    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:


    <?php

    class text_auth

    使用方法參考如下:
    // 加密過程
    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);
