程序主要是用VC++6.0 C语言编译软件设计出来的。通过运用基本的库函数，以及常用的数组结构体函数，实现了对源文件中字符的任意右移，从而实现了文件的加密解密过程，此方法简单易行，便于操作。-Procedure is mainly used VC++6.0 C language compiler software designed. Through the use of basic library functions, as well as an array of structures commonly used functions, the realization of the source file in any of the characters shifted to right in order to achieve a document encryption and decryption process, this method is simple, easy to operate.
