Delphi:Delphi采用MD5 加密的例子，关于MD5，我想不用多说了吧，使用最为广泛的简单加密方法了，遍及WEB开发，MD5不但可对字符串加密，也可对文件加密，如果您还对Delphi下的MD5加密不太熟悉的话，那么建议你参考本源码实例，学习一下加密的方法吧。

-Delphi: Delphi uses MD5 encryption example, about the MD5, I think it goes without saying, the most widely used encryption method is simple, and throughout the WEB development, MD5 encrypted string can not only, but also for file encryption, if you have MD5 encryption for under Delphi are not familiar with, then I suggest you refer to the source code examples, learn about the encryption method it.
