MD消息摘要程序，MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。-MD news summary procedures, MD5 to 512 groups to deal with the importation of information and each group was divided into 16 groups of 32 seats, after a series of processing, the output from the algorithm four groups composed of 32, these four sub-32 will generate a cascade 128 the hash value.

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.
