base64 php encryption us article method Source code of program himself

文章介绍了两个给php程序自身加密的方法,我们常的方法base64_encode(gzdeflate($contents))这样来加密了,第二种方法不多见有需要的朋友也可以参考一下。

实例1

 代码如下 复制代码

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
$encode = '";
return file_put_contents($filename,$encode);

}
return false;
}
//调用函数
$filename='dam.php';
encode_file_contents($filename);
echo "OK,加密完成!"
?>

实例2

 代码如下 复制代码

function RandAbc($length=""){//返回随机字符串
  $str="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
  return str_shuffle($str);
}
$filename='dam.php';
$T_k1=RandAbc();//随机密匙1
$T_k2=RandAbc();//随机密匙2
$vstr=file_get_contents($filename);//要加密的文件
$v1=base64_encode($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.'))));').'"));';
$s=' '.$s.
'
 ?>';
echo "OK,加密完成!";
//生成 加密后的PHP文件
$fpp1 = fopen('dam.php','w');
fwrite($fpp1,$s) or die('写文件错误');
?>
