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。
复制代码 代码如下:
-
<?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 并且可写 则进行压缩编码
-
$contents = file_get_contents($filename); // 判断文件是否已经被编码处理
-
$contents = php_strip_whitespace($filename);
-
-
// 去除PHP头部和尾部标识
-
$headerPos = strpos($contents,');
-
$footerPos = strrpos($contents,'?>');
-
$contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);
-
$encode = base64_encode(gzdeflate($contents)); // 开始编码
-
$encode = '."\n eval(gzinflate(base64_decode("."'".$encode."'".")));\n\n?>";
-
-
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:
复制代码 代码如下:
-
<?php
-
-
function RandAbc($length = "") { // 返回随机字符串
-
$str = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
-
return str_shuffle($str);
-
}
-
-
$filename = 'index.php'; //要加密的文件
-
$T_k1 = RandAbc(); //随机密匙1
-
$T_k2 = RandAbc(); //随机密匙2
-
$vstr = file_get_contents($filename);
-
$v1 = base64_encode($vstr);
-
$c = strtr($v1, $T_k1, $T_k2); //根据密匙替换对应字符。
-
$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.'))));').'"));';
-
-
$s = '."\n".$s."\n".' ?>';
-
//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 搞的在线加密,只是phpjm更复杂点而已。

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, "");
-
-
$filename = S_ROOT . './789.php'; // 加密后的文本为二进制,普通的文本编辑器无法正常查看
-
file_put_contents($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, "");
-
-
$filename = S_ROOT . './456.php';
-
file_put_contents($filename, $str);
