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！！9 ~! C) ~7 [. |+ r& h& p- z& W8 f

, o" @- }$ M  Y+ ?  Y
方法一：: ~! \$ A+ }) T8 _
# A* h! X/ m0 t' h& h. ^4 E9 S: d

　　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：
) k9 [6 r+ ^4 P1 a) C+ |5 o$ H
<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;8 P) T! ]) Z! R) _, p
NewWords = unescape(Words);& [* ]1 e! @/ ^$ f( o% s- }
document.write(NewWords)
</SCRIPT>
<BODY>
</BODY>
</HTML>

　　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：
9 o8 M4 w& Z! ~) D1 S; N
<HTML><SCRIPT LANGUAGE="javascript">) [& x5 m/ j0 G; [7 J
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;0 S6 t: c- H' J  \
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){* v3 p8 s, q( o( ~+ Q
document.pw.txtpw.value=NewWords;
}5 e8 p5 {7 r2 u7 u
</SCRIPT>3 v9 g) t8 a" B
<BODY>5 w" O- J. j: U, r* E
<form name=pw>
<input type=button onclick="password()" value="解密">0 k' m7 Z' x! n* ^4 E8 R9 @2 @! [
<br>, U4 f8 M3 I3 x1 I# e
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>+ v4 \3 P  Z; }' [
</HTML>$ Y5 Q# R3 k. L8 a- b! _4 u' }
# B# o  t# e  k1 ]$ ?
方法二：
* |3 ~4 k- B6 E' U
　　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：
* S2 B% q. T3 s8 H
<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 ="" +' b1 K6 v( B$ h& j+ i" P2 a
"?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 B, U3 U* b.

"";! k. Y& ?. b: a& f: y6 d
var s= Carbosoft( sJsCmds);0 Z3 f. q3 l2 C( d7 ?1 E, A' Z' z
document.write (s);
</script>
</head><body></body></html>' Q) P5 {. [4 D" }2 W

　　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：' x5 o5 X" w$ n. p

<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. O8 U4 U% h" L' D
var sJsCmds ="" +

方法三：
" P2 ?! \8 P* m" f  R
　　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：/ B  B& c# c, n. ?/ J" V1 O5 e$ _2 ?
: @# Z# b2 N3 ?% k& G' ?
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript"># d5 D- y( v* q2 z
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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>
<SCRIPT LANGUAGE="javascript">
Decode();& L0 B5 Z2 y* l4 `& r7 ^, y
</SCRIPT>
</BODY>
</HTML>
8 b- E) A. C( {" G* _* m1 o
　　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：
, g: t8 V0 z6 F/ ^# f9 u
<HTML>
<BODY>$ W4 c" l9 F. s, x
<SCRIPT LANGUAGE="javascript">- a( a7 t- D6 h7 W$ `, \
