怎样给PHP源代码加密?PHP二进制加密与解密的解决办法

只看该作者 · 发表于 2018-2-14 08:22:16

         分享2种PHP的源码加密方式，此加密方法支持任意PHP版。
注意，加密后的PHP代码无需第三方工具解密，像往常一样，直接运行即可。
[U]复制代码[/U] 代码如下:
');
      $contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);
      $encode = base64_encode(gzdeflate($contents)); // 开始编码
      $encode = '";
      return file_put_contents($filename, $encode);
   }
   return false;
}
//调用函数
$filename = 'dam.php';
encode_file_contents($filename);
echo "OK,加密完成！"
?>
加密方式2：
[U]复制代码[/U] 代码如下:
\'.$'.$q1.'($'.$q3.'($'.$q4.'($'.$q2.',$'.$q5.'*2),$'.$q4.'($'.$q2.',$'.$q5.',$'.$q5.'),$'.$q4.'($'.$q2.',0,$'.$q5.'))));').'"));';
$s = '';
//echo $s;
// 生成加密后的PHP文件
$fpp1 = fopen('temp_'.$filename, 'w');
fwrite($fpp1, $s) or die('写文件错误');
?>
其实，PHP加密源码方式有很多，譬如，免费的微盾PHP加密，还有 www.phpjm.net 搞的在线加密，只是phpjm更复杂点而已。

另外，分享一个 PHP类，它能对文本的内容进行二进制加密与解密，代码如下：
[U]复制代码[/U] 代码如下:
setIter(32);
   }
   function setIter($n_iter)
   {
      $this->n_iter = $n_iter;
   }
   function getIter()
   {
      return $this->n_iter;
   }
   function encrypt($data, $key)
   {
      $n = $this->_resize($data, 4);
      $data_long[0] = $n;
      $n_data_long = $this->_str2long(1, $data, $data_long);
      $n = count($data_long);
      if (($n & 1) == 1) {
         $data_long[$n] = chr(0);
         $n_data_long++;
      }
      $this->_resize($key, 16, true);
      if ( '' == $key )
         $key = '0000000000000000';
      $n_key_long = $this->_str2long(0, $key, $key_long);
      $enc_data = '';
      $w       = array(0, 0);
      $j       = 0;
      $k       = array(0, 0, 0, 0);
      for ($i = 0; $i _encipherLong($data_long[$i], $data_long[++$i], $w, $k);
         $enc_data .= $this->_long2str($w[0]);
         $enc_data .= $this->_long2str($w[1]);
      }
      return $enc_data;
   }
   function decrypt($enc_data, $key)
   {
      $n_enc_data_long = $this->_str2long(0, $enc_data, $enc_data_long);
      $this->_resize($key, 16, true);
      if ( '' == $key )
         $key = '0000000000000000';
      $n_key_long = $this->_str2long(0, $key, $key_long);
      $data = '';
      $w    = array(0, 0);
      $j    = 0;
      $len = 0;
      $k    = array(0, 0, 0, 0);
      $pos = 0;
      for ($i = 0; $i _decipherLong($enc_data_long[$i], $enc_data_long[$i + 1], $w, $k);
         if (0 == $i) {
               $len = $w[0];
               if (4 _long2str($w[1]);
               } else {
                  $data .= substr($this->_long2str($w[1]), 0, $len % 4);
               }
         } else {
               $pos = ($i - 1) * 4;
               if ($pos + 4 _long2str($w[0]);
                  if ($pos + 8 _long2str($w[1]);
                  } elseif ($pos + 4 _long2str($w[1]), 0, $len % 4);
                  }
               } else {
                  $data .= substr($this->_long2str($w[0]), 0, $len % 4);
               }
         }
      }
      return $data;
   }
   function _encipherLong($y, $z, &$w, &$k)

使用方法参考如下：
// 加密过程
view sourceprint?
$text_file = S_ROOT . './456.php';
$str = @file_get_contents($text_file);
require_once S_ROOT . "./text_auth.php";
$text_auth = new text_auth(64);
$str = $text_auth->encrypt($str, "qianyunlai.com");
$filename = S_ROOT . './789.php'; // 加密后的文本为二进制，普通的文本编辑器无法正常查看
file_put_contents($filename, $str);
// 解密过程
view sourceprint
?01 $text_file = S_ROOT . './789.php';
$str = @file_get_contents($text_file);
require_once S_ROOT . "./text_auth.php";
$text_auth = new text_auth(64);
$str = $text_auth->decrypt($str, "qianyunlai.com");
$filename = S_ROOT . './456.php';
file_put_contents($filename, $str);
