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。

关键字： JavaScript 脚本网页加密

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>
