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！！

6 p- s. `1 K2 B7 ]9 x0 m
方法一：

1 a- ~# i' p! l* d/ E5 R( I1 n; a
　　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>, N5 I0 c3 X& b7 b
<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": ~! H& L# X5 s
var NewWords;
NewWords = unescape(Words);' F: o, }: X  ]' e- W1 J
document.write(NewWords). \& U+ T; s, M- O7 u) D3 k, [
</SCRIPT>8 u% {; q! A0 m& Q- O) R
<BODY>
</BODY>
</HTML>) _/ G+ _2 o, [1 V) n, [, z' r; o
5 ?0 y8 Q1 r& R! S2 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：
5 {1 N9 i7 \: ]  d* z' m2 B/ f9 Q
<HTML><SCRIPT LANGUAGE="javascript">6 m( A  _; j7 @: j5 ^+ p1 k
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;! c; a! b1 H! s4 ^: m
NewWords = unescape(Words);2 k" I/ M- t+ N: P4 E% {
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;( a2 F7 ?8 M6 s9 B; @
}
</SCRIPT>& u. |: e6 \8 X/ e- L, q, m7 E, n
<BODY>
<form name=pw>5 I: T. M$ c# t+ s& @% n1 \
<input type=button onclick="password()" value="解密">
<br>, Y* [# ~+ X3 k+ w' N; T) P
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>8 I, W* d; O4 o4 D8 k/ F
</BODY>& t( t1 W) t  ~: |- u( e4 W3 _3 Z9 U
</HTML>

方法二：4 n9 q% F8 C4 |6 k3 T
7 ~: O7 x$ Q6 K9 x- G0 j  _; z" n
　　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：- Q9 A% b6 t5 W9 X  C5 E

<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 ); }9 g" J* K! C% o" {
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" +
"";
var s= Carbosoft( sJsCmds);( Y% E+ R, e, ?3 E% y
document.write (s);
</script>, X/ ]0 S: _2 D/ x1 G
</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：# h) w( ~4 n. P
: s7 l6 s4 V# a& W/ L5 K
<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 ); }8 d* C( q* Y7 m; i! m. P8 t
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" +.

<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">' @) ?2 S7 [) l" r* p4 ^7 l& w
</form>

方法三：# ~) g5 C5 N( [- {& g# x

　　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>; T. s0 V( A3 Y6 n% y( B
<SCRIPT LANGUAGE="javascript">8 o) X  G" ^$ o6 i
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>1 e1 |8 l* C8 m3 K# _
<SCRIPT LANGUAGE="javascript">% w8 u) ^5 P- R2 ?7 x
function d (enc) {document.write(codeIt(key,enc));}* S: z4 H  b6 D' e) s* y
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}8 B  O; [, N1 s
</SCRIPT>
<SCRIPT LANGUAGE="javascript">3 q5 e- j! i5 i
Decode();
</SCRIPT>; Z( T* a% R- k( p2 O! l
</BODY>0 ]  w6 m& b( R$ a% U4 ?  t
</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：
  }4 Y1 u9 a' p; x: [% [
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}  i, I- c. h& X
</SCRIPT>
<SCRIPT LANGUAGE="javascript">' v1 N" u$ x  @+ B3 e
function d (enc) {alert(codeIt(key,enc));}) f! V6 u- s9 y9 F0 |# W1 [
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">) u0 a  e# q7 x: ^* U- g) |+ }3 Z
Decode();  p2 P6 |" W4 V+ D2 X* ]
</SCRIPT>9 r% ?7 b6 j& A" I$ U
</BODY>1 E, h, K* }5 Z+ ]4 K) z
</HTML>! v8 Z0 V3 q* x! Y. v0 M

　　哈哈！！:=)是不是很精彩！！
