ''; for ($i = 0; $i < strlen($str1); $i++) { $result .= chr(ord($str1[$i]) ^ ord($str2[$i])); } return $result; } protected function encryptTwelve($string) { $result = openssl_encrypt($string, 'AES-128-CBC', $this->aesKey, OPENSSL_RAW_DATA, $this->aesIv); return strtoupper(bin2hex($result)); } public function decrypt($string) { $result = FALSE; switch ($this->version) { case 11: $result = $this->decryptEleven($string); break; case 12: $result = $this->decryptTwelve($string); break; default: 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); $currentVector = $this->xorBytes($currentVector, $encryptedBlock); $result .= $temp; } if ($leftLength) { $currentVector = $this->encryptBlock($currentVector); $result .= $this->xorBytes(substr($string, 8 * $i, $leftLength), $currentVector); 编程客栈}BVCuhgBtOH return $result; } protected function decryptTwelve($upperString) { $string = hex2bin(strtolower($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编程客栈(www.devze.com)。
