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！！3 A7 q+ M7 f0 y5 q' O

方法一：6 E1 p% x  f7 R7 i- k# v4 d

% w$ u* P9 i# U$ _  L
　　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：' c. u+ R/ m$ c/ c! T+ N
8 R: E$ `% P) c# p, @7 n6 }
<HTML>7 `7 }( l7 {+ ?7 l; J3 N
<SCRIPT LANGUAGE="javascript">" [2 f3 ?8 ?/ P9 f. f# S# 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"
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>
<BODY>
</BODY>/ Q* G0 `+ f* p8 Y
</HTML>; p2 d+ |9 w( c. p
. `* c# M' x$ d9 R4 g
　　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：. i2 r5 C$ A% L# m) M% @! w; A' g; }
% E+ u7 x7 Q/ R( _3 p  B3 i# ?
<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;6 H) U9 J8 D) q/ {% E( k
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){% L0 f  `' E) v/ E) U( `
document.pw.txtpw.value=NewWords;- p9 t/ `# u0 q* t# s5 d( V9 p
}
</SCRIPT>
<BODY>, V$ p1 {' h2 u6 f) f0 A0 i
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>7 R' G( S! P9 G; d/ h
</BODY>
</HTML>/ @# Y( M' z$ Q0 K
: j3 d, ~7 }' H8 J. m0 `3 I
方法二：5 u9 N# Q, N5 [/ W
9 L* l9 _4 _  p6 D9 O3 Y7 w" f
　　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：( s2 M- P$ ^5 e7 Q) }

<html><head><script>$ l/ q$ ^6 v; Q! K& {( k! P
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" +- J8 n1 e/ i2 b/ c) m0 u9 w, d

var s= Carbosoft( sJsCmds);
document.write (s);& s% g9 j- H1 t2 K% M5 h
</script>
</head><body></body></html>; g1 t2 c/ D6 U, T4 Q
- A, J9 s' {. T. A' I% A
　　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：2 ]/ Z+ ^+ M5 J; C

<script>* A+ X4 w+ X' j* g9 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 ); }! b) ]; X- F1 Q6 Z9 ]
var sJsCmds ="" +2 v$ y( k) y$ D+ M
"?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" +

　　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：
5 R+ K4 n) Q4 x% `/ W
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">9 I0 p6 [. _( S2 w# W3 Y
function Decode() {+ T( {2 s, E8 N5 f8 I) W4 U

</SCRIPT>
<SCRIPT LANGUAGE="javascript">- \! n9 C2 [& [) u" _9 E8 ]
function d (enc) {document.write(codeIt(key,enc));}% b0 S+ f: H) C5 I: s
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
</SCRIPT>& m, O# b# F. H
<SCRIPT LANGUAGE="javascript">
Decode();7 E* C' Q' ?/ Z; m+ G: I* k$ U. J& _
</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：2 g4 n, p* b+ i: K0 ^, X! p" H
- X5 Q3 A" \- l/ D
<HTML>3 D* i0 g8 B5 L0 L5 X1 z3 l

　　哈哈！！:=)是不是很精彩！！
