【300分】求一个php解密算法

以前采集的一个站最近联系方式用图片来生成了，导致联系方法无法采集到。

http://www.guijob.com/securite.php?contact= AQUAChwGAAsABAQL
输出到图片的内容：0773-2181632

http://www.guijob.com/securite.php?contact= AQUAChw
输出到图片的内容：0773-

更多内容可以参考这个页面的：http://www.guijob.com/display/jobs/87859.htm

内容应该就是红色的部分，只是被混淆过了，大家随便输入字母会得到不同的图片内容

php只了解皮毛,不知道如何解密。

由于在php论坛等级不够，无法发300分的帖子，我会慢慢加上去的，不行发另外2个100分的帖子给提供思路的童鞋

回复讨论(解决方案)

直接将图片存入数据库？

有的时候是两个字母代表一个数字，有的时候是一个，两个字母有不同的组合也能代表一个数字
如果单独重复的输入ADADAD这样，结果也不是连续的数字
如果输入密码的后半截，输出也不是后半截数据，而是其他数据
暴力破解似乎不太好办，不是密码表，求解算法

这个...谁知道是怎么加密的? 需要有经验的才能看出来.呼叫版主

与其花力气去解加密方法不如图片识别这种图片识别率是100%...

人家的加密算法除非是写得简单了，若不然想轻松解出来并不容易.

掉坑里的路过，这玩意似乎是靠位数识别的
AQUAChwBCQQDCw4J是0773-5872990
AQUACAQBCQQDCw4J是077155872990
第6，7位的小写hw可以成为短横线，但也会影响到前面的数字，但不会影响后面的

测试了几把，应该是对ascii动的手脚，不过我不擅长加密解密。

提供下思路，看看有没有数学高手能找出规律。

楼主提供的:AQUAChw,对应结果为0773-
我尝试去掉w,尝试AQUACh，得到结果为0773
但是单独输入个w，什么结果也得不到，可见w !== -

因此我认为他很可能是整体处理的。

拿AQUACh来说，对应的ascii为65 81 85 65 67 104

我认为他可能是将这个数字列先用什么计算方法合并在一起，再得到0773这个数字的。并且我确信，这个转换也是得到ascii码后再找对应字符的，因为其中不止有数字，还有一些特殊字符。

这个方法可行，找下火车头有这种配置没，嘿嘿。。

不行只能存储加密的字符串，自己用其他语言下载图片来识别了，?(???)?

学习了 ....
