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.

CRC校验中叠加和校验方法的生成，校验等功能函数源码。-CRC verification and validation methods of superposition generation, calibration source, such as performance function.

自己写的一份RSA算法。可正常执行。控制台程序。(Write your own copy of the RSA algorithm. Can be performed normally. Console program.)

说明：  利用HASH（采用sha-1算法）算法原理，设计数字签名的水印算法，完成嵌入、（提取）验证，(Use HASH (using sha-1 algorithm) algorithm, design of watermarking algorithms digital signature to complete the embedding, (extract) authentication,)

我用C#做的一个对字符串加密的程序，加密对象为26个字母大小写和0到9的数字，实现的是替代法-I used C# do a strings encryption procedures, encryption targeted at 26 case-sensitive alphanumeric 0-9 and figures to achieve the substitution

DES写的文件加密软件,可以用于对整个文件进行加密并且设定加密密码来网络传输!-Written by DES file encryption software, can be used to encrypt the whole document and set the encryption password network!

关于matlab的des源代码，希望能有用，没有乱码(Des on the matlab source code, hoping to be useful, there is no garbled)

文件验证，利用MD5算法做文件的HASH，得到统一结果判断文件内容的一致性-File Hash

基于ATSHA204的加密技术 ，保密性好，破解成本高，在传输线上没有密匙(ATSHA204 based encryption technology, security and good, high cost break in the transmission line is no key)
