Description: 在通信网络的两端，双方约定一致的Key，在通信的源点用Key对核心数据进行DES加密，然后以密码形式在公共通信网（如电话网）中传输到通信网络的终点，数据到达目的地后，用同样的Key对密码数据进行解密，便再现了明码形式的核心数据。这样，便保证了核心数据在公共通信网中传输的安全性和可靠性。-communications networks in the two ends, the two sides agreed unanimously the Key, In communications with the source Key to the core DES data encryption, Then a password in the form of public communication networks (such as the telephone network) transmission of the communication network in the end, data arrived at their destination, Key used the same password for data decryption, it depicts the code forms the core data. This will ensure that the core data in the public telecommunication network transmission security and reliability.

Description: DES加密解密程序的主程序在 FileDES类中
运行时使用的例子是本目录下的111.doc文件，运行后自动生成222.doc文件和333.doc文件。
其中111.doc文件加密后的文件是222.doc文件，222.doc文件解密后文件是333.doc文件。
可以操作的文件类型我实验了TXT、DOC、JAVA等都没有问题,且Word文档中包含图片也没问题-DES encryption and decryption procedures of the main program at run-time class FileDES used example is the catalog under 111.doc documents, running 222.doc automatically generated files and documents 333.doc. 111.doc document which the document is encrypted 222.doc document, 222.doc document after the document was declassified documents 333.doc. Can operate file type I experiment a TXT, DOC, JAVA and so there is no problem, and the Word document contains pictures have no problem

Description: 利用Visual C++ .net2003开发的一款用于保护文件的小程序。
对文件产生MD5值同时对源文件用DES加密，并用私钥加密签名。
对加密文件解密，验证用公钥解密签名与解密文件的MD5值比较，以判断文件是否被修改。
遇到的问题：微软提供的签名函数可能有问题，无论用公钥还是私钥签名，用公钥、私钥（任一）均可解密。怪！希望在此与大家交流交流。-The use of Visual C++. Net2003 developed a document for the protection of small procedures. MD5 value of the document produced at the same time the source file using DES encryption, and signature private key encryption. Encrypted files decryption, authentication using public key to decrypt the signature and decrypt files MD5 value to determine whether a document is modified. Problems encountered: Microsoft to provide the signature function may be a problem regardless of whether it uses a public key or private key signature, using public key, private key (any one) can be decrypted. Strange! Would like to exchange with the U.S. exchanges.

Description: Des算法是一种标准的对称加密算法，其精华就是明文经过一系列的复杂变化后，一般在不知密码的情况下要把它的恢复很难。
算法可以由四个部分描述：
1.获取16个子密钥
2.初始置换置换函数ip
3.加密函数f
4.末置换函数
