js怎么解密,js解密工具js怎么查看这些代码麻烦给解决一下

首先你的加密后的代码有误,无法执行,应将return(c35?String.fromCharCode(c+29):

修改为return(ca?"":e(parseInt(c/a)))+((c=c%a)35?String.fromCharCode(c+29):

c和35之间的部分你没复制出来

这种加密的算法的解密方法很简单

html

body

div?id="test"/div

script?type="text/javascript"

document.getElementById('test').innerHTML?=?将需要破解的代码全部复制过来,注意你原来的代码不对,请通过替换先将上面说的那个错误改正

/script

/body

/html

将上面的代码保存成html文件,打开此文件即可看到加密前的内容,由于你的问题解密后是广告语,所以不在此处给出,自己试一下

功能强大的JS加密库-CryptoJS

CryptoJS是JavaScript的一个加解密库集合,可以说平时开发中需要用到的加解密方法,它这里都包含了

1、MD5加密,这是一种不可逆的加密

2、SHA-1加密,是现有 SHA 哈希函数中最成熟的,它用于各种安全应用程序和协议

3、SHA-2加密,不像 SHA-1 那样广泛使用,尽管它似乎提供了更好的安全性

4、AES加解密, 是美国联邦信息处理标准 (FIPS)提出的高级加密标准

5、DES加解密, DES 是以前占主导地位的加密算法,并作为官方联邦信息处理标准 (FIPS) 发布,由于密钥大小较小,DES 现在被认为是不安全的

6、转Base64

好了常用的加解密方法就介绍到这了

如何解密js

当你在浏览网页时,看到一个很漂亮的特效,你查看源代码时看到的是一队乱码,那多扫兴呀!根据本人的研究,总结出了三种解密方法,与大家分享!!

方法一:

有一种加密的办法是采用javascript的escape()函数,把某些符号、汉字等变成乱码,以达到迷惑人的目的。解密这种代码的办法是采用其反函数加以还原。下面是一个经过加密的例子:

HTML

SCRIPT LANGUAGE="Javascript"

var Words ="%3Chtml%3E%3Cbody%20bgcolor%3D%22red%22%3E%3Cp%3E%u8FD9%u662F%u4F8B%u5B50%uFF01%uFF01%uFF1A%uFF09%3C/p%3E%3C/body%3E%3C/html%3E"

var NewWords;

NewWords = unescape(Words);

document.write(NewWords)

/SCRIPT

BODY

/BODY

/HTML

这种文件最好解密,一看就明白,关键是unescape()函数起了还原源代码的作用。要想看到加密前的代码是什么样子,可以用下面的办法:

HTMLSCRIPT LANGUAGE="Javascript"

var Words ="%3Chtml%3E%3Cbody%20bgcolor%3D%22red%22%3E%3Cp%3E%u8FD9%u662F%u4F8B%u5B50%uFF01%uFF01%uFF1A%uFF09%3C/p%3E%3C/body%3E%3C/html%3E"

var NewWords;

NewWords = unescape(Words);

NewWords=NewWords.toString();

function password(){

document.pw.txtpw.value=NewWords;

}

/SCRIPT

BODY

form name=pw

input type=button onclick="password()" value="解密"

br

textarea name="txtpw" cols="100" rows="100"/textarea

/form

/BODY

/HTML

方法二:

有一个软件叫HTMLEncrypt.exe,它就是把源代码进行加密的软件,这个软件的加密的原理是把字符转换。下面的例子是一个分帧的页面:

htmlheadscript

function Carbosoft( s ) { var sRet=""; for(j=0; j s.length; j++ ){ var n= s.charCodeAt(j); if (n=8364) {n = 128;} sRet += String.fromCharCode( n - 3 ); } return( sRet ); }

