用Visual Studio 2003编的文件加密程序，能对文件进行二进制读入，再和密码做异或，保存。版本一-Visual Studio 2003 for use of file encryption program, can read a binary file, and then do XOR and password, save. Version 1.0

RSA算法实现，用C++语言实现大数类的构建，可以实现RSA算法加解密文本文件及二进制文件及图像，速度较快-将中文译成英语 RSA algorithm, using C language class structure of large numbers, RSA algorithm for encryption and decryption can text file and binary files and images, faster
