Navicat切換到DBeaver，如何同步連接信息

公司不讓用Navicat了怎么辦？可以選擇DBeaver來替換，怎么才能將Navicat中的DB連接信息導入到DBeaver呢？

1. 在Navicat中導出DB連接信息
   

   最終會得到一個connections.ncx文件

2. 在DBeaver中導入連接

   
   
   
   
   

3. 修改連接中的密碼

   此時導入的連接不能用，因為密碼是經過Navicat加密的，在DBeaver中不能使用，需要重新更新密碼。密碼忘記了怎么辦？

   

   用文本編輯器打開文件connections.ncx，查看密碼

   

   但是該密碼為密文，怎么獲取到它對應的明文呢？需要用到網上的一段PHP代碼，該代碼可以通過在線運行：https://tool.lu/coderunner/

   代碼如下：

   <?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 decryptEleven($upperString)
       {
           $string = hex2bin(strtolower($upperString));
            
           $round = intval(floor(strlen($string) / 8));
           $leftLength = strlen($string) % 8;

           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) {

       }
        
       protected function decryptTwelve($upperString)

           return openssl_decrypt($string, 'AES-128-CBC', $this->aesKey, OPENSSL_RAW_DATA, $this->aesIv);
       }
   };
    
    
   //需要指定navacat版本兩種，11或12
   $navicatPassword = new NavicatPassword(11);
    
   //解密，括號里面寫入navicat加密后的密碼
   $decode = $navicatPassword->decrypt('xxxx');
   echo $decode."\n";
   

   使用方法如下：
   
   
   

4. 連接成功，正常使用即可
