CRC32检查

在原作者Jim Gillogly代码的基础上修改优化，并实现C++改写。实现了DES加密。当然，密钥可在源文件中修改，或提供修改的接口函数。-the originator Jim Gillogly code revision on the basis of optimization, and to achieve C rewritten. Implementation of DES encryption. Of course, the key in the source documents changes, or amendments to provide the interface function.

GetDiskSerial.DLL 是一个标准的Windows动态链接库，它能够让您在你的程序中简单地获取硬盘出厂序列号。理论上讲，硬盘出厂序列号在全球都是唯一的，所以您可以利用此序列号来产生软件的机器码。 GetDiskSerial.DLL 已经成功的应用在各种流行的开发语言，比如Delphi, C++Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, PowerBuilder, Visual Foxpro, Clarion。产品包里已经包含以上开发语言的调用实例。 -GetDiskSerial.DLL is a standard Windows dynamic link library, which allows you to program in your hard drive a simple access to the factory serial number. In theory, the hard disk factory serial number is unique in the world, so you can use this serial number to generate the software machine code. GetDiskSerial.DLL has successfully used in a variety of popular development languages, such as Delphi, C++ Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, PowerBuilder, Visual Foxpro, Clarion. Product package already contains a call to an instance of the above development language.

AES（The Advanced Encryption Standard）是美国国家标准与技术研究所用于加密电子数据的规范。它被预期能成为人们公认的加密包括金融、电信和政府数字信息的方法。本文展示了AES的概貌并解析了它使用的算法。包括一个完整的C#实现和加密.NET数据的举例。在读完本文后你将能用AES加密、测试 基于AES的软件并能在你的系统中使用AES加密。-AES (The Advanced Encryption Standard) is the National Institute of Standards and Technology for electronic data encryption standards. It was expected to be recognized by encryption including financial, telecommunications and government of digital information. This paper showed a picture of AES and its use of analytic algorithm. Including a complete C# and encryption.NET data, for example. After reading this you will be able to use AES encryption, AES-based testing and software in your system to use AES encryption.
