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！！: ^( R0 w" }: P6 ?+ G- z) U
2 b5 g* q1 N9 `$ D4 T
- A. J6 k9 N$ L' H: l% \
方法一：; ]6 ]+ m0 K% I) w5 b& d  d
  V) U& i6 l, `; c- g; F% b( M

　　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：8 d+ d" K; j4 {% ^' X/ O
+ {3 I- ~& F3 J
<HTML>
<SCRIPT LANGUAGE="javascript">% m; ?% c! P% B1 ]" J/ k$ P
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"$ q9 U4 g( W# a1 i4 b$ Q
var NewWords;
NewWords = unescape(Words);( k- V) O, z) {* |
document.write(NewWords). J# K  \& d0 H' A% H: F% W  G
</SCRIPT>
<BODY>
</BODY>
</HTML>& y+ [) Y! D. h/ F
- j3 R- x) b# q0 u6 z. _5 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">1 W( |! w. u! @- N% T+ y
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);- c* v- F: _# Y+ ~' u
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;  X) g- _, N( }8 h$ K$ d
}
</SCRIPT>- I6 H# Q, ?" F6 G' D0 Y6 d5 ^
<BODY>9 J& _" N( e% b/ F5 @
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>( d/ r' r, E$ n6 b. u& h. L
<textarea name="txtpw" cols="100" rows="100"></textarea># l- K3 r3 U- q. E
</form>
</BODY>8 J+ G8 z0 V- I9 C. t& n; z  r
</HTML>8 L/ ~* T" T) q* y$ }/ n1 ]6 z

方法二：
/ I, O- o7 G! ~+ b/ b
　　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 k. \) H/ c4 {8 H; v% S
<html><head><script>. B: L4 b; u+ X1 G) m1 J
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" +
"";
var s= Carbosoft( sJsCmds);
document.write (s);( m9 I6 Z& |8 ]) x
</script>6 D* ^) ^) r9 [: H( Z* {2 m/ T
</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：
" t2 W1 p7 I3 U
<script>3 q6 X" P( E. `6 R- J
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 ); }7 ^! ?  Z- i, y- o7 J2 E& ~$ W. _
var sJsCmds ="" +! b6 R$ }& F& H' A) z9 N# g
"?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" +- f2 n& k; n1 y' W7 L
"";
var s= Carbosoft( sJsCmds);
</script>
<form name=qq>* Q# }# \; s* [' T( x- r1 t
<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">
</form>
7 z2 n+ C' V2 ]) w' E
/ _* R( _8 |  A
方法三：
; {- c% I; V, ^# e- M; 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：, t; ~, e- g, L. |( {0 ?7 i

<HTML>
<BODY>$ ]& W, q$ B# T' i& [6 ~% @
<SCRIPT LANGUAGE="javascript">
function Decode() {# t+ |: ?: l& ~
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}8 B% z6 k- n, P. A3 j2 V! l
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}* F; e, K# n* s8 [& R4 i  Y/ |, L
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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>6 j8 O  x2 Z; G: j) \: N; a
<SCRIPT LANGUAGE="javascript">0 j+ U$ V) L+ }) k& @4 S2 a% }
Decode();
</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：' k; `2 G- E( U
% T$ ?% A- c5 ~, q5 |1 d3 L
<HTML>( a0 ?2 h/ I! F/ ^' y
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>3 G: {0 T3 k- G
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}# y# q3 [& D3 A9 A+ j8 m9 D! h0 M
</SCRIPT>$ P0 h/ |* ~- E! c5 j! n( o
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>
</BODY>
</HTML>+ S) f  z3 p* q" E4 |4 [. z. P

　　哈哈！！:=)是不是很精彩！！
