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！！

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：
: K- B  k, [/ Q7 I3 N
<HTML>0 u  b( f9 c& N7 R1 r5 {
<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"" a6 ^: k* X! r# [) J* f
var NewWords;1 ?1 ?  M! A# w- d; }3 o7 ?
NewWords = unescape(Words);
document.write(NewWords)( M" w/ G# O+ y6 w* w
</SCRIPT>, T3 C( t9 d' s( x$ Z
<BODY>
</BODY>: ~5 h4 N1 F+ l# H- T
</HTML>& S4 {6 C5 v7 ~7 [% u# L. H! D$ P

　　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：+ g& j0 @2 s" h+ v1 p

<HTML><SCRIPT LANGUAGE="javascript">6 H  s( _. u7 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"3 Z8 M* G. c2 [0 i
var NewWords;
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){7 A  J9 r: j% E, G/ n5 \
document.pw.txtpw.value=NewWords;
}
</SCRIPT>& |: S' \. h' h6 X0 K
<BODY>  N/ {4 _5 P& ~# H( l
<form name=pw>
<input type=button onclick="password()" value="解密">( _! e% G2 c7 ?8 g$ H
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>( C$ y7 {& e/ M8 ^& e5 \
</form>7 ^2 x8 X# C6 a/ F, c+ |
</BODY>
</HTML>
8 @% J) S  W/ S5 I' J/ }
方法二：: _1 Q: Q. K7 Q* q
: s3 ^! i; C+ N9 g
　　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：  ]! \/ s0 ^/ u& u3 G+ N3 N" f

<html><head><script>' k% \" F. C/ ~0 z$ S9 m. ?
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 ); }) D, s" g7 ^& I: i$ p
var sJsCmds ="" +4 K$ K( R7 K1 \, S7 U
"?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);5 a1 `" O  i# V) x/ n
document.write (s);
</script>1 ~. _" X; y" e7 E* T
</head><body></body></html>

　　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：
( V3 G" `9 F2 V
<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 ); }  a9 p; G8 C8 O7 {0 w8 |( h
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" +0 _  L; c5 N.

  `: @4 H. z9 b) ^+ o. k
方法三：4 H7 U# f0 W/ L1 e( C& E) p0 L' M. {3 ]  d

　　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：( C% O% d4 J8 S/ q& A! d8 P
4 g' K( N0 _; V8 r3 X9 t+ l5 F$ T
<HTML>/ X4 q: W# N. q( x

</SCRIPT>
<SCRIPT LANGUAGE="javascript">

</BODY>. U; b0 J* z6 ~& q& v
</HTML>2 y2 ]4 l% t1 H! M+ I
: d: x; y6 C7 X3 D
　　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>: @* r, B- d8 j# ~; @& W
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}# W% X( V# [+ c+ b; M
</SCRIPT>1 W4 ?, }5 [6 |$ L: \7 S
<SCRIPT LANGUAGE="javascript">

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># r3 g7 |. p7 `, d3 w" [! m% W3 x

　　哈哈！！:=)是不是很精彩！！
