7天啊，绝望的时候许下一个愿：来世一定做个合格的IT民工！
“做个这样的接口，用C语言写”
“嗯，这个简单
结果……，第1天：-_-, 2天：-_-!, 3天：-_-!!!, 4天： @_@!!!, 5天，6天，7天：！@*&（@……！
曾经，在来这的坐车上，时间过得如此慢。
@brief /一个计算MD5值的C函数，支持中文，结果要和getmd5.html执行的结果一样
那一天,我的第一次！
十分钟：找到rfc1321文档，心想，这任务也太简单了吧，老大真的……，于是准备把古老的代码排版漂亮些;
二十分钟：代码美化完毕，测试下。求“hello world”md5没问题，搞定。
无聊，输入“我是天才”测试下， 结果，结果凌乱了，难道代码，不对，是上天嫉妒我？
于是输入，“我就是天才”，结果，结果……。
恩，于是google, 百度， bing ===》》 编码问题？转UTF-8？还是……！
我就像一只小船，从此迷失在代码的海洋里……，7天啊，各种版本md5,各种转码，……恨不得甲骨文都转下。
似乎快到岸边的时候，被一阵大浪打得windows当成了linux!!!!
终于，想起小船上还有女友送我的一个许愿瓶，我拆开里面拆好的桃心，附上仅有的100大洋，用血写下了一个愿望“上天你就不要再嫉妒我了，让我过了吧”！
