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！！
* o1 B& r) f$ i0 i  M

方法一：, f! d2 [0 e1 i1 [, ^+ M% n8 w

" J$ x  q' Z" Y
　　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：
) G  K5 d( j! c4 @  K
<HTML>7 U: i! C3 T; b! F2 v0 J+ f. L
<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"2 U& y/ s& S! f: u/ H
var NewWords;$ D) P8 ^6 ^" w  B% n& ]
NewWords = unescape(Words);
document.write(NewWords)' V. T* q& x" L
</SCRIPT>
<BODY>
</BODY>4 g( p7 u7 L# K' @4 f) R* s
</HTML>! J) p2 y, i/ u- ]3 E1 j' d
0 @/ C2 n" u5 j7 w; Q
　　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：6 i  Y' a8 T2 \, r

<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"' H' S# M9 u8 y6 f/ w: P8 A' n
var NewWords;
NewWords = unescape(Words);$ E) N& E% [9 n( U; d
NewWords=NewWords.toString();3 ^" J* G3 o9 M
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>
<BODY>. n" h- F: p& ?' w7 O; c
<form name=pw>9 _8 l4 w9 N  i) g1 ~
<input type=button onclick="password()" value="解密"># ]7 D" X+ T7 j9 Z8 g' }7 O, H5 X8 o
<br>7 T+ K% _  m" `) R7 A
<textarea name="txtpw" cols="100" rows="100"></textarea>  j5 {) j; b# j4 }( ~- k# F
</form>) ^6 u! }7 z( n- V- d. Q0 U1 n6 b
</BODY>
</HTML>/ [: g1 C7 w( q4 V

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：* h4 L5 Y2 R) s4 O) u+ V/ f+ l

<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 ); }; J( E+ q2 I0 D
var sJsCmds ="" +% B% _& w" F( e9 z) k
"?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 P  K9 U1 K% A- O
"";2 w& `) u& [0 F; d! |3 ?' V
var s= Carbosoft( sJsCmds);9 L8 k' f. A& Z9 k" F* O/ _, T3 K
document.write (s);6 S9 R1 S! v- i
</script># k& `: A# I' c# |( x
</head><body></body></html>+ ?/ s& z/ D' D: @! Y: t5 l

　　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>$ P& J! h8 Z" D! ]2 Z5 s
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 ="" +
"?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：
. a( n1 G0 Q8 @4 i
　　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：) u, `: q0 a" ?' n
% N' |) s) a$ Z
<HTML>
<BODY>, u3 ~" C  s# @. N6 U4 G
<SCRIPT LANGUAGE="javascript">" o2 `9 @* m/ S7 n, P
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT># q1 X  O( G  S. N* ^  h, u, u
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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>; D) M' f1 n# b# T
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>" a$ E4 e8 J6 Y8 i& Y9 k+ H' Q
</BODY>/ L; {) A  V, d
</HTML>

　　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：
7 M0 h5 f+ U; X  h6 _1 ~: M2 f
<HTML>+ H  B# H( \+ o; b
<BODY>
<SCRIPT LANGUAGE="javascript">7 o. C4 i, o7 z& z6 `" {
function Decode() {/ U9 L1 {  ]& q, x+ j( G$ O& B, q
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}1 k1 T- X' X* w* x) c( L
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}7 [+ @. k$ x' n* T4 X+ x
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}6 l$ o) V9 G2 c$ J, Y2 a!

　　哈哈！！:=)是不是很精彩！！
