Javascript脚本实现静态网页加密,阅读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

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:

代码如下:

}

#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;
