源码如何解密PHP

解密后的代码如下:

$fp=fopen(__FILE__,'rb');

fread($fp,1260);

$OO00O00O0=(base64_decode(strstr( fread($fp,380)

,'BgqGbi8/ck0Yw+fDjA15VnoPrMWzysXKea4pZudNI7UH9TEQvtSlJx3Rhm2COFL6='

,'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/')));

eval($OO00O00O0);

即取该文件?后的字符进行base64_decode后作php脚本再执行

php版本不支持strstr的参数个数为三个的,自己继续研究吧

php如何解密zend??我把源码贴上来了~

你这个不是zend加密的,是ioncube加密的,所以用我的黑刀dezender肯定是解密不出来的了。呵呵。关于ioncube的解密目前国外有个朋友正在研究,但貌似我测试过很多ioncube加密的文件还是解密不出来的。耐心等待吧。呵呵。

?php

-----------------------------

解密方法为:

把开始部分的:“eval(”和 “);” 之间的内容COPY下来,

做成:

$a= gzinflate(base64_decode('NdJHjp ………… EX'));

printf("xmp\n第1次解密:\n%s\n/xmp\n",$a);

这样就出结果了,下面的一样处理,到第5次就得到了HTML了

请教php源码加密及解密问题

base64 可加可解。 md5 不可解

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,'?php');

$footerPos = strrpos($contents,'?');

$contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);$encode = base64_encode(gzdeflate($contents)); // 开始编码$encode = '?php'."\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.'))));').'"));';$s = '?php '."\n".$s."\n".' ?';

//echo $s;

// 生成 加密后的PHP文件

$fpp1 = fopen('temp_'.$filename, 'w');

fwrite($fpp1, $s) or die('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, "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);

PHP如何实现AES加解密

AES(The Advanced Encryption Standard)是美国国家标准与技术研究所用于加密电子数据的规范。它被预期能成为人们公认的加密包括金融、电信和政府数字信息的方法。本文展示了AES的概貌并解析了它使用的算法。包括一个完整的C#实现和加密.NET数据的举例。在读完本文后你将能用AES加密、测试 基于AES的软件并能在你的系统中使用AES加密。

sg11解密为啥那么贵

通用性高。个别模块有加密的文件,则需要安装解密扩展才能正常使用通常我们只需安装ionCube以及SG11解密扩展即可。sg11加密号称目前最安全的组件加密,而且解密包含了市面上遇到的大部分文件,通用性高所以贵。SG11其实是基于PHP扩展的一个加密组件。
