Navicat 15获取用户的密码

我使用Navicat连接好了mysql但是密码忘记了；可以通过如下操作找回密码

我使用的Navicat版本是 15.0.27

1、选择文件 --> 导出连接
在这里插入图片描述

2、选择你要知道密码的连接  勾选导出密码（默认位置是桌面）
在这里插入图片描述
3、在Password 这栏找到加密后的密码

4、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

<?php
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 = $this->encryptBlock($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', $this->blowKey, OPENSSL_RAW_DATA|OPENSSL_NO_PADDING);}protected function xorBytes($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);}return $result;}protected function decryptTwelve($upperString){$string = hex2bin(strtolower($upperString));return openssl_decrypt($string, 'AES-128-CBC', $this->aesKey, OPENSSL_RAW_DATA, $this->aesIv);}
};//需要指定版本两种，11或12
//$navicatPassword = new NavicatPassword(11);
$navicatPassword = new NavicatPassword(12);//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('E75BF077AB8BAA3AC2D5');  // 替换成加密的密码
echo $decode."\n";
?>

#我已经试过了，需要指定12版本，11版本会乱码（11版本是解密另一种加密方式的，后面会介绍）

在这里插入图片描述
可以看出密码已经被破译出来了，我的密码是 123456

二、介绍另一种获取用户加密密码的方式

1、打开运行窗口，输入regedit，点击确认按钮，打开注册表编辑器
在这里插入图片描述
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【Navicat】
展开【Servers】
找到你的数据库连接并双击，双击右侧的pwd，复制数据数据（就是加密的密码）
