查看Navicat已连接的密码

说明：有时可能我们早已忘记Navicat中已连接的密码了，但是这个密码我们还是有需要用到的。我们可以使用另外一种方式来把咱的密码获取的出来。

1、导出可以成功连接数据库的连接

2、打开导出的.ncx文件
找到Password这个属性复制

3、打开在线运行工具
在线运行工具复制一下代码进入

<?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(12);
$navicatPassword = new NavicatPassword(11);

//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('AE34AB43E081EA95C2EB');
echo $decode."\n";
?>

把你的Password中的值替换为decrypt即可。

拿到密码即可正常连接了。
