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：( `; t6 k) @4 }2 b* k

& H, ^9 \( B# W
　　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：6 g1 |+ }" e$ Z

<HTML>
<SCRIPT LANGUAGE="javascript">5 v; o. N) y4 r! m' 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"
var NewWords;8 X6 ~5 o/ R6 X5 P4 r3 {
NewWords = unescape(Words);9 `- z+ W, L7 S6 K, U9 b) w
document.write(NewWords)+ N/ ?5 @& V- H  }- O4 x& [" z
</SCRIPT>; S$ K7 b* |% G. h7 n- d
<BODY>! G/ {( J; G7 q
</BODY>
</HTML>
! |* k- `  j% \8 d' L2 e
　　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：% u4 C9 K6 ^* H! l) s4 I
% q, g6 F, y/ O6 l7 `
<HTML><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;* Y% R! b9 W  H5 L! b1 l9 a
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){3 M/ S/ {; i/ c- c5 G) A0 G! s
document.pw.txtpw.value=NewWords;. \) A$ y6 A" c2 g  A# J1 _! k' N6 c
}
</SCRIPT>
<BODY>, i* ]3 i% _1 q2 G1 {, U
<form name=pw>0 E% q) i4 c. K8 h: T
<input type=button onclick="password()" value="解密">
<br>! Z( |0 a3 e, s
<textarea name="txtpw" cols="100" rows="100"></textarea>! ~" q) g5 c7 ?- f9 ]7 o: a' W1 g3 d0 m
</form>
</BODY>, j1 C0 Q) _' q0 F5 ]
</HTML>
* J, L0 [5 S$ r* y1 x+ H
方法二：
& l- ]3 @  V3 A
　　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：* ?" ]& U( [& Z  |, p
( D+ L1 q& D* ~! W. K1 R3 f4 W
<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 ="" +; A9 L4 h1 u" f: p( b! q
"?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);
</script>7 `, n( _/ U4 }1 i1 n7 n
</head><body></body></html>
6 J& E3 s9 U' N
　　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：! u$ W, E# I  M# N$ w$ q

<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 ="" +5 N1 V; Z; O0 [4 q7 Y; m6 [! t0 H6 B
"?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);! l! n% w* N6 H/ ^1 @! n

</form>

/ G! m  @( w0 _8 |9 i4 F
方法三：

　　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>" {' M' m) S% {  K# x
<BODY>
<SCRIPT LANGUAGE="javascript">& T, T, X; [  |# B
function Decode() {- G) E8 }2 F& r) G
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>: B# |" W5 z' j5 z- `
<SCRIPT LANGUAGE="javascript">: I' |' D& R4 E' `
function d (enc) {document.write(codeIt(key,enc));}8 N% l7 o1 G0 \. s! V" ]# e
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}# a3 Z3 c: Q6 h3 r# t. E; C
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();8 S: e6 C6 _* U1 W- Q
</SCRIPT>
</BODY>: L5 g# m0 R2 Y0 R' {  x3 [' b8 ?
</HTML>! P- K0 p; ?" e& ^7 ^

　　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：/ h+ K) P- }! y+ r* N

<HTML>
<BODY>% ?% l2 q; F6 r3 m) K
<SCRIPT LANGUAGE="javascript">5 C% _6 z4 b; y" y% d. U
function Decode() {% F" S) P% R6 U9 E: {: U: l9 F
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>4 h0 j! s' F- p: Z
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}% B& l5 t( k' x6 p! g
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>; a1 {5 H8 x- C
</BODY>
</HTML>. P$ p$ `/ Z- J9 K

　　哈哈！！:=)是不是很精彩！！
