你想逆推？去看看有没有什么工具吧。

其实没有必要研究这，倒是应该逐页面的检查一下系统哪一块有漏洞，没对用户提交的数据进行过滤。

这个代码是OA系统上的一个关键文件，好像处理都在该文件中进行
我想明白下，这段代码是什么意思，然后好对这个OA系统进行修改

人家的收费程序？自己一个一个的逆吧.不是分的事，是太耗时间了,而且还学不到什么新鲜东西...

死了心吧

呵呵收费程序伤不起啊。

这个也不难

前面的代码就是简单的替换，后面的就是base64编码。

$OOO0000O0=$OOO000000***就是替换，类似%74%68%36就是url编码，类似“JE9PME9PMDAwMD0kT09...”就是base64编码。

我分享下之前我遇到加密文件怎么处理的, 砖头轻拍哈
本人之前也在网上找了一番, 直接解密是非常头疼的, 我试过, 发觉加了好几次, 后来放弃了, 除非有工具哈, 我个人是没找到, 不知道其他人找到没
后来发觉, 这种加密文件, 一般都是require进来的,
debug看下 require进来的结果是最容易不过的方法

#8 我已给出了解/码的结果
对于非zend使用的加/密，其实解密程序就在他的代码里，而楼主标0楼的代码就是解/码代码。
其实就是替换和base64解码过程。
解码过程:

自此基本上解/码信/息就足够了。剩下的就是考眼力了，因为作者为了混/淆使用了字母O和数字0
当然更聪明的办法就是使用代码去替换。

"php代码后面还有这段文字"其实也是base64编码，只是把base64编码表打乱了而已。

为了证明一下我#20楼的观点，几年前我写了篇《关于base64加密》把decode_base64($str)函数中的码表替换成

$base64_alphabet = array('r' => 0, 'd' => 1, 'Q' => 2, 'm' => 3, '1' => 4, '0' => 5, 'O' => 6, 'R' => 7,   't' => 8, '/' => 9, 'i' => 10, 'u' => 11, '6' => 12, 'A' => 13, '8' => 14, 'Y' => 15,   'z' => 16, 'F' => 17, 'v' => 18, '5' => 19, 'N' => 20, 'q' => 21, 'j' => 22, 'V' => 23,   'y' => 24, 'B' => 25, 'l' => 26, 'k' => 27, 'Z' => 28, 'H' => 29, 's' => 30, '2' => 31,   'U' => 32, 'K' => 33, 'n' => 34, 'h' => 35, '4' => 36, 'G' => 37, 'X' => 38, 'E' => 39,   'f' => 40, 'S' => 41, '9' => 42, '3' => 43, 'c' => 44, 'b' => 45, 'a' => 46, 'T' => 47,   '7' => 48, 'J' => 49, 'w' => 50, 'M' => 51, 'g' => 52, 'x' => 53, 'o' => 54, 'C' => 55,   'L' => 56, 'I' => 57, 'e' => 58, '+' => 59, 'P' => 60, 'W' => 61, 'D' => 62, 'p' => 63, '=' => 64);

利用这个函数可以直接解码楼主的“php代码后面还有这段文字”.

这个也不难PHP code
define('IN_ADMIN',True);
require_once('include/common.php');
include('include/excel_writer.class.php');
if (GET_INC_CONFIG_INFO("opendate")<=get_date('H',PHP_TIME) &&GET_INC_CO……
高手！！！

说实话当年我写《关于base64加密》时只是想可以用来加密password，只要嵌套的用打乱的不同的base64码表进行加密，要解密起来应该比较困难。但没想到还有解码功能，哈哈。

非常有用的帖子，已经解密出来，谢谢各位大侠！

有些看不到。。说是要登陆。。登陆了也看不到。真是晕！
