JAVASCRIPT脚本实现静态网页加密
类别: JavaScript教程 
前两天看见有人问静态网页加密问题，就写了这个代码
思路：
加密时：先把用户的密钥A用md5加密为B,然后用B异或源文件S0得到目标文件S1,把S1存入js变量中。
解密时：询问密钥，然后操作同加密。
因为用了md5，个人认为没有密钥的时候是无法破解的（暴力除外）
大家试用一下哈哈：
源代码如下：
<html>
<head>
<title>Web Encoder</title>
<style>
body {
font-size:12px;
line-height:12px;
background-Color:buttonface;
border-width:0px;
overflow:auto;
margin:0px;
padding:4px;
}
#t1, #t2 {
width:100%;
height:40%;
border-width:1px;
overflow:auto;
height:expression((document.body.clientHeight-100)/2);
}
input {
border-width:1px;
padding-left:10px;
padding-right:10px;
margin:4px;
}
</style>

思路：
加密时：先把用户的密钥A用md5加密为B,然后用B异或源文件S0得到目标文件S1,把S1存入js变量中。
解密时：询问密钥，然后操作同加密。
因为用了md5，个人认为没有密钥的时候是无法破解的（暴力除外）
大家试用一下哈哈：
