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：
9 @/ B' ~( Q$ {; c& U

　　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：% K8 a- U% x  ~
1 {; \% `2 U) S
<HTML>0 a' G# u. w0 ^) ?) A" C' e
<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"7 u/ }2 K# X( X1 @# H* J% t+ f
var NewWords;8 ?+ i5 u! o" V8 [% {
NewWords = unescape(Words);' D) f8 e" {' m
document.write(NewWords)
</SCRIPT>  E: M8 ?( D: g# `* j; Z. S$ X
<BODY>
</BODY>
</HTML>( u% Z3 o. W/ W( R* [9 m) v

　　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;
NewWords = unescape(Words);
NewWords=NewWords.toString();: n# V) A5 T7 d9 C+ y4 K
function password(){& }: w- Z( z# c) Z, q# Z
document.pw.txtpw.value=NewWords;
}0 x5 n- b5 d- E9 l
</SCRIPT>4 }: {( n7 O( T  D+ {* x
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">5 |. z( \" X6 g  K
<br>8 e5 ?- s6 ]- ]
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>. S2 t( o- l( p  ]8 E
</HTML>

方法二：% a7 D4 `- Z/ @4 _4 p2 \

　　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：3 S$ d2 W2 D7 z+ F, |+ C! v
1 \% J  S7 D  z- ]# q  B* d( d8 W8 Z
<html><head><script>; I2 k. R- Y1 e% }: Y
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 F* n$ R5 l0 Z7 E# E
var sJsCmds ="" +( t5 \  L- D6 B4 h
"?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" +
"";( c3 r( N9 O  L! i" j* @
var s= Carbosoft( sJsCmds);
document.write (s);8 y* u6 t4 X# V9 @
</script>! q8 h* |3 b& [; j- a
</head><body></body></html>
4 c4 H7 @( `/ z! S) b7 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：9 W* Q- ^1 _; L5 b. n
: w$ \3 S/ B. u* t& V' w" g* g
<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 ="" +- o! d8 _7 ?4 Y% n; E9 t
"?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" ++ y0 o+ q3 j' x# y% I9 c9 B3 x

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：# [6 Y$ d6 N. ?
4 g% M9 a3 k; O
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}% r: I0 m" u  B3 g
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}# c3 r! Y4 J/ a- M1 b
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();( H, w2 C! k" f0 n; v
</SCRIPT>: b) ^! I; p) c) `+ V% x
</BODY>: `% e8 g1 O( X, ~4 \
</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：, ~! C$ q: F! B' P0 g( w

<HTML>5 y2 G# B4 _" p( m
<BODY>
<SCRIPT LANGUAGE="javascript">0 b' X; C" f3 N# \# i5 H
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}8 ], N3 [. }6 n. e- X' K
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}0 E  U5 T& I) U( O; Y2 {
</SCRIPT>" r0 q* d( h0 n! S
<SCRIPT LANGUAGE="javascript">5 k6 V2 t3 B0 F6 e
Decode();
</SCRIPT>9 o0 B+ k* T2 C1 x, f
</BODY>8 G& n4 V, Y3 Y, \; M. j
</HTML>; p! a+ S: l: ^4 W! M

　　哈哈！！:=)是不是很精彩！！
