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：

  |1 R7 C% f$ Z9 q6 j4 F+ v8 r
　　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>0 q, H9 W8 R$ j+ \' t/ _( P; g
<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;7 D  y, m0 B% C" v
NewWords = unescape(Words);
document.write(NewWords); K: d$ e! Q, ~! B6 K  C1 W9 g
</SCRIPT>
<BODY>9 C) ]8 n+ |" V
</BODY>: {' o: C1 `9 r* u
</HTML>1 \# \# }- ]* |# ?( r
2 l0 N1 [' j, p
　　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：

<HTML><SCRIPT LANGUAGE="javascript"># M6 ?6 R) o6 h+ v- z# I8 f6 H
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 _# G/ B3 `+ U+ I9 J( t4 a# G# V
var NewWords;
NewWords = unescape(Words);
NewWords=NewWords.toString();, ]" A3 |$ p' a/ ^* G5 Q* a) B8 d# G/ U
function password(){* [# e- f6 p3 H( P) c. y! I
document.pw.txtpw.value=NewWords;2 \+ @  D( G8 H" P' W
}2 g. g4 b, z" a6 K
</SCRIPT>
<BODY>$ I" G# j- U  i  v* t
<form name=pw># D5 l5 ]/ @& J- ^% Z. e
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea># D' b+ ]6 _) H: T$ r
</form>
</BODY>
</HTML>

方法二：1 g, i( j0 N# I; L# z. \- L

　　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：4 O" t. N) H& N) @

<html><head><script>) z3 {5 W8 `& J! Y4 i
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" +
"";- _# J6 a6 ^% Y. t7 N4 e. l8 s& B
var s= Carbosoft( sJsCmds);
document.write (s);2 F" o7 B7 I* j0 n( M% V
</script>
</head><body></body></html>8 r' j  S4 l( u2 u" L! v+ u3 ], r4 H

　　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>% t/ [& V/ W; O9 |1 F
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 ); }6 N6 G! X9 q# |* D$ r+ M, \
var sJsCmds ="" +. G7 d5 L$ Z% ?- T* N$ O
"?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" +

方法三：
8 {; j8 G7 [& Q9 V8 }
　　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：

<HTML>
<BODY># r8 e1 ~3 L1 D1 G  \0 m3 ]
<SCRIPT LANGUAGE="javascript">
function Decode() {" B9 E& v( _  O  ^" }
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;}0 E: Z2 w- I9 X5 H, b7 ^, m6 _
</SCRIPT>
<SCRIPT LANGUAGE="javascript">( S/ b) G8 E* X5 ?: u

H5 w* w3 }$ d
</SCRIPT>1 W1 ^, L5 r3 u$ b2 h, |
<SCRIPT LANGUAGE="javascript">3 M6 @% E6 j. F' q6 u4 ?; K1 }+ y

</SCRIPT>5 A5 `9 B$ s% N" h7 U6 o8 K
</BODY>
</HTML>) G: O0 d% v' ?7 G# z) E
/ G1 `' l8 s- Z2 u
　　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：
: D7 B- K% V2 Y
<HTML>. C/ Q# |" g& x$ {( s4 v2 v
<BODY>) t4 I1 w( e$ Z2 L  E  u
<SCRIPT LANGUAGE="javascript">

</SCRIPT>; k: a: G4 }6 t9 [+ ^
<SCRIPT LANGUAGE="javascript">6 G# L' A& w7 i. d, l
function d (enc) {alert(codeIt(key,enc));}
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>5 P8 D+ f1 @2 A  r9 E, ?: ^  ^
<SCRIPT LANGUAGE="javascript">

　　哈哈！！:=)是不是很精彩！！
