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！！
% u9 M/ i( B1 J! N) J. o( G' N4 C2 W
! M, F5 Y0 l) D( j2 U1 ^# Z& ^0 z2 g6 k
方法一： ]% K5 Z. R* s* B% q
+ Y. W. B4 |+ r
% Q5 l0 R! G2 f) j+ f+ g 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：
/ p- j5 T5 A! J5 q/ ]; f; D+ ^& ~- e2 p5 J: z
<HTML>4 W- m3 \9 C5 L& Y
<SCRIPT LANGUAGE="javascript">+ i& ~* [' n1 e- M5 O8 \( v, [$ e
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"
% b3 `7 N1 {& x7 \& Y: N D% E$ w3 cvar NewWords;
& w7 m7 Y* `+ p, H/ w8 nNewWords = unescape(Words);
. g# Q8 x$ I2 e* s0 Z9 Udocument.write(NewWords)% {% D4 t/ f3 W/ @5 H; j
</SCRIPT>
% ?2 n9 q. l( `1 K( s9 c* p' [<BODY>
) h. u& r! d6 R7 \' `& E- t5 {& M</BODY>) I5 Z, S/ h; ^% _2 a8 _! n9 X
</HTML>) x0 v1 B7 b4 C" q; a
$ ?* C* ~8 o. Y/ e6 h 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：! b# Y4 J: W2 f6 u# ]6 Y' n4 O7 ^5 p
' l; h' Z+ r$ R) b' b<HTML><SCRIPT LANGUAGE="javascript"> u9 T+ U" e/ H }; X+ m$ @) z

( }( _ n1 t4 e( ?% o3 Avar NewWords;3 q i* Z9 e$ C7 I6 ^; M
NewWords = unescape(Words);. t. ?6 [. `. X( M+ w) ]
NewWords=NewWords.toString();9 k5 k* B6 D9 Y& H% V: }
function password(){

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成Unicode代码。下面的例子是一个分帧的页面：- ` m& s, t( r8 F! f% r% E
2 _6 E% s& }# r0 h! G% l! f& _2 n<html><head><script>
- ^) T, L. Z% C' }6 Ufunction 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：6 A1 z# D/ Z: X1 M& ]1 u; z
