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:





";
t2.value=strOut;
}

function runCode(){
win=open("about:blank");
win.document.write(t2.value);
win.document.close();
}

function addSlash(str){
return(str).replace(//g,"").replace(///g,"/").replace(/r/g,"r").replace(/n/g,"n").replace(/"/g,""").replace(/'/g,"'").replace(/t/g,"t");
}

function XOR(strV,strPass){
var intPassLength=strPass.length;
var re="";
for(var i=0;ire+=String.fromCharCode(strV.charCodeAt(i)^strPass.charCodeAt(i%intPassLength));
}
return(re);
}

function performPage(strPass){
if(strPass){
document.cookie="password="+escape(strPass);
document.write(XOR(unescape(strHTML),STR.md5(strPass)));
return(false);
}
//**********如果需要自动记住密码,请将下面的注释改成代码
/*
var pass=document.cookie.match(/password=([^;]+)/i);
if(pass){
pass=unescape(pass[1]);
document.write(XOR(unescape(strHTML),STR.md5(pass)));
return(false);
}
*/
//*************
strAskPass="

 ";
strAskPass+="Password:";
strAskPass+="
 
";
document.write(strAskPass);
}
