php – ZendFramework – 如何使用Zend_Filter和bin2hex和hex2bin进行加密和解密？

2024年1月31日 169次阅读

当我进行编码时,我有这个随机的“d9b3b2d69bab862a”值.但我无法将其解码回abcd.知道怎么做吗？

编码器/解码器运行：

$tokenIs = Application_Model_Login::getEnc("abcd");
echo $tokenIs . "<br/><br/>";    
echo Application_Model_Login::getDec(hex2bin($tokenIs)); //hints: rawurldecode(..) works

ZF型号：

class Application_Model_Login
{
  private $key  = "thisisakeytolock";
  private $vector= "myvector";

  public static function getEnc($input)
  {   
    $filter = new Zend_Filter_Encrypt(array('adapter' => 'mcrypt', 'key' => $key));
    $filter->setVector($vector);
    $encrypted = $filter->filter($input);
    // bin2hex for user use case     
    return bin2hex($encrypted); //hints: rawurlencode(..) works
  }

  public static function getDec($input)
  {

    $filter = new Zend_Filter_Decrypt(array('adapter' => 'mcrypt', 'key' => $key));
    $filter->setVector($this->vector);
    $encrypted = $filter->filter($input);    
    return $encrypted;
  }  

}

最佳答案 如果你想使用bin2hex来“编码”二进制数据,以便通过http / url轻松传输,那么你可以做以将它反转回二进制：

$encoded = bin2hex($some_binary);
$decoded = pack('H*', $encoded);

你班级的其他小问题是对$key和$vector的引用.
由于两种方法都是静态的,因此它们无法访问$this和$key,而$vector本身是未定义的.

以下代码应该适合您：

class Application_Model_Login
{
    const ENC_KEY = "thisisakeytolock";
    const VECTOR  = "myvector";

    public static function getEnc($input)
    {
        $filter = new Zend_Filter_Encrypt(array('adapter' => 'mcrypt', 'key' => self::ENC_KEY));
        $filter->setVector(self::VECTOR);
        $encrypted = $filter->filter($input);
        return bin2hex($encrypted); //hints: rawurlencode(..) works
        return $encrypted;
    }

    public static function getDec($input)
    {

        $filter = new Zend_Filter_Decrypt(array('adapter' => 'mcrypt', 'key' => self::ENC_KEY));
        $filter->setVector(self::VECTOR);
        $decoded = pack('H*', $input);
        $decrypted = $filter->filter($decoded);
        return $decrypted;
    }
}

或者,您可以在getEnc函数中使用base64_encode,在getDec函数中使用base64_decode. Base64通常用于表示来自加密的二进制数据.
