说明：   本程序实现kaiser密码加密 1.本程序将所有可能出现的英文和符号定义在ASCII表中的“032--126”中的95个常用字符 3.在实现2的基础上，实现控制台对英文文本文件（注意明文和密文都以文件形式存在）的加解密 形式：cipher 源文件名 目的文件名 密钥 E/D（标示加解密）说明：对于加密来说，源文件名就是明文，对于解密来说，源文件名就是密文 ***/
(the program kaiser a password encryption. This program will all of the possible in English and in the definition of symbols ASCII table of the "032-- 126," the 95 commonly used characters in three. in achieving two on the basis of Console achieve the English text files (and expressly close attention to the text of a document form) encryption forms : cipher source document file names Key E/D (marked increase declassified) Note : For encryption, source file name is expressly for declassification, the source file name is ciphertext*** /)
