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：
6 k! E- Z9 c* B/ I

　　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：: ?' r6 T. B. j2 D
5 c* G/ E2 U& Y/ k9 p/ q
<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"& M9 V# R0 k5 g7 {, K2 h" h
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)/ U" w' Q0 S% @7 P' K9 W
</SCRIPT>% {" \3 \/ {; W) Q5 H/ K* V
<BODY>8 t! I% J  i$ C* c* z5 R
</BODY>+ m; b1 j' O" H' u7 M
</HTML>) d  e) l! j7 Z4 X
2 S6 z6 x$ q( ]4 S$ a% a
　　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：
$ p: j' k1 C# Q" b( f6 i
<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"( j  e; |4 x7 |4 u8 A" C
var NewWords;
NewWords = unescape(Words);; a3 t3 a9 h! `7 x( |
NewWords=NewWords.toString();( |9 O, v' K7 o7 ]1 x& J
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>
<BODY>
<form name=pw>. }4 t" v% B5 B5 g
<input type=button onclick="password()" value="解密">/ t# ^- X+ Z1 G7 U3 ^
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>- L; ^) \% j; z/ m% E; \" \
</form>
</BODY>
</HTML>2 }. F7 |! t5 q+ m3 W6 d+ r) g

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：, I! O$ d  k, Q4 s

<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 ="" +; I$ \/ E4 O7 R3 \! n$ U) f
"?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" +/ i, O2 A4 D9 e- F
"";
var s= Carbosoft( sJsCmds);5 R4 z' H+ S) z* _3 e, |- P
document.write (s);: ^5 r6 U  n0 ]0 l
</script>
</head><body></body></html>" ?% M' V4 e3 X2 \% p
3 W( j$ B7 r3 q/ f
　　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：

<script>  ]- R1 r* G3 Y4 C
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 ); }7 S2 o* n$ ?( s6 r5 `
var sJsCmds ="" +" n, w0 u& h- v
"?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 F5 z& Y3 c3 Q& i  u% d

var s= Carbosoft( sJsCmds);

<input onclick='ww.value=s' type=button value="解密">
</form>4 b" Y; _. z' r$ h1 ?

方法三：
$ L( U& V, F, ?% b
　　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：/ K1 v- s0 z9 l/ j9 t
. w/ {* K1 d' l( \
<HTML>% p, |  t" u$ z+ P
<BODY>) @/ W- g' w) q- Q7 m4 H" w
<SCRIPT LANGUAGE="javascript">
function Decode() {& \' i% k' W) d; E. M" z8 i
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>4 A9 N! [# f3 e. G3 p: l' N
<SCRIPT LANGUAGE="javascript">3 y6 Y: ?. y6 a- a( n3 \3 g
function d (enc) {document.write(codeIt(key,enc));}) f& X$ m: j  a5 Y
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}4 p  M# F# [4 k0 l8 W2 C( k
</SCRIPT>
<SCRIPT LANGUAGE="javascript">* g( j* Y+ X4 Y$ @* s
Decode();3 M) j# a& M0 E. c
</SCRIPT>
</BODY>: q' X8 t6 Z. D* f
</HTML>
7 @1 x- @; b/ Z3 Y# [: ?
　　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：8 N6 A4 i( Q" H4 _- f* |, J* z

<HTML>8 r! @; v- a) N# k( [/ n

</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}5 b' N3 w/ s3 C) W5 H
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>
<SCRIPT LANGUAGE="javascript">

　　哈哈！！:=)是不是很精彩！！
