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！！
& S0 M1 f8 J8 a$ q- T, j

方法一：% A# D! b4 h. T
. \  M& w* z3 Q3 g% ~# Q5 m

　　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：6 E7 H( o9 o' d( c+ _  v

<HTML>9 S  k9 U- C% _. B, w. \
<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"  W0 \+ t( r+ K* l% N2 A0 O
var NewWords;3 Y" x; t, k# }6 P, X9 ~$ s, _! A
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT># C# j. l& r8 {* ?# v
<BODY>' C4 b, y; |* f
</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：

<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;) q' g3 r# {& k6 N4 v+ E7 g
NewWords = unescape(Words);3 v, D  A' p& N' Z2 p1 b
NewWords=NewWords.toString();5 A8 g' ]1 R' ^! ^1 s
function password(){) A' X" K1 r4 F: {6 }
document.pw.txtpw.value=NewWords;
}2 Q2 r% B5 r( x' w: ~7 C% H
</SCRIPT>1 V+ T4 D5 a8 r( H2 U" {
<BODY>$ d- V4 x" s" Q8 T" U7 Y) o. g
<form name=pw>+ N8 D2 y2 D- n4 F
<input type=button onclick="password()" value="解密">& k- @6 L4 C. f8 }8 x4 N4 B) N- Q! u
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>$ `8 I5 R" M+ Z# g/ j
</BODY>
</HTML>
) ]9 g- d. M2 R. V, R# D
方法二：0 p' P9 G" n# ^; Q% l% @* q+ b. G& D
5 x, y/ c+ d8 P5 p
　　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：. l, t$ H. S5 j
1 W; e) G9 u2 `& I; S
<html><head><script>( o9 ]# ?7 a) g/ {6 S5 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 ); }. \" R! }! f. t+ D% L4 B
var sJsCmds ="" +: O, F& I. O" i+ i# j
"?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" +

var s= Carbosoft( sJsCmds);
document.write (s);
</script>* @, I! i1 j5 \; z
</head><body></body></html>+ `( F2 v  S* 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：- i) z- d  h9 ^5 X4 P) 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 ); }. B7 }6 l8 O/ W) n  l" ]
var sJsCmds ="" +7 D4 X8 }* d2 A

var s= Carbosoft( sJsCmds);1 F5 w& l# N/ P

方法三：
2 T( j5 ?+ E) l
　　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：! S+ c- g8 W4 u# i! @
' h' z' Z9 P3 @: f' G0 |# _
<HTML>6 a$ ~; {7 }& o6 H9 e% ?$ u
<BODY>0 t& I8 z1 X0 L8 b/ h* l1 \+ d
<SCRIPT LANGUAGE="javascript">

d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}: Y4 \* k! U4 h" j3 W7 ~! @
</SCRIPT>8 l7 D4 s, m1 c/ a
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}) Q0 j8 C) j4 g4 v3 p, y! k
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}5 I5 U* {8 S( o6 ^. y; f
</SCRIPT>9 q/ B  \* L9 }1 U, s$ i' I, `7 g; r
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>. w4 t9 s2 t+ u
</BODY>. D7 ?" i' e' q8 l' i/ `0 c
</HTML>+ n/ B3 |/ A. D8 w# j" ~5 ?

　　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：

<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>: [% t! M4 C1 g+ ]; Z
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}* _) y  d, j) ?1 Q
</SCRIPT>7 A: t4 u$ T- Q1 X# Q! z9 |- y
<SCRIPT LANGUAGE="javascript">/ k& |5 J4 u# R. Z& _3 e/ Q. g
Decode();; {8 v- y! b; l% E
</SCRIPT>) g; l9 N& |  j9 U- E
</BODY>2 X1 [4 s6 k6 p2 i- n# ]% q" p  ?8 r/ D

　　哈哈！！:=)是不是很精彩！！
