【navicat 密码查看】小技巧navicat 如何查看密码

时间久了，当我们以前连上了navicat 之后，密码忘记了，但是依然能连接，此时我们想查看密码，应该如何操作呢？

步骤1：点击navicat 文件选项，导出连接，勾选需要导出的数据库，导出的时候一定要勾选导出密码

导出之后，我们会得到一个connections.ncx文件中找到password，然后复制出来

复制出来password内容

然后我们要对这个password 密码进行解密。打开小工具 网站：

将如下PHP代码复制进去：

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);//这里我指定的12的版本，原先指定的11，执行之后的密码是乱码$navicatPassword = new NavicatPassword(12); //解密//$decode = $navicatPassword->decrypt('15057D7BA390');$decode = $navicatPassword->decrypt('AE137B98AB3AD0F913EBEF2E8D3C52E9');echo $decode."\n";?>

点击执行，右边运行得到密码。

方法2：可以使用python 代码。
