密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.

用MFC实现的对任意长度的文件的MD5加密，得到的是标准的32位十六进制数-Using MFC to achieve for any length of document MD5 encryption, receive the standard 32-bit hexadecimal number

算法参考于《密码编码学及网络安全》上关于RSA加密算法的定义。相关程序在Visual C++ 6.0上能正确运行（估计在其他C语言编程环境下也能运行吧），程序里面详细写上了注解，希望能够给你带来帮助。
