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！！

0 T& M! e* P4 K9 b# n
方法一：
- R; J% W5 Q( V% |0 R' g
3 Z. O$ v1 F. S0 X5 N
　　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：% s4 B& Y- o1 R; D
4 H! S- J" J6 P8 s0 f
<HTML>1 u) Q* g" H) F
<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;  G3 D; g. {$ d6 ?& L' c1 h
NewWords = unescape(Words);, b8 r8 K+ g: j
document.write(NewWords)7 w& N3 f( g  b. t1 ?
</SCRIPT>
<BODY>
</BODY>
</HTML>* k6 @. j9 {- W& E. ?
3 b1 Q) q; y$ }  t
　　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：
/ @+ e# f) ]0 f0 x
<HTML><SCRIPT LANGUAGE="javascript">1 v% R* S3 o  `% j& f% s* @
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". p6 ?& {. Q0 P1 c. w
var NewWords;+ _# |6 N8 _+ K8 F
NewWords = unescape(Words);
NewWords=NewWords.toString();& b7 ^% P) ]" n
function password(){' E  t: j/ q- A5 B2 O( G
document.pw.txtpw.value=NewWords;& y1 [3 D8 w" H3 E' x
}8 `; r! ~8 ?! m2 c' h
</SCRIPT>" A# ~) f/ x: n; [( w1 j( F
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">0 R' O% O- f0 Z
<br>7 p: e( c" z& ^; P( }  D, C
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>" W0 f3 J6 S7 s  e  O3 g" I
</BODY>4 a" t4 p: m  [0 C# `( m6 a# c
</HTML>2 |5 e, r4 H6 H8 L. h0 B
8 J; o* W0 I' T. f. |
方法二：
. L9 r! R& B: G! e! I/ T2 E
　　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：
6 |+ Y- p: i' e. P7 @
<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 ); }$ @: }6 r/ c4 f& F6 N
var sJsCmds ="" +: Q6 Z( e: ?0 q' b5 P
"?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" +
"";1 j9 y/ E" x, W8 H5 X- z/ [
var s= Carbosoft( sJsCmds);
document.write (s);% P, S- H6 F- ?: P- X$ ]
</script>+ O- W, Z& m. |0 i9 N
</head><body></body></html>* c6 t5 X, H* ^3 J% S& v

　　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：, s2 U3 |% J4 N8 G& `

<script>3 x& G) {7 Z' e, e6 }
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 ); }, o. v6 F: G4 j% d
var sJsCmds ="" +/ d( l, \. D/ J* q) b  s
"?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" +; r# W% d/ W( u1 ]" I9 S

var s= Carbosoft( sJsCmds);
</script>
<form name=qq>

<input onclick='ww.value=s' type=button value="解密">
</form>/ N: [0 }. j8 G+ V7 j! ]
' |2 @% J- W. e0 S! Z( k
' i6 T& e# ?7 W% ?9 z
方法三：# r+ x' [: _& J
4 W! f' g8 n, D2 a# r
　　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：. S8 z8 v2 Q" |" J
! a5 J3 ~* |) F$ K5 [1 v
<HTML>
<BODY>; n4 i) n5 \& ]/ Y3 w
<SCRIPT LANGUAGE="javascript">

</SCRIPT>* D3 w/ V, Y. R' }8 ]% D7 a
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}$ |0 U9 |1 y2 T: X5 O3 c7 o
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;}1 `6 w+ `1 A8 q7 c2 D* }
</SCRIPT>/ ^1 ^# B6 F; ~, }1 d2 K
<SCRIPT LANGUAGE="javascript">
Decode();, z3 G. [% a& r# |
</SCRIPT>
</BODY>
</HTML>! G* p0 V7 Y8 O+ }
% f4 q: n3 ^3 G- }% ]
　　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：  `, x# V( `* F1 R

<HTML>
<BODY>; e) R% E. q; C+ o- u% m
<SCRIPT LANGUAGE="javascript">  {+ R* u. x9 U9 ]5 p+ @7 h
function Decode() {

</SCRIPT>8 ^9 x2 c2 ^& v4 b2 i: p
<SCRIPT LANGUAGE="javascript">6 a2 n% V/ r+ U0 n
function d (enc) {alert(codeIt(key,enc));}3 o. V6 H7 l; H! R
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>
</BODY>" X# a; E$ c* U8 ^6 d0 J
</HTML>

　　哈哈！！:=)是不是很精彩！！
