在使用专业数据库软件Navicat 是都是习惯性地保存了默认密码,但是久而久之后 就会忘记数据库密码,然后自己也没备份,软件上面不可以直接查看填写密码, 这就很不舒服了,
但是,有个小技巧,可以查看navicat 已连接保存的密码。
第一步:首先去 导出连接
导出连接获取到 connections.ncx 文件
这里记着 导出密码!!! 不然导出的文件里不包含加密的密码
用notepad++打开,然后找到 文件里 password 字段的值
把它复制出来
第二步:开始破译密码
多亏一位Github:https://github.com/tianhe1986/FatSmallTools上的大佬写了个程序;可以直接破解这个加密密码
程序是php语言的;如果本地没装php也没关系(也可以弄个服务器测试) , 直接找个在线运行的工具 https://tool.lu/coderunner/
把代码粘上去就行了
然后把刚复制的 加密密码 替换倒数第二行 里的值 , 然后运行就行了
$decode = $navicatPassword->decrypt('999239DEBFA1960BCCB12566F1F417A6');
附带代码行
<?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 = $this->encryptBlock($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); } } 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'); $decode = $navicatPassword->decrypt('999239DEBFA1960BCCB12566F1F417A6'); echo $decode."\n";
最后注意下:乱码
可能解码的时候遇到乱码,这时只需要修改一下指定的版本就行了
可能11版本是乱码。
给他修改成12版本就正常了,具体测试看那个正常。
