php实现源代码加密的方法

新建一个文件index.php（根据情况命名）
再新建一个要加密的文件，比如：hello.php
访问index.php文件将会在当前目录下创建一个文件件create，并且会生成一个已加密好的hello.php文件

index.php源码

<?php

function RandAbc($length=""){//返回随机字符串
	$str = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
	return str_shuffle($str);
}

$filepath = \'hello.php\';
$path_parts = pathinfo($filepath);
$filename = $path_parts["basename"];
$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 $s;

//生成 加密后的PHP文件
!is_dir(\'create/\') && mkdir(\'create/\');
$fpp1 = fopen(\'create/\'.$filename,\'w\');
fwrite($fpp1,$s) or die(\'写文件错误\');
echo \'加密成功！\';
