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！！& j/ Y+ ]5 W9 I( V  K8 K+ J) m7 n

方法一：5 J$ F* s( p, D9 T; 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：( T8 d# a! x5 |) t( C# Z

<HTML>( y: U8 Y: p6 C- @! }" m  f
<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);. O; R" x& S2 e5 z' S# r8 j: x  n
document.write(NewWords)
</SCRIPT>
<BODY>
</BODY>6 F. X* W5 z% p0 S
</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：2 w. X+ m1 l3 [$ k

<HTML><SCRIPT LANGUAGE="javascript">2 A3 E2 x% r! i  k# O
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"0 K8 G  B1 M7 ]' S  q% o; t
var NewWords;8 L  l; Q" b9 {6 x0 c
NewWords = unescape(Words);* b+ {$ C! R; o) n
NewWords=NewWords.toString();$ T0 X6 r; X1 ~9 p9 Y* ]
function password(){# R' {% R7 L2 @) `3 r& J+ }* q
document.pw.txtpw.value=NewWords;/ l) j, k2 R1 S8 V0 [
}4 n. W; Q7 t% z8 m& B& v
</SCRIPT>
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">% E5 e9 v+ h% o. |9 A* W; ~! b
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>" p- }5 E+ |; w! D! }9 A7 {2 r
</form>7 V1 ?- n1 M9 A: }; j/ y* z/ m
</BODY>
</HTML>
3 B. M, s, F6 V9 \5 U4 |
方法二：6 M; B+ l  L8 o! |" w; y
! u2 B2 _% F5 M1 ^! F( m+ [* ?. m
　　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>' R8 z9 N" D; f2 X6 H) W4 G
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 ); }! ^% T% G6 x' _3 p2 R( R, N
var sJsCmds ="" +6 v4 I0 {# `3 v) O
"?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" +
"";* q2 X6 Q: Q# [( |8 D4 U
var s= Carbosoft( sJsCmds);( ^7 |$ z1 L' e
document.write (s);2 `8 Z( d- m3 ~( w7 f. i- {
</script>
</head><body></body></html>; s) S4 I3 A4 b4 o- c* \! g6 T

　　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：
! N* [6 W/ s, p: s
<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);

　　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>& r2 Q( o/ V8 F; a1 ~0 x* v3 m/ U
<BODY>) J% U" t. w! G6 i* L
<SCRIPT LANGUAGE="javascript">- ?# }6 b+ u5 m

</SCRIPT>
<SCRIPT LANGUAGE="javascript">- L' ?, p/ e- E) d  m
function d (enc) {document.write(codeIt(key,enc));}& v: D3 t, ?  I
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}" ~# J4 h) n5 ?
</SCRIPT>) n& P; C+ e" |. [' J2 {
<SCRIPT LANGUAGE="javascript">& U* d$ I  I2 `# e% T/ i- a
Decode();
</SCRIPT>
</BODY>$ W# z" x/ C' I
</HTML>- X% P  o: D4 i* [" N: 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：+ Y- O" L8 a) q

<HTML>9 ^; S( @) ?. I7 r# ?
<BODY>3 X, \' D4 T9 H6 h, Y2 T' l
<SCRIPT LANGUAGE="javascript">2 ^. C9 L' F) t& G

</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}% w' _5 a' h1 b7 t
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>* e! b, }0 O  x
<SCRIPT LANGUAGE="javascript">  x% y6 [, k9 |* [9 c6 E

　　哈哈！！:=)是不是很精彩！！