var sJsCmds ="" +

"?kwpoA?khdgA?phwd#kwws0htxly@%Frqwhqw0W|sh%#frqwhqw@%wh{w2kwpo#fkduvhw@lvr0;;804%A?wlwohAZHOFRPH?2wlwohA?phwd#qdph@%JHQHUDWRU%#frqwhqw@%Plfurvriw#IurqwSdjh#613%A?phwd#qdph@%Plfurvriw#Wkhph%#frqwhqw@%qrqh/#ghidxow%A?phwd#qdph@%Plfurvriw#Erughu%#frqwhqw@%qrqh/#ghidxow%A?2khdgA?iudphvhw#erughu@%3%#iudpherughu@%3%#urzv@%-/93%A##?iudph#qdph@%pdlq%#vuf@%xs1kwp%#vfuroolqj@%dxwr%A##?iudph#qdph@%rqolqh%#vuf@%grzq1kwp%#vfuroolqj@%qr%#qruhvl}h#wdujhw@%beodqn%A##?qriudphvA##?erg|A##?sAWklv#sdjh#xvhv#iudphv/#exw#|rxu#eurzvhu#grhvq*w#vxssruw#wkhp1#?2sA##?2erg|A##?2qriudphvA?2iudphvhwA?2kwpoA?irqw#froru@%33333%A?s#doljq@%fhqwhu%A?vpdooA?irqw#idfh@%Wdkrpd%AWklv#iloh#zdv#hqfu|swhg#xvlqj#dq#xquhjlvwhuhg#yhuvlrq#ri#?d#kuhi@%kwws=22fduer{1wkhgqv1qhw2kwpohqfu|sw1kwp%AKWPO#Hqfu|sw#y413?2dA1?2irqwA?2vpdooA?2sA" +

"";

var s= Carbosoft( sJsCmds);

document.write (s);

/script

/headbody/body/html

从上面可以看出,浏览器解释这写代码前,进行了还原,从而可以得到破解的方法如下:

script

function Carbosoft( s ) { var sRet=""; for(j=0; j s.length; j++ ){ var n= s.charCodeAt(j); if (n=8364) {n = 128;} sRet += String.fromCharCode( n - 3 ); } return( sRet ); }

var sJsCmds ="" +

"?kwpoA?khdgA?phwd#kwws0htxly@%Frqwhqw0W|sh%#frqwhqw@%wh{w2kwpo#fkduvhw@lvr0;;804%A?wlwohAZHOFRPH?2wlwohA?phwd#qdph@%JHQHUDWRU%#frqwhqw@%Plfurvriw#IurqwSdjh#613%A?phwd#qdph@%Plfurvriw#Wkhph%#frqwhqw@%qrqh/#ghidxow%A?phwd#qdph@%Plfurvriw#Erughu%#frqwhqw@%qrqh/#ghidxow%A?2khdgA?iudphvhw#erughu@%3%#iudpherughu@%3%#urzv@%-/93%A##?iudph#qdph@%pdlq%#vuf@%xs1kwp%#vfuroolqj@%dxwr%A##?iudph#qdph@%rqolqh%#vuf@%grzq1kwp%#vfuroolqj@%qr%#qruhvl}h#wdujhw@%beodqn%A##?qriudphvA##?erg|A##?sAWklv#sdjh#xvhv#iudphv/#exw#|rxu#eurzvhu#grhvq*w#vxssruw#wkhp1#?2sA##?2erg|A##?2qriudphvA?2iudphvhwA?2kwpoA?irqw#froru@%33333%A?s#doljq@%fhqwhu%A?vpdooA?irqw#idfh@%Wdkrpd%AWklv#iloh#zdv#hqfu|swhg#xvlqj#dq#xquhjlvwhuhg#yhuvlrq#ri#?d#kuhi@%kwws=22fduer{1wkhgqv1qhw2kwpohqfu|sw1kwp%AKWPO#Hqfu|sw#y413?2dA1?2irqwA?2vpdooA?2sA" +

"";

var s= Carbosoft( sJsCmds);

/script

form name=qq

textarea name=ww cols=100 rows=10/textarea

input onclick='ww.value=s' type=button value="解密"

/form

方法三:

有一种加密方法是每行单独加密,还原起来比较复杂。看一个加密过的原文:

HTML

BODY

SCRIPT LANGUAGE="JavaScript"

function Decode() {

d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}

/SCRIPT

SCRIPT LANGUAGE="JavaScript"

function d (enc) {document.write(codeIt(key,enc));}

var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%\'()*+,-.\/:;=?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}

/SCRIPT

SCRIPT LANGUAGE="JavaScript"

Decode();

/SCRIPT

/BODY

/HTML

还原的时候,也必须每行单独解密,用下面的方法可以看到源代码:

HTML

BODY

SCRIPT LANGUAGE="JavaScript"

function Decode() {

d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}

/SCRIPT

SCRIPT LANGUAGE="JavaScript"

function d (enc) {alert(codeIt(key,enc));}

var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%\'()*+,-.\/:;=?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}

/SCRIPT

SCRIPT LANGUAGE="JavaScript"

Decode();

/SCRIPT

/BODY

/HTML

哈哈!!:=)是不是很精彩!!
