应用背景此库是C语言编写的MD5加密源代码，包含MD5.c,MD5.h,简介txt文件MD5.txt及一个测试代码testmd5.c.代码在ubuntu12.04服务器版本成功测试通过。关键技术Message Digest Algorithm MD5（中文名为消息摘要算法第五版）为计算机安全领域广泛使用的一种散列函数，用以提供消息的完整性保护。该算法的文件号为RFC 1321（R.Rivest,MIT Laboratory for Computer Science and RSA Data Security Inc. April 1992）。

说明：  AES算法（即 Rijndael 算法）是一个对称分组密码算法。数据分组长度必须是 128 bits，使用的密钥长度为 128，192 或 256 bits。对于三种不同密钥长度的 AES 算法，分别称为“AES-128”、“AES-192”、“AES-256”。本文在分析了 AES 加密原理的基础上着重说明了算法实现的具体步骤，并用 C++ 实现了对文件的加密和解密。(AES algorithm (Rijndael algorithm) is a symmetric block cipher algorithm.The data packet length must be 128 bits and the key length used is 128,192 or 256 bits.For the three AES algorithms with different key lengths, they are called "aes-128", "aes-192", and "aes-256".In this paper, on the basis of analyzing the principle of AES encryption, the concrete steps of the algorithm are emphatically explained, and the encryption and decryption of files are realized by C++.)
