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！！

' r( p! t8 ]9 G) H" t8 B
方法一：

% Y3 Y9 T$ o/ b. }2 ^
　　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：0 q- |" m3 B. k' T: T1 `

<HTML>
<SCRIPT LANGUAGE="javascript">; t. p( E( |/ x$ {3 Z% @
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;  l! ^: V1 Y6 N6 A  Q1 Z8 w
NewWords = unescape(Words);2 ^$ z$ U, u1 P( Q3 g: f
document.write(NewWords)# Q: X# {: W- D( P2 r
</SCRIPT>
<BODY># b; I* G3 z# d( z; N* k: X
</BODY>
</HTML>! M/ p: k( f; m, Q+ O$ O# }" o/ M

　　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：1 B3 E9 u' n- K0 x" R# X' k5 d

<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) {. a/ s8 l; o4 |% k& u  f. U
var NewWords;7 u# E$ @* j1 Y7 |
NewWords = unescape(Words);: U  ]% @8 `: k1 ~: Z+ }
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>7 d) I( N8 J! o, ]7 B% |. ^
<BODY>. ^7 Z8 p/ k( N# k
<form name=pw>
<input type=button onclick="password()" value="解密">" r" d  F& m* h; H7 ~: A! A
<br>, O9 e- U3 B! a) ]
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>4 e4 g2 {4 P. t& \7 Q
</BODY>
</HTML>

方法二：

　　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 ); }" w6 b+ ^4 U1 c7 w7 U- C& `
var sJsCmds ="" ++ [. S: S3 C9 X
"?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" +2 l7 A# K0 Y2 q4 Z- ~
"";
var s= Carbosoft( sJsCmds);- `# \8 O0 `; @$ w! u- |) g* ?
document.write (s);
</script>
</head><body></body></html>
- n, S& D7 E5 v1 F$ Q: B8 o
　　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：+ c" ~  f+ f( x& m

<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 ); }- m: [/ L  e% N' q1 x" U
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" +9 `" g" N% W3 T& n0 r+ z4 @

方法三：

　　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：8 ?9 f3 g. v9 ~2 B0 o% \0 e

<HTML>& @% ?: O+ u' a- S0 _' c& r
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>% J8 y, f( O% k& B
<SCRIPT LANGUAGE="javascript"># N6 }, f+ J4 O. g- }5 i
function d (enc) {document.write(codeIt(key,enc));}* i: g/ B, D; q) q5 v
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}) m6 O- c! |$ `% W  _2 Z: J5 n& z1 O
</SCRIPT>
<SCRIPT LANGUAGE="javascript">4 o7 X" S5 x7 ?: e
Decode();
</SCRIPT>
</BODY>3 Y' ^7 V) m7 e. D* V' l
</HTML>
8 X. F# N" b8 O) _' z! c
　　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：
9 K4 i, b! I/ Z: s3 [
<HTML>
<BODY>' p* h# h) ?3 F1 X9 j: X
<SCRIPT LANGUAGE="javascript">* o7 L- L: c# \+ A0 p( h
function Decode() {; ^2 e. b. ~& v  f3 e
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>( k& ^# Q3 |7 G8 |* U
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}; ]# t) Q7 [- N# o$ l5 E
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>' U7 `# q: u! ~/ b7 S* m4 f

　　哈哈！！:=)是不是很精彩！！
