对所需要保密的文件进行加密，代码简洁易懂。

该程序实现单层的DES加密算法，其中CDes.cpp为源程序，其中调用的文件功能如下：dataofText.txt文件是输入的明文，以换行分割各个数据；dataofKey.txt文件时输入的密钥，以换行分割；dataofDES.txt文件是输出的加密数据，其中包括各轮子密钥以及各轮加密输出，以及最后得到的密文，在文件中都有说明。-the realization of the single DES encryption algorithm, which CDes.cpp to source files, Calling the document which functions as follows : dataofText.txt document is imported specifically, in exchange for various bits of data; dataofKey.txt paper input key to change bits; dataofDES.txt document is the output data encryption, including the wheels round and the key encryption exports, and finally the secret text in the document have been described.
