公钥加密程序，采用非对称密钥，这里以类的形式调用

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 MFC, and it provides a detailed error handling function, is a safe type. MD5 is a routine procedure of MFC to support the two input strings and documents.

MD5的c/c++的一个实现范例,包含MD5开发包-MD5 of c/c++ Realize a sample, including MD5 Development Kit

取主机网卡地址，可用于加密-from mainframe NIC addresses can be used to encrypt

The class has a methode named make_CRC that gets a byte stream and start/end offsets then calculate and return a 16 bit CRC according to determined POLYNAMIAL.The POLYNAMIAL is a private field of the class.

Converst a bit array into a single byte and vice versa

aes的原代码，在ＶＣ＋＋的环境下运行．-Orangk"aes the original code in VC++ environment operation.

DES算法的标准-DES algorithm standard

Motivation - A simple DES core  - Fast and Small Version  - Open Source Compatibility I believe that the core complies to NIST-800-17. However, there has been no formal third party verification. The official NIST specification can be downloaded here: 800-17.pdf. For the Triple DES, the NIST reference is located here: 

md5算法是计算机密码学里经典的算法，实用价值很高，设计的关键在于随机数的产生，本程序采用传统的利用计算机时钟采集种子的办法生成随机数种子。-md5 password algorithm is computer science Lane classic algorithms, highly practical, design is the key to the selection of random numbers, the procedure using the traditional use of computer clock seed collection methods generate random number seed.
