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！！

' c: E* {0 F2 V' @9 m- w
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：, N2 y0 O6 _/ j$ `. i, P7 w  `/ G6 S
, b) x$ \0 l  Z) [/ Z  j0 m
<HTML>9 g8 ]$ j% {/ J8 ]
<SCRIPT LANGUAGE="javascript">: q; C* A4 m" D+ d: v* j
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", b+ C& @/ V; F. V$ n  C& C9 f$ u
var NewWords;) X# I. n; \5 z6 h, N
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>" m  O2 k2 y; a! B6 }7 U
<BODY>5 P+ L6 K+ e! A- y! K
</BODY>" F" |( l4 ^* z( H8 f* O) m/ w
</HTML>
4 ^; q) y* O& q$ f- \8 {
　　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 f" }. S0 t4 X8 c' i4 \# W, N+ `

<HTML><SCRIPT LANGUAGE="javascript">; n8 f9 j' K' y6 }5 `
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"" h! Q3 j7 @( i7 O& P" ]; d6 H# L; l
var NewWords;
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>
<BODY>" M, H) J8 D$ g7 t$ }
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>! o% b% G5 y" `6 m2 Y) |  q  y
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>2 C1 j' g6 P- G9 X# m$ P. e
</BODY>
</HTML>

方法二：/ I2 g3 A1 `' J% H3 o4 Y# W3 Z& 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：

<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" +
"";
var s= Carbosoft( sJsCmds);3 x- S9 `+ ?/ G
document.write (s);9 a4 C" E# w0 D3 H- B: j
</script>
</head><body></body></html>& u3 t$ i; ?9 F3 A) d# z5 h1 b

　　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：# ^8 c5 z+ O- h# [$ a: t* 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 ); }5 G7 t6 F3 j) f2 P. y* w: B
var sJsCmds ="" +. m/ P* L: G4 ?* w$ p) t
"?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" +" d8 v% l/ z7 N& C

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：: f; z0 c* Q- k$ z" U& C
/ @6 b+ x, C) A0 [8 I& T
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">  U% t  O, T/ B+ x" v, y
function Decode() {7 X5 _9 _9 u4 r* X7 O
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}3 ], F! q# c3 t& c% n, f
</SCRIPT>% x2 h) {: O8 n' x0 t
<SCRIPT LANGUAGE="javascript">8 m$ a* w3 H- y) v( k
function d (enc) {document.write(codeIt(key,enc));}4 L" r8 T& ?& u
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();, ?6 N) G8 S& T4 _% B5 v# o
</SCRIPT>
</BODY>
</HTML>
) _/ y5 e) [: l+ E0 r* y
　　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：1 H, i4 z9 @* _5 B0 G8 \1 {7 B. Z
+ M8 O, ?+ o+ M1 z& P8 v
<HTML>4 W* N- ]5 c0 c  u* H1 q* Q
<BODY>
<SCRIPT LANGUAGE="javascript">

</SCRIPT>; s; v! n3 ^, C9 P) U
<SCRIPT LANGUAGE="javascript">$ Q. D+ H: R4 v" Q+ r( @
function d (enc) {alert(codeIt(key,enc));}% ~! o$ f1 ?1 @9 Y
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">4 k6 ~& [; ^& f5 w

</SCRIPT>5 L8 i! T$ l3 t4 u4 K, `' R
</BODY>6 A; v) m: Y& J' Y& [
</HTML>

　　哈哈！！:=)是不是很精彩！！
