网页制作中页面的加密和破解

网页加密, 网页破解

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！！

方法一：0 {6 d- |4 S7 Y, H) ^8 Z

　　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>& Y* r. I' s6 `$ f2 t1 n
<SCRIPT LANGUAGE="javascript">8 _5 P# J' n/ Z7 e( t
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"4 w; v" Q2 D$ z8 U
var NewWords;/ |7 g$ H2 k' _( G! S9 |
NewWords = unescape(Words);# x6 k; G& d( R6 B% l" N
document.write(NewWords)( }1 @6 I! |+ I# @% h; H
</SCRIPT>, O6 O% C) u6 B, n: ]
<BODY>
</BODY>
</HTML>- |, ]" d( e8 Z6 s/ E6 {

　　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：
% Z2 r5 [6 N7 t) l
<HTML><SCRIPT LANGUAGE="javascript">6 `+ g% R, h" y: D# S4 |4 f: \; q
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"9 C2 q& P, U! s! H$ u
var NewWords;
NewWords = unescape(Words);% ~4 }$ ]( _% C% a6 ^% i
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>
<BODY>% q# N7 w" M' ~! ~9 b# K( C
<form name=pw>: B/ p) j2 p) y. o+ b+ J: W7 e
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>! Q1 Z: u0 p" h: C) \9 N  h
</form>
</BODY>
</HTML>; h( \1 x, a7 R! T
. D) B, q1 P1 Q- m- ~, f
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：' L0 j" w' t. u& I% m/ z1 V

<html><head><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 ); }% i7 I0 d8 _1 b6 ]
var sJsCmds ="" +$ j& g! K1 y/ E' h

"";
var s= Carbosoft( sJsCmds);
document.write (s);6 g/ `5 v% \7 P) F
</script>
</head><body></body></html>* J$ ?% ^4 w- }
: [: l3 Z- s, b% J3 C7 u9 }* V
　　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：+ |0 m  o+ ^& J3 ^& C
3 k* O* ^  Z% f& J. [  f- P
<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 ); }1 H( O7 K" v* F0 [
var sJsCmds ="" +

　　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：

</SCRIPT>! h/ u6 W/ c: z* J+ v

</SCRIPT>
</BODY>6 \  ~% E8 j1 J9 p7 K' a  g8 `; x1 C

　　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：0 i$ ~, R1 H, y4 G3 |8 S

<HTML>4 h2 ]) l' p" E# B* j

<SCRIPT LANGUAGE="javascript">+ d' n# H' X1 z3 q9 h; c

　　哈哈！！:=)是不是很精彩！！
