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！！
; }$ S* k) m8 T, p: u1 n

方法一：- B( K( H/ H: R4 F$ N, ]
& q! y( ?+ W5 ]! d& q) |. O6 D
; o0 m, Z7 @+ q: s; 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：# I& i: L1 J' `7 B# k6 ?
2 b7 p. c4 m! ~2 }0 K* ^! N* @
<HTML>
<SCRIPT LANGUAGE="javascript">* m6 F5 x( V% R9 |0 N5 D
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;' g3 C1 N  d# B' [0 ]3 G2 h
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>7 z0 \, i5 G9 F! r
<BODY>  T+ v" v6 D+ N3 L5 E& G. F% T
</BODY># a( B; U! L8 O& R4 ~! O) w3 ?
</HTML>- U' B9 A, K5 l/ e! _5 _1 a6 g
. x3 y: G& \: x
　　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：
7 w- d; j7 N. J$ G* @
<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;
NewWords = unescape(Words);- n4 u3 F5 K) R
NewWords=NewWords.toString();% g, |& b' X7 }1 }
function password(){
document.pw.txtpw.value=NewWords;
}$ m! B+ o5 C* s1 d
</SCRIPT>9 J3 R. M8 J' P% J" U
<BODY>) ?% U. i% a; z/ {
<form name=pw>0 J( e, y" q+ N$ l. C( Z' T
<input type=button onclick="password()" value="解密">2 t+ z6 h. Z8 N
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>- j, V9 h3 Y" P' t* l9 U
</form>3 P8 \) B- o/ J6 P
</BODY>
</HTML>
& ?! ~& a, {! {+ j
方法二：! a( }& r1 R* B9 A) n, \4 w

　　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：
$ n* N, {- A# R7 L% c
<html><head><script>4 |/ {. @0 e3 Z5 t- M7 F, U
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 ="" +. q. N) x) D+ }' @( N
"?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" +/ d% b3 U) n: ]: y" F  g% \
"";- x6 {6 }# I) N" a9 G" d
var s= Carbosoft( sJsCmds);
document.write (s);0 p- E5 ?2 i9 c" Q
</script>: ~( g7 T; f! l2 P' _
</head><body></body></html>- A' V- ^$ e2 h- k" X

　　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：
- W7 k/ K3 g2 d4 N
<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 ); }/ X3 [% p$ n" t% R$ G, q
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" +
"";/ `8 l7 r& A' k" A) L
var s= Carbosoft( sJsCmds);. B5 M4 U5 X1 D
</script>
<form name=qq># y$ a2 U" ]1 w' v7 n; e# x7 z
<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">
</form>
3 c& _$ p6 [& S% t

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：1 u* G+ @+ Z8 h' }8 U* ^  Q' K

<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">7 Z/ {4 o- ~8 q' N
function Decode() {' W  z/ U/ }4 R1 h- k7 Y3 o( |
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}1 g3 o; Q. \; t2 i3 Q
</SCRIPT>
<SCRIPT LANGUAGE="javascript">- i$ s: J6 M8 v; s& x4 ~
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
</SCRIPT>/ V# ^# D1 `* L# Y% X/ K& ?
<SCRIPT LANGUAGE="javascript">+ U) c9 l2 }1 E2 }  M$ p
Decode();
</SCRIPT>
</BODY>
</HTML>
* y- X/ L$ b, V! t! R+ w
　　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：# J6 Q$ n0 V* `) \5 p9 t  g
. O. P8 e1 c; @; R$ k5 m8 _- E
<HTML>
<BODY>0 Z6 U1 U' H5 E; I$ ~* I
<SCRIPT LANGUAGE="javascript">
function Decode() {9 G2 G, k9 O# W) a" C

</SCRIPT>2 R" e) c  k6 N
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}$ Y0 ?  ?. E9 z: U
</SCRIPT>* r+ m7 J6 P6 l7 {' f! O
<SCRIPT LANGUAGE="javascript">2 C& @+ J$ j' k; t  c! {. h. F* M

　　哈哈！！:=)是不是很精彩！！
