Javascript脚本实现静态网页加密实例代码
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：
