eval(function(p,a,c,k,e,d)系列js解密、js格式化排列 _ JavaScript

一个经常见到的东西. 今天再次遇上.. 决定在这存一下.呵

eval(function(p,a,c,k,e,d) 一种压缩混淆js用的.

后面还有一个js代码排列的格式化工具..

在线演示地址:

eval(function(p,a,c,k,e,d)系列js解密：http://vl99.com/webtest/Jstools/jsevalcrack.htm

js格式化: http://vl99.com/webtest/Jstools/jsformat.html

下面是一个解码的代码

<script>
a=62;
function encode() {
var code = document.getElementById('code').value;
code = code.replace(/[rn]+/g, '');
code = code.replace(/'/g, "'");
var tmp = code.match(/b(w+)b/g);
tmp.sort();
var dict = [];
var i, t = '';
for(var i=0; i<tmp.length; i++) {
if(tmp[i] != t) dict.push(t = tmp[i]);
}
var len = dict.length;
var ch;
for(i=0; i<len; i++) {
ch = num(i);
code = code.replace(new RegExp('b'+dict[i]+'b','g'), ch);
if(ch == dict[i]) dict[i] = '';
}
document.getElementById('code').value = "eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--)d[e(c)]=k[c]||e(c);k=[function(e){return d[e]}];e=function(){return'\w+'};c=1};while(c--)if(k[c])p=p.replace(new RegExp('\b'+e(c)+'\b','g'),k[c]);return p}("
+ "'"+code+"',"+a+","+len+",'"+ dict.join('|')+"'.split('|'),0,{}))";
}

function num(c) {
return(c<a?'':num(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36));
}

function run() {
eval(document.getElementById('code').value);
}

function decode() {
var code = document.getElementById('code').value;
code = code.replace(/^eval/, '');
document.getElementById('code').value = eval(code);
}
</script>
<textarea id=code cols=80 rows=20>

</textarea>

<input type=button onclick=encode() value=编码>
<input type=button onclick=run() value=执行>
<input type=button onclick=decode() value=解码>

通常用上面那东西或一些解码出来的东西都是混在一起的.根本没有可读性..

试了几个js格式化的工具都不灵,不是代码不对就是死机.后来终于找到个成功的.这页面还挺有意思呵呵..

。。。解不出来，看起来像是设定cookie的恶意脚本，可以删掉。
