如何查看Navicat加密的数据库密码
作者:爱学习de测试小白
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,怎么办呢?今天小编给大家分享如何查看Navicat加密的数据库密码,感兴趣的朋友一起看看吧
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
<?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
附录:navicat找出加密的密码
- Navicat(11.2.7、12.1.15、15.1.17、16.0.6上述版本均已通过测试)
- 进入注册表进行查询
使用【Win】+ 【R】组合快捷键,快速打开运行命令框,在打开后面键入命令:【Regedit】打开注册表编辑器
文件路径:
计算机\HKEY_CURRENT_USER\SOFTWARE\PremiumSoft\Navicat\Servers\
以Navicat16为例,通过上方路径,找到注册表中存储密码值的位置(如下图),选中要查看密码的连接名称,双击Pwd项,复制对应的值,至此获得了密文
Navicat导出(推荐)
以Navicat16为例,菜单栏上点击文件,选择导出连接...,一定要选中导出密码!!!导出格式为*.ncx(该ncx本质上是xml文件,文件中包含连接的全部信息)
注:Navicat11版本没有勾选导出密码选项,直接导出即可;Navicat12+版本要勾选【导出密码】选项!
解密密文
