信息安全课程的实验，含AES、DES、RSA三个加密算法和MD5、SHA-1两个哈希算法的C/C++源代码，可以加密字符串和文件。开发环境为VS，有完整的工程文件及代码，欢迎下载。

AES算法主要包括三个方面：轮变化、轮数和密钥扩展。本文以128为例，介绍算法的基本原理；结合C语言，实现高级数据加密算法AES（AES-128）。-AES algorithm mainly includes three aspects: round of changes, round number and key expansion. In this paper, 128 for example, introduce the basic principles of algorithm combination of C language, the realization of advanced data encryption algorithm AES (AES-128).

取代式密码的存在，已经超过2500年 以上，最早利 用的范例 是在西元600年 左右，内容是以颠倒的希伯來 文构成的。凯萨大帝（Julius Caesar）也曾经使用称为Caesar密码法。方法为将每个字母用其后的第三个字母來 取代。(Replace passwords existence, has more than 2,500 years or more, the first example is using a range of about the year 600 AD, the contents of the text is upside-down Heber future composition. Great Caesar (Julius Caesar) has also been known as the Caesar cipher using the method. Method is used then each letter is replaced by the third letter.)
