目前ASP和VB使用的MD5代码都比较长，通常12K左右。运行速度自然很慢了。还有hmac-md5加密的ASP代码，都是只支持英文字符。不支持中文的。



经过我多年的研究，发现了系统都有一个简单的md5函数库，可以直接调用。于是我就写了标准md5和hmac-md5两个加密函数示例，都有专门处理中文编码的过程。同样这个代码也可以用到VB中，把Server.对象去掉即可。当然其它程序如VC／dephi等都可以利用系统这个函数库的。这个代码在很多服务器系统和虚拟主机上测试通过。是微软自身的。兼容性也很好。

-MD5 code using ASP and VB longer than that, usually 12K. The running speed is very slow. Hmac-md5 encrypted ASP code are only support English characters. Does not support Chinese. After my many years of research, found that the system has a simple md5 function library, you can directly call. So I wrote a standard md5 and hmac-md5 the two encryption function example, have a special deal with the Chinese encoding process. The same code can also be used in VB Server. Objects can be removed. Of course, other programs, such as VC/dephi and so can take advantage of the library in the system. This code in the test by many server systems and virtual host. Microsoft itself. Compatibility is also very good.
