这是一个好用的MD5的C++类；这个类可以加在控制台 程序中也可用在MFC中， 并且提供了详细的错误处理 函数，是一个安全的类。例程是一个MD5的MFC程序， 支持字符串和文件两种输入-This is an easy to use the MD5 of the C++ category this category can be added to the console program can also be used in the MFC and to provide a detailed error handling function, is a type of security. MD5 is a routine procedure of MFC, and documentation to support two types of input string

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）。

PGP Software Development Kit Cryptographic Module  Operational Test Notes WHAT IS IT? ---------- The optest program is used as part of the FIPS 140-2 validation process. In particular, section  TE03.14.02  which requires that the tester shall perform each of the specified services and observe that that they have been implemented  properly.   As a side benefit to clients of the  SDK this code can also be used a good example of how to perform a number of commonly used functions, whether or not the developer intends to run in FIPS mode.   Depending on what option is chosen from the command line the following tests will be run: FIPS MODE SPECIFIC TESTS ------------------ - Invoke the Approved mode of operation (optest.c)     This involves Initializing the SDK, checking
