      怎樣給PHP源代碼加密?PHP二進制加密與解密的解決辦法

      分享2種PHP的源碼加密方式,此加密方法支持任意PHP版。

      注意,加密后的PHP代碼無需第三方工具解密,像往常一樣,直接運行即可。

      復制代碼 代碼如下:


      <?php
      function encode_file_contents($filename) {
      $type=strtolower(substr(strrchr($filename,'.'),1));
      if ('php' == $type && is_file($filename) && is_writable($filename)) { // 如果是PHP文件 并且可寫 則進行壓縮編碼
      $contents = file_get_contents($filename); // 判斷文件是否已經被編碼處理
      $contents = php_strip_whitespace($filename);

      // 去除PHP頭部和尾部標識
      $headerPos = strpos($contents,'<?php');
      $footerPos = strrpos($contents,'?>');
      $contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);
      $encode = base64_encode(gzdeflate($contents)); // 開始編碼
      $encode = '<?php'."/n eval(gzinflate(base64_decode("."'".$encode."'".")));/n/n?>";

      return file_put_contents($filename, $encode);
      }
      return false;
      }

      //調用函數
      $filename = 'dam.php';
      encode_file_contents($filename);
      echo "OK,加密完成!"
      ?>


      加密方式2:

      復制代碼 代碼如下:


      <?php

      function RandAbc($length = "") { // 返回隨機字符串
      $str = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
      return str_shuffle($str);
      }

      $filename = 'index.php'; //要加密的文件
      $T_k1 = RandAbc(); //隨機密匙1
      $T_k2 = RandAbc(); //隨機密匙2
      $vstr = file_get_contents($filename);
      $v1 = base64_encode($vstr);
      $c = strtr($v1, $T_k1, $T_k2); //根據密匙替換對應字符。
      $c = $T_k1.$T_k2.$c;
      $q1 = "O00O0O";
      $q2 = "O0O000";
      $q3 = "O0OO00";
      $q4 = "OO0O00";
      $q5 = "OO0000";
      $q6 = "O00OO0";
      $s = '$'.$q6.'=urldecode("%6E1%7A%62%2F%6D%615%5C%76%740%6928%2D%70%78%75%71%79%2A6%6C%72%6B%64%679%5F%65%68%63%73%77%6F4%2B%6637%6A");$'.$q1.'=$'.$q6.'{3}.$'.$q6.'{6}.$'.$q6.'{33}.$'.$q6.'{30};$'.$q3.'=$'.$q6.'{33}.$'.$q6.'{10}.$'.$q6.'{24}.$'.$q6.'{10}.$'.$q6.'{24};$'.$q4.'=$'.$q3.'{0}.$'.$q6.'{18}.$'.$q6.'{3}.$'.$q3.'{0}.$'.$q3.'{1}.$'.$q6.'{24};$'.$q5.'=$'.$q6.'{7}.$'.$q6.'{13};$'.$q1.'.=$'.$q6.'{22}.$'.$q6.'{36}.$'.$q6.'{29}.$'.$q6.'{26}.$'.$q6.'{30}.$'.$q6.'{32}.$'.$q6.'{35}.$'.$q6.'{26}.$'.$q6.'{30};eval($'.$q1.'("'.base64_encode('$'.$q2.'="'.$c.'";eval(/'?>/'.$'.$q1.'($'.$q3.'($'.$q4.'($'.$q2.',$'.$q5.'*2),$'.$q4.'($'.$q2.',$'.$q5.',$'.$q5.'),$'.$q4.'($'.$q2.',0,$'.$q5.'))));').'"));';

      $s = '<?php '."/n".$s."/n".' ?>';
      //echo $s;
      // 生成 加密后的PHP文件
      $fpp1 = fopen('temp_'.$filename, 'w');
      fwrite($fpp1, $s) or die('寫文件錯誤');

      ?>


      其實,PHP加密源碼方式有很多,譬如,免費的微盾PHP加密,還有 搞的在線加密,只是phpjm更復雜點而已。

      +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

      另外,分享一個 PHP類,它能對 文本的內容進行 二進制加密 與 解密,代碼如下:

      復制代碼 代碼如下:

      使用方法參考如下:

      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");

      $filename = S_ROOT . './789.php'; // 加密后的文本為二進制,普通的文本編輯器無法正常查看
      file_put_contents($filename, $str);
      // 解密過程
      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);
