Crypotography。在jdk1.5的发行版本中安全性方面有了很大的改进,也提供了对RSA算法的直接支持,现在我们从实例入手解决问题(本文仅是作为简单介绍): <BR><BR>  <STRONG>一、密码学上常用的概念</STRONG> <BR><BR>  1)消息摘要:<BR><BR>  这是一种与消息认证码结合使用以确保消息完整性的技术。主要使用单向散列函数算法,可用于检验消息的完整性,和通过散列密码直接以文本形式保存等,目前广泛使用的算法有MD4、MD5、SHA-1,jdk1.5对上面都提供了支持,在java中进行消息摘要很简单, java.security.MessageDigest提供了一个简易的操作方法:<BR><BR>
