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！！

# U: ]+ V4 s0 Q. c3 y
方法一：8 h0 n( `# @1 m3 S  K. \+ \, O9 Q

. l$ F1 K; ~. I
　　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：: [" K2 m# k0 ]  W

<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;
NewWords = unescape(Words);6 |/ L) W* o5 S3 i0 d  [) X
document.write(NewWords)
</SCRIPT>' V0 }2 O* _% j1 c# P9 f1 z
<BODY>
</BODY>
</HTML>4 M$ ?4 G. _! j9 h9 p0 k

　　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：, I" }) q; ?9 u8 d
7 p- y8 ^0 R7 t! u) v, g
<HTML><SCRIPT LANGUAGE="javascript">, {1 }( K' e( V: h- y, k  T' Y- b- u
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();
function password(){
document.pw.txtpw.value=NewWords;) k& B' Y' G/ p  z: V
}
</SCRIPT>
<BODY>" s' V% G3 t6 m' ]5 L( N
<form name=pw>
<input type=button onclick="password()" value="解密">, e3 I0 G, Q2 Q
<br>( Z% _5 f+ g' _0 @0 b
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>) |7 V% ^" q% v0 F$ z5 ?
</BODY>$ L, O1 [5 o- ^4 [7 Z1 I: F
</HTML>
" v; {7 }8 S7 C( j+ T# U
方法二：
4 _3 S/ {: m% K% h
　　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>  F% E1 ~5 L. l+ R& x9 F  k# |
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 ="" +4 C( k: X" Y$ K: c1 e* T* y0 G, ?, M
"?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);; R7 W8 F- q* W* N" T0 [6 ~
</script>
</head><body></body></html>  ~' |7 n4 B( O1 E
7 G/ l7 F$ A7 ^6 d
　　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：4 @. L0 f4 `2 e

<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 ); }4 [& V& j$ k# l8 P. [
var sJsCmds ="" +2 x/ Q8 ]- g0 X5 V

方法三：
1 }# R% n+ G4 T$ f
　　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：8 q$ ]& K- c) @
8 D* W  Y4 v/ [3 n4 k% B# z
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {9 l1 m/ P, _& u3 b% R! s
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}# D& v. a& S) l/ O0 X. x
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}1 n5 u$ k$ j: n  g
</SCRIPT>
<SCRIPT LANGUAGE="javascript">' ]& y0 I# ~6 j. z- f% U" G
Decode();
</SCRIPT>
</BODY>/ [9 J% x3 |* T- X; X& o3 b! c4 J
</HTML>2 [5 W' W4 Z- x9 n/ V

　　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：

<HTML>: D+ r0 m: D) A7 H: ?0 M) X
<BODY>; }" F' O2 L. _  T9 W, ]
<SCRIPT LANGUAGE="javascript">+ d4 h6 G4 J3 P8 I
function Decode() {1 j( T9 c6 f4 E% S& A
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}9 ^1 ^* y5 B3 l/ \9 W
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}. s$ R! O' U$ s* I8 ]: Y
</SCRIPT>
<SCRIPT LANGUAGE="javascript">2 S6 D+ A- D# @0 a& n( f) H; o

　　哈哈！！:=)是不是很精彩！！
