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.
