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！！
/ m$ d; R& Y5 f

方法一：: a% k" k1 n8 t- x, @! l: ^

　　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：
3 e8 b: p  a% m5 M2 w; h
<HTML>" [6 K; i) A" _+ X: s. }5 H) _
<SCRIPT LANGUAGE="javascript">4 V4 }: `+ J& Z+ D1 X1 `/ P
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"* Q+ t4 q5 F: I
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>9 U4 i$ b- r% e
<BODY>
</BODY>% D+ y8 l9 F: U
</HTML>2 H& B+ d" |4 I* n/ v7 |
' V# a1 R; _* B( R# Q% V
　　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：
3 ^0 f7 N3 M( u
<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": V/ o+ A- Q* }! \! c# t; c
var NewWords;! C$ S# x/ R/ I/ f& Y4 c; R" }
NewWords = unescape(Words);
NewWords=NewWords.toString();- C3 {( J9 A* u% u$ ^
function password(){8 U5 H& \: |. ~  x0 R
document.pw.txtpw.value=NewWords;" ?  A' s6 O( I0 x, S0 D! B
}
</SCRIPT>
<BODY>, v6 T4 Z5 n( P4 H  `. ~8 A7 z, X
<form name=pw># J0 f  c5 L* ^% O" e, e
<input type=button onclick="password()" value="解密">
<br># X4 e, c1 ?% e$ u# M
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>$ s  Z, F4 P4 V; G. \0 q: L
</HTML>

方法二：
) C& |* ]* [# w2 s; x- s
　　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：3 y2 D; g) }( M0 Y! N& u
, p2 x8 i) b2 Z, t) i* e; p: ^4 K1 R
<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 ); }% @  {9 n/ _" K0 ^* r; p
var sJsCmds ="" +- F2 `! g- V9 c% _7 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" +8 T7 u( A4 o+ y

var s= Carbosoft( sJsCmds);
document.write (s);
</script>
</head><body></body></html>+ C# V7 }. x+ t3 T/ E( ?
5 |! p2 M4 Z/ {# {+ [
　　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：, W! S7 R$ {' ~: A  r+ g' w) F* t  ~
8 M& F, j! c' l9 X; p( W# x
<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 ="" +( D' I* e5 i8 r' 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" +!

方法三：, p. R6 l* c9 b/ [

　　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>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {. C$ \8 H. L; e% ]8 K
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}) e/ }& v7 Q/ I: y6 g2 O
</SCRIPT>$ a" Q6 g# ~( H1 L& _, G
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}; N# [7 c8 s* B8 Q: k% C( F
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}  g# I/ U: V' f. g2 D
</SCRIPT>
<SCRIPT LANGUAGE="javascript">) Q! v* i+ @6 \* `
Decode();
</SCRIPT>- Y4 D9 Q9 Q+ \/ h
</BODY>
</HTML>% W2 I1 c% x! O. e
( u4 q) O1 Z# |
　　还原的时候，也必须每行单独解密，用下面的方法可以看到源代码：
6 a* _+ k4 L2 `1 x/ x* o$ R
<HTML># a0 C. c( {- n1 B) y' y
<BODY># |4 f3 ]  s3 U; j* [  |
<SCRIPT LANGUAGE="javascript">

</SCRIPT>6 @% R2 l# v* c+ d- a
<SCRIPT LANGUAGE="javascript">5 J" V- ]$ }0 U8 M
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;}4 H0 @1 k# [  p" Z, ~7 T  ?4 @6 v
