navicat~导出数据库密码

当我们mysql密码忘记了，而在navicat里有记录，我们应该如何导出这个密码呢？

• 第一步:文件菜单，导出链接，导出连接获取到 connections.ncx 文件
  这里需要勾选 导出密码！！！ 不然导出的文件里不包含加密的密码
  

• 第二步：找到加密密码，进行破解
  在导出的connections.ncx文件中找到password，然后复制出来

• 打开这个网址：https://tool.lu/coderunner,输入PHP代码

<?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;

}

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(\'复制出来的密码\');
echo $decode.\"\\n\";
?>

• 将如下刚刚密码复制进去，
  $decode = $navicatPassword->decrypt(\'复制出来的密码\');
