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！！
' v8 M" x* t& `' V0 `0 {5 o
( q# {7 \" I$ _/ b0 n. ]. k
方法一：& e3 w3 q, W3 T' f5 Q. J9 ]
/ P5 e% G- q- B: H" a. F3 C

　　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：. F* P0 N4 [5 m: L* ?0 J

<HTML>
<SCRIPT LANGUAGE="javascript">+ \: ]7 V9 g( q9 E: |
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"9 d4 j) s3 ^- a, g
var NewWords;& A8 b, S2 {8 s, _3 W  Y4 p
NewWords = unescape(Words);
document.write(NewWords)0 t3 n8 V0 E3 s2 U0 F7 }+ ^
</SCRIPT>8 a; b5 E+ x" |; T9 \) ~
<BODY>& d! I2 G- H; Q0 |/ Q
</BODY>/ {- s# Y" y5 d" z9 l3 N
</HTML>

　　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：
/ c1 k$ n7 u/ t. X
<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"# z5 C* y( h( R1 O+ k. m/ o
var NewWords;
NewWords = unescape(Words);( u  h6 _; ~4 Y- f
NewWords=NewWords.toString();
function password(){8 _& u, R1 a" }; B
document.pw.txtpw.value=NewWords;
}
</SCRIPT>( b0 R9 ^  _- T6 p# j, C1 J  I! R
<BODY>
<form name=pw>% Q/ P' T( Y1 c+ C
<input type=button onclick="password()" value="解密">' e: N6 g$ p- P9 d9 p( d- M5 Z
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>- N0 u- N! w0 d: D# c/ q: Z
</form>
</BODY>
</HTML>
* {8 @2 c& k9 p, m
方法二：$ @+ s8 k8 x" B' K' p! R

　　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 ); }: X! m: j$ l, ~# J8 n  s  o. B4 X
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);, f+ ]+ |0 x; L  Y4 L0 O  m* x( O
document.write (s);/ G8 B( @& v& p$ \; ~% X/ z4 x
</script>- ~) D1 W/ `0 l& D; L% E3 X& [7 y+ f" ~
</head><body></body></html>+ a, I" \* X' }' x0 D3 T
( n: L" [8 Y0 B* E! e6 J
　　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：6 K* T. X: f. s- D. Z6 Y9 w
/ @; S. f$ h, K9 `
<script>. z% g. v  B2 B" t; ~4 q6 j' f
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" +8 S  D/ G: N" S2 _0 ^" S$ E.

<input onclick='ww.value=s' type=button value="解密">; ]) l3 M$ W# h/ u
</form>

方法三：2 U9 j/ o4 Q1 g$ B1 V* k

　　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：+ o. j) }3 x2 S0 f

<HTML>: J9 E+ F+ r6 ~' |8 Y' ^( o+ ^
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}  n8 ]% ^6 y* ^7 y: x
</SCRIPT>
<SCRIPT LANGUAGE="javascript">/ Y$ R! R- C9 [
Decode();
</SCRIPT>7 z/ \  l' p# t4 \4 e
</BODY>
</HTML>8 Y$ t: n6 F( z% e; ?; [- k+ A1 n

　　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：
  f* f7 C& R6 ^+ v0 F9 x& g& k
<HTML>; J' b  N5 h; ^
<BODY>$ g2 P% Q# T7 O5 E0 ^. Q- F% e& y
<SCRIPT LANGUAGE="javascript">* Q7 R" c8 v6 @; z4 m

</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}& p! |. j5 p- |+ E& U
</SCRIPT>
<SCRIPT LANGUAGE="javascript">  v; N3 O, r: R! x$ o
