Javascript脚本实现静态网页加密

    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>
<script>
