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：

; W8 |) v1 W; N( d4 G+ E  @
　　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：

<HTML>. ^9 }8 b$ v+ \. S
<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;5 z2 N" w! J, F
NewWords = unescape(Words);4 d& c* O# Y  l+ K7 G" _
document.write(NewWords)
</SCRIPT>
<BODY>/ x9 F- j6 A1 u
</BODY>( x, j; b' X, `
</HTML>
9 C% \: j  Q# ~: e0 w' O
　　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：; X6 S3 V- ?! F1 ^
, ~8 }) |; x& p2 u
<HTML><SCRIPT LANGUAGE="javascript">8 i, p5 C7 x" 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"
var NewWords;
NewWords = unescape(Words);, ?* Z3 U7 N. ^" s0 r  a
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;  [5 u4 l/ v4 g4 S: e; L- ^
}
</SCRIPT>
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>* b* S6 U4 }: M- j) P, C! M
</BODY>  t3 n4 Q1 {5 {. Z* H
</HTML>
) d, g: P* M5 a: x
方法二：( U4 [1 ]# F  P8 Q  o' }8 y3 o

　　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 ="" +) e/ C7 Z  z+ ~' e7 a# `1 I/ ?' z7 D
"?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" ++ m, `. Z7 l5 N, V; l- A9 \- C( A  N
"";) m( m6 W+ o" r8 g+ ]& G
var s= Carbosoft( sJsCmds);6 c( A5 v0 T0 H6 y) T2 g
document.write (s);) c9 K/ R+ h& o
</script>& H, o  a) d2 ]6 D# A
</head><body></body></html>
, [+ I- K2 Y9 _: 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：
5 I& Y! p  t2 R. J4 b
<script>& |9 U3 S- U$ |& p
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" +1 S" R3 p; t' ~
"";, f6 G* i7 x  B$ o
var s= Carbosoft( sJsCmds);' }$ f, Z! w& ^
</script>
<form name=qq>- w/ {- P- L/ V6 m) a) l
<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">
</form>/ y7 S0 Q! a# b, u2 _5 \5 M

% I# _$ o. Z+ J& r
方法三：2 P+ P  h# p1 \$ o1 c

　　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：
; I8 g' r% d: g# v; U
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">  L) h( q3 J" {% I5 E$ J: W
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>+ a# w/ U1 R# m' M8 W% v! Z# z
<SCRIPT LANGUAGE="javascript">  N& {. Q3 n0 a
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}" A$ R! V6 @  j1 ?3 C; e2 J5 ]
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();* k: K7 i. u, w9 k2 |: W
</SCRIPT>
</BODY>, T  i& O' F( c
</HTML>

　　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>3 |0 a3 x' j- h; t
<BODY>
<SCRIPT LANGUAGE="javascript">% Y! l6 `. T. ~& w, z) J
function Decode() {) ?3 p5 l- m8 V0 ^& _
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}# |* x" c) e* x6 ?, h2 j  ~7 Z
</SCRIPT>
<SCRIPT LANGUAGE="javascript">8 m" o' t; _+ c2 r! N4 a/ G& x
function d (enc) {alert(codeIt(key,enc));}  F) ^$ f; Z7 E! G. i/ d
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}4 u! N: @$ X9 ^8 ?- O# R& V) ]
</SCRIPT>
<SCRIPT LANGUAGE="javascript">

</SCRIPT>- \! J$ O' T0 D+ }# x2 H
</BODY>/ d$ ?4 a+ _; d1 v
</HTML>9 h4 W) n& d1 ?' i. h: X, @

　　哈哈！！:=)是不是很精彩！！
