最近在研究魅族M8也就是Windows Mobile6.0系统下的数据库编程，打算开发M8Money个人记账软件，为了让数据库更严谨，秉承一贯的作风，对个人帐号的password字段进行MD5散列，我所使用的是轻量级嵌入式数据库sqlite （仅有几K大小）并没有大多数流行数据库提供的password()内置函数，（但这丝毫没有降低我对sqlite的好感，一款强大的跨平台+嵌入式数据库，支持标准SQL语法，纯粹由C代码组成）。网上找了很多MD5加密的代码，自己又重新研究了一下《密码学》，综合各方面的资料整理封装出独一无二的超精简MD5封装包

The Internet is a lot of MD5 encryption code, but it is a moment to re-examine "Cryptography", a comprehensive package to collate information in all aspects of a unique ultra-streamlined MD5 Package Package
