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！！: b" m& m& N9 V* F, e
+ B+ Q' |7 h) T9 g. R6 `1 _8 w8 u
! f. @$ f9 j" O- g9 Y3 G' k( X方法一：
( y8 P0 T, {) s- g* R! _$ M# q! H! h# D* C( \0 _) y% c+ Y' { ^" H
0 @) ~, L" u5 O/ N6 S8 c 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：
- X( p# r6 b0 g+ a+ ]) H+ S2 G/ u7 i' |) ~1 U
<HTML>, B/ l7 Q6 J- N( I9 Y- w
<SCRIPT LANGUAGE="javascript">+ b6 f. L; ~$ I+ F

8 z' O! F* d* L) Ivar NewWords;
( X, q# z/ ]0 H# ?' c& u. j$ bNewWords = unescape(Words);; E# u; Z* j% Z. x: W
document.write(NewWords)/ {5 M8 [, a3 F8 o e

</HTML>7 V) N6 F: Y" v/ q s1 b: R
7 K, _6 O7 S: f+ Y x0 i5 k+ i
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：

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成Unicode代码。下面的例子是一个分帧的页面：& B8 a3 B1 P6 u( c: j

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 ); }

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：

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：- n0 Q/ b0 u# S2 h5 ^& t& A
