JavaScript MD5 加密算法

在一般网站开发中,用户登陆的密码都是明码发送的,这样是很不安全的.
解决方法:在提交前,用JavaScript将用户密码进行sha1或md5加密.

首先说说MD5：

MD5用的是哈希函数,在计算机网络中应用较多的不可逆加密算法有RSA公司发明的MD5算法和由美国国家技术标准研究所建议的安全散列算法SHA.

虽说已经被破解（见百度百科），但仍然是我们的加密首选。

说说用JS MD5加密的优点：

由于表单(form)在提交的时候，无论是通过GET方法还是通过POST方法，密码在提交时都会以明码的方式进行发送，很不安全。

如果不是在SSL下传输的数据比较容易被分析出表单提交的密码。

优点：

1、如上所述，增加了安全性，

2、用JavaScript在客户端来加密可以减少服务器端的运算。

这是MD5的js加密代码的DEMO。其中也有MD4和SHA1的JS加密代码。原页面也又包含JS的用法

代码：
