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！！2 W, d  u! t+ Z8 }" b5 ?& s

+ P( z% u7 o4 P- t* Y
方法一：

　　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：
+ P2 O4 N# o* }8 }9 _3 e
<HTML>- `; {9 N1 v9 U" J; t; Q7 ~, ]1 j2 J
<SCRIPT LANGUAGE="javascript">1 ]) ?. C1 ~, P% t) ^1 ^
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);; i0 j3 U1 `0 A% d$ D
document.write(NewWords)  m3 T1 ^$ }. k: A0 O/ f- L
</SCRIPT>. V8 t$ L2 k% P" P; ^
<BODY>
</BODY>
</HTML>: h% g- y2 O6 o" _0 [

　　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：1 N  X* V! S) S; Y' Z9 Z) o

<HTML><SCRIPT LANGUAGE="javascript">) I, b9 T8 @0 B2 Y4 O- }
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);
NewWords=NewWords.toString();8 Q# t" X2 [% W" ]8 c% \9 U+ J
function password(){
document.pw.txtpw.value=NewWords;+ O0 t! ^" I% L' Z; `1 n
}1 ~9 s4 h( U1 r5 E% Q8 O# A& G
</SCRIPT>2 O. g+ m  @& q  |
<BODY># @, E( Y9 }5 o3 P
<form name=pw>( V* E% z, R& Y% b4 s* i, \; p
<input type=button onclick="password()" value="解密">8 ], ]" W! X1 m5 l
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>! g; a3 T  j% A% A
</form>
</BODY>
</HTML>

方法二：

　　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：

<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 ); }
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" +; j( j% p3 G; x5 R, Y, V
"";
var s= Carbosoft( sJsCmds);5 s) D7 ?  p% {- O/ ^+ Y6 l9 I

</script>7 m4 ]: w/ V: R# G" b: [0 u0 @
</head><body></body></html>
# y% m+ @' c) m! L
　　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 V0 W2 S' V* V+ w  U* B) v
# T: \* [* I- Z! q6 Q" R2 ^
<script>+ |& y* O. X9 C* K# m
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" +$ ?+ W& Z/ R. o( ?( X7 M

方法三：
! c( m3 G7 y: O7 [
　　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：4 ~8 A, \# A. Q
) \. V1 q$ J) f0 j
<HTML>) Z+ L( h2 E7 S! x* r
<BODY>
<SCRIPT LANGUAGE="javascript">0 c# V8 c& C  F" E, t

</SCRIPT>- P7 [9 e, C7 N+ k' h+ R# b) `8 {
<SCRIPT LANGUAGE="javascript">; D: s% I. X$ F# H
function d (enc) {document.write(codeIt(key,enc));}7 `6 ]4 e" K# x- `- k' v
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">3 `# }. b$ f$ l% K9 i; R; C5 g. b! r
Decode();
</SCRIPT>
</BODY>
</HTML>4 L9 K& Y& x* _+ S* F! \5 D/ e& I

　　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- P1 L! R

<HTML>
<BODY>* F7 J, x0 |9 s4 o/ |8 v4 B
<SCRIPT LANGUAGE="javascript">3 m* P+ B6 X  x" }8 i8 a8 b

</SCRIPT>) B( h4 o& B6 h8 c

　　哈哈！！:=)是不是很精彩！！
