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！！
% L2 H% J; A) \- F

方法一：* ]0 B0 t, A$ R
1 R: q0 h/ E9 \$ N# G( O0 E

　　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：
- j/ O- i1 l: x: d% f; G
<HTML>' Q6 q3 u8 s% m' {5 t8 r; Z
<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"7 ]8 D3 t5 I" O; Q
var NewWords;# {- W: E* W) M! c# B; W
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>
<BODY>
</BODY>: N2 N3 V: ]7 ]# ~6 T% c
</HTML>
6 {2 y. ~# x6 O: g1 u- f
　　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：; N5 U3 |0 W" ~/ \- j8 I& ~# R6 e

<HTML><SCRIPT LANGUAGE="javascript">& \! L  g8 {& z: b% R3 q1 R2 T* o
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"/ W0 k& C  I0 P+ s5 A# j5 }+ J
var NewWords;& d! [/ D, o, S
NewWords = unescape(Words);
NewWords=NewWords.toString();4 O& y' m9 U. g' ~/ K
function password(){
document.pw.txtpw.value=NewWords;
}0 y; `+ k) w1 f' p( v5 ?9 U
</SCRIPT>
<BODY>5 y- f# a& A/ W2 Z5 J5 ~$ |% z. L- U
<form name=pw>2 _1 T( I8 K3 n
<input type=button onclick="password()" value="解密">0 u  R2 n3 D) r. i
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>4 ?- L. G; H. A3 X1 x3 O' g. S6 I
</form>
</BODY>
</HTML>

方法二：: `* [+ U% o9 x7 v, n; ]; N2 @
. y; b, U0 W: ?
　　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：1 g( R# R. i8 I5 U
7 i  a+ o" g. I, s* I
<html><head><script>( r2 j% h& Z( m# X/ X
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;;8<04%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" +  n8 M& }9 o0 J7 i!

"";
var s= Carbosoft( sJsCmds);0 I& e. F1 n( e4 r' [) K. w
document.write (s);  \# }2 r; b$ O4 |
</script>) s; g. [, d5 |& u4 i) f  L
</head><body></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 ); }( f/ S3 Z4 d' o2 `' Q" U$ C& g
var sJsCmds ="" +& b* W3 P" g7 _: @- S) U4 u

方法三：6 M9 R4 s6 [  l+ _- H# @

　　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：
: P3 k+ k3 `9 x8 n: H
<HTML>
<BODY>. O2 k. E3 y, u& N* S
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}) R: `6 v+ {* a9 I. Q
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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">+ a  A, Q/ I$ i* P& a
Decode();
</SCRIPT>2 Q1 p& Z5 W6 a; r2 [0 _8 b# z7 N0 c
</BODY># p7 K- @/ O7 U5 j1 T4 u" i
</HTML>/ F0 g; ~  Z8 M; `/ U" K7 ]' {

　　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() {8 `  r3 M( F2 |- q
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>8 h2 p/ n5 [# |( P( W
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}# J- c+ g& N- E: e
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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>7 X9 O1 I9 m0 r4 P+ K4 I, F* Q
<SCRIPT LANGUAGE="javascript">% ?# y4 p, D6 ^) k" [3 X$ ~
Decode();
</SCRIPT>- \) q, [8 B: M- O* u1 R
</BODY>) \0 M1 S* k* e! f( t' d" r; C

　　哈哈！！:=)是不是很精彩！！
