wordpress使用PHP代码生成混淆加密PHP文件

wordpress共享是传统的美德！但是，您如果需要卖钱，不放弃努力工作并加密PHP程序，以防止不道德的人转卖它。

使用方法

首先，新建一个 index.php，然后把代码复制进去，修改代码中你要加密的文件名，并把要加密的文件放在同一目录下。接着，访问 index.php，然后就会自动生成加密后的文件在 index.php 的同一目录下

代码

<?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'); 
 ?>

加密效果

$O00OOO00O0O0O0O00O0O0O0O=urldecode("%6E1%7A%62%2F%6D%615%5C%76%740%6928%2D%70%78%75%71%79%2A6%6C%72%6B%64%679%5F%65%68%63%73%77%6F4%2B%6637%6A");$O00O0OOO00O0O00O0OO00O0O=$O00OOO00O0O0O0O00O0O0O0O{3}.$O00OOO00O0O0O0O00O0O0O0O{6}.$O00OOO00O0O0O0O00O0O0O0O{33}.$O00OOO00O0O0O0O00O0O0O0O{30};$O0OO00O00OOO00O0O00O0O0O=$O00OOO00O0O0O0O00O0O0O0O{33}.$O00OOO00O0O0O0O00O0O0O0O{10}.$O00OOO00O0O0O0O00O0O0O0O{24}.$O00OOO00O0O0O0O00O0O0O0O{10}.$O00OOO00O0O0O0O00O0O0O0O{24};$OO0O00OO0O00O0O0O0O00O0O=$O0OO00O00OOO00O0O00O0O0O{0}.$O00OOO00O0O0O0O00O0O0O0O{18}.$O00OOO00O0O0O0O00O0O0O0O{3}.$O0OO00O00OOO00O0O00O0O0O{0}.$O0OO00O00OOO00O0O00O0O0O{1}.$O00OOO00O0O0O0O00O0O0O0O{24};$OO0000OO00O0O0O00O0O0O0O=$O00OOO00O0O0O0O00O0O0O0O{7}.$O00OOO00O0O0O0O00O0O0O0O{13};$O00O0OOO00O0O00O0OO00O0O.=$O00OOO00O0O0O0O00O0O0O0O{22}.$O00OOO00O0O0O0O00O0O0O0O{36}.$O00OOO00O0O0O0O00O0O0O0O{29}.$O00OOO00O0O0O0O00O0O0O0O{26}.$O00OOO00O0O0O0O00O0O0O0O{30}.$O00OOO00O0O0O0O00O0O0O0O{32}.$O00OOO00O0O0O0O00O0O0O0O{35}.$O00OOO00O0O0O0O00O0O0O0O{26}.$O00OOO00O0O0O0O00O0O0O0O{30};eval($O00O0OOO00O0O00O0OO00O0O("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"));
