js加密解密的问题

Question

汗！！好象用了好几种加密的1.无用内容混乱以及换行空格TAB大法
2.任意添加NUL空字符（十六进制00H）
3.使用Microsoft出品的脚本编码器Script Encoder来进行编码
好象都用到了

Answer 1

简单了，在return前alert下就看见代码了
eval((function(){a="Scroller={speed:10,8dC.;d.while(dC.+C.}} J8N;d=5;&&M4M}d&&dM4dM}%4%} 0J8a,F4(F,fa@7a.4a.LP
+F7Jend8e66.cancelBubble=true;6.Value=fa@;}&&(E(7J8di=Hner3||5.G3;hN.3;a=(Ed>ah-d>i7e@{-(h-d)7}e@{a=a+(d-a}To(0,aEa==a}=aJHit8KwHdow,
A
,A7,A82P;l=9;d=locatiP;D&&D.HdexOfL#
)!=-1&&(l
/
+l=C)Kl,
Gck
,endEl.PGck=2l=this.hash.substr(1E9.name==l;i=setILL+(9)+
)
,107}}}}}};Hit()",b=48;while(b>=0)a=a.replace(new RegExp("
%23456789@ACDEFGHJKLMNP".charAt(b),"g"),("\042Scroller.entfunction(offsetParscrollwindow.returndocumattachEvntervala=.getElemsByTagName(
a
);if(offsetTop){for(i=0;i<a.length;i++.pathnamea+=Math.ceil((d-ae.stopPropagationTopa.addEvListenerbody)/speede.prevDefaultclearI(i)pageYOffsetend(this);Height .Elemev)}:a[i]lseload=dl.href);b,dcliin},((
.=.=C||on".split(""))[b--]);alert(a);return a})());

var aaa   eval((function(){a="Scroller={speed:10,8dC.;d.while(dC.+C.}} J8N;d=5;&&M4M}d&&dM4dM}%4%} 0J8a,F4(F,fa@7a.4a.LP
+F7Jend8e66.cancelBubble=true;6.Value=fa@;}&&(E(7J8di=Hner3||5.G3;hN.3;a=(Ed>ah-d>i7e@{-(h-d)7}e@{a=a+(d-a}To(0,aEa==a}=aJHit8KwHdow,
A
,A7,A82P;l=9;d=locatiP;D&&D.HdexOfL#
)!=-1&&(l
/
+l=C)Kl,
Gck
,endEl.PGck=2l=this.hash.substr(1E9.name==l;i=setILL+(9)+
)
,107}}}}}};Hit()",b=48;while(b>=0)a=a.replace(new RegExp("
%23456789@ACDEFGHJKLMNP".charAt(b),"g"),("\042Scroller.entfunction(offsetParscrollwindow.returndocumattachEvntervala=.getElemsByTagName(
a
);if(offsetTop){for(i=0;i<a.length;i++.pathnamea+=Math.ceil((d-ae.stopPropagationTopa.addEvListenerbody)/speede.prevDefaultclearI(i)pageYOffsetend(this);Height .Elemev)}:a[i]lseload=dl.href);b,dcliin},((
.=.=C||on".split(""))[b--]);aaa=a;return a})());
 document.write(aaa.toString().replace(/</g,"&lt;").replace(/>/g,"&gt;"));
解密出来就是这样的Scroller={speed:10,offsetParent:function(d){offsetParent=d.offsetTop;if(d.offsetParent){while(d=d.offsetParent){offsetParent+=d.offsetTop}}return offsetParent},scrollTop:function(){body=document.body;d=document.documentElement;if(body&&body.scrollTop){return body.scrollTop}if(d&&d.scrollTop){return d.scrollTop}if(window.pageYOffset){return window.pageYOffset}return 0},attachEvent:function(a,b,d){if(a.addEventListener){return a.addEventListener(b,d,false)}if(a.attachEvent){return a.attachEvent("on"+b,d)}},end:function(e){if(window.event){window.event.cancelBubble=true;window.event.returnValue=false;return}if(e.preventDefault&&e.stopPropagation){e.preventDefault();e.stopPropagation()}},scroll:function(d){i=window.innerHeight||document.documentElement.clientHeight;h=document.body.scrollHeight;a=Scroller.scrollTop();if(d>a){if(h-d>i){a+=Math.ceil((d-a)/Scroller.speed)}else{a+=Math.ceil((d-a-(h-d))/Scroller.speed)}}else{a=a+(d-a)/Scroller.speed}window.scrollTo(0,a);if(a==d||Scroller.offsetTop==a){clearInterval(Scroller.interval)}Scroller.offsetTop=a},init:function(){Scroller.attachEvent(window,"load",Scroller.load)},load:function(){a=document.getElementsByTagName("a");Scroller.end(this);window.onscroll;for(i=0;i<a.length;i++){l=a[i];d=location.pathname;if(l.href&&l.href.indexOf("#")!=-1&&(l.pathname==d||"/"+l.pathname==d)){Scroller.attachEvent(l,"click",Scroller.end);l.onclick=function(){Scroller.end(this);l=this.hash.substr(1);a=document.getElementsByTagName("a");for(i=0;i<a.length;i++){if(a[i].name==l){clearInterval(Scroller.interval);Scroller.interval=setInterval("Scroller.scroll("+Scroller.offsetParent(a[i])+")",10)}}}}}}};Scroller.init()

Answer 3

前端的一切XXXXXX都是紙老虎！ ^_^

Answer 4

比较经典的Script Encoder解密

Answer 5

.replace(/</g,"&lt;").replace(/>/g,"&gt;")
不过在这里好象不需要用这个刚才我复制回来解的时候他多了好多空格符！！倒，不知道是我编辑器的问题还是咋回事我也用了Script Encoder解密得到结果却含有许多无用的空格符和其他字符
所以就以为他有三种加密的
