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！！/ p/ W; L1 ^9 C* i8 O

/ Q) I# s0 A- U8 K! h( u; @; @
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：

<HTML>; X& C9 m+ m$ t% l
<SCRIPT LANGUAGE="javascript">+ k1 ~3 z, X4 D* x& V$ T$ i1 N# f9 ^
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"2 B4 D& x! u& I% ?$ H/ u+ `2 T6 H
var NewWords;0 [9 G% {. Y1 s  s5 B# A/ ~
NewWords = unescape(Words);' x* z# V: S4 O" V* d. m) N( N6 `- u
document.write(NewWords), @0 l$ ]+ w" o; K$ i. r4 c
</SCRIPT>, |# Z! W9 S- q
<BODY>
</BODY>
</HTML>% h: g$ V* n/ K

　　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：$ W" v. |$ g' ~+ q3 f
$ x; @! m8 f9 h, P3 s1 o& f
<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"
var NewWords;5 {7 E1 _, f1 `2 y# G
NewWords = unescape(Words);
NewWords=NewWords.toString();# G& i: k$ X/ ~2 |
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>
<BODY>
<form name=pw>! u4 g; b! K! Z+ c( B" P
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>
</HTML>/ G, L$ A) [" a, v5 i. ~0 V
) L7 U( ?* U3 m$ ^2 w6 |8 d1 i' h
方法二：2 `  A" c- w5 h1 D! l* x; s
3 v" n& X% d/ ]& g  V
　　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：
8 b/ A! g/ N/ _0 Y* E
<html><head><script>+ [" F# A6 X/ O) H4 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 ); }6 {/ n" D! Y0 B- B1 x
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" +& o- ]. y6 D- B7 C+ V, M$ d

var s= Carbosoft( sJsCmds);
document.write (s);
</script>5 u' _& D( x+ q! n5 n7 {" `
</head><body></body></html>
/ H! T$ ]- N# N
　　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：# Y4 }. |$ M; O: u) Y: p0 D6 p

<script>, n0 x# l4 C) o
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 ="" +4 u3 U5 t- K) j1 o5 k; }( P2 |
"?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：( N4 Q! V) m4 \9 s% p' u

　　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>1 o; |1 `7 @+ q
<BODY>5 c" ]1 D* N9 K' W8 [
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}+ E4 R2 k( C' Z% P
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}
</SCRIPT>, ?; `9 {# i' P
<SCRIPT LANGUAGE="javascript">

</SCRIPT>- ^. s& E" V; N  C. [
</BODY>
</HTML>
$ Z6 z3 ?" ?& `, g/ O) p
　　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：
; X! |, Z: s! d! R& N( P
<HTML>- T* n, v( V7 y5 C6 a# y4 r
<BODY>
<SCRIPT LANGUAGE="javascript">

<SCRIPT LANGUAGE="javascript">* c% O# S3 l  @/ r& p

　　哈哈！！:=)是不是很精彩！！
