压缩加密代码:
<?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
$pos = strpos($contents,'/*Protected by fly ,http://www.hackers.com*/');
if(false === $pos || $pos>100){ // 去除PHP文件注释和空白,减少文件大小
$contents = php_strip_whitespace($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
$encode = '<?php'." /*Protected by fly ,http://www.hackers.com*/\n eval(gzinflate(base64_decode(".$encode.")));\n /*Reverse engineering is illegal and strictly prohibited- (C)fly Cryptation 2019*/ \n?>";
return file_put_contents($filename,$encode);
}
}
return false;
}
//调用函数
$filename='C:\phpstudy\WWW\webshell\1.php';
encode_file_contents($filename);
?>
压缩解密代码:
<?php
$Code = '要解密的编码'; // base64编码
$File = 'test.php';//解码后保存的文件
$Temp = base64_decode($Code);
$temp = gzinflate($Temp);
$FP = fopen($File,"w");
fwrite($FP,$temp);
fclose($FP);
echo "success!";
?>
