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 A0 _6 [3 ~: k  J$ 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：
4 M8 v# K  V3 A$ G8 v
<HTML>/ n+ E  s# H* Q+ C2 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 G7 E4 a0 ^0 u$ ~
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)3 N7 u* D1 J1 a
</SCRIPT>
<BODY>( u% d% x6 u, R9 `, o
</BODY>
</HTML>  A$ S) V3 w9 |) K
' K- A% V* J. \4 `* K+ ?3 S, h! J
　　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：. {/ r( R* s, n2 \* P7 p  r

<HTML><SCRIPT LANGUAGE="javascript">4 @. W6 F# [5 j1 L
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"! Z1 d: b5 y3 P3 w2 \' d: T) d* t
var NewWords;
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){9 J- f! j. j% i
document.pw.txtpw.value=NewWords;! k% a/ E8 Y6 A; a* V% u4 F
}, |/ C8 |. v& ^
</SCRIPT>
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>9 T7 q& l+ }" r$ F2 f6 S
</HTML>

方法二：  R) y! d, `2 M9 S
" g- U" l1 Y6 P$ |( F
　　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：8 A  C3 x1 P$ B0 @7 ~: Z( r) t
8 J. R6 U/ }. L0 Z
<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 ); }6 u- ?8 A, q, |! w* b4 Z% O
var sJsCmds ="" +7 E* F* ]1 k0 n7 w* W$ [7 S
"?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" +
"";* G8 B  Z0 X  ?5 l% g
var s= Carbosoft( sJsCmds);
document.write (s);
</script>" e5 s. p- U. P. D
</head><body></body></html>+ u: N! B. j1 x! c

　　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：; }7 H6 ~5 w% u# X8 E

<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 ); }$ ]9 i7 k8 x' Z6 w! D
var sJsCmds ="" +: W: O, `# I  z7 D# m- 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" +
"";
var s= Carbosoft( sJsCmds);

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：; u+ j' l  Z2 b  U) T4 e
0 Z7 [( o# M# z2 n
<HTML>$ B4 e2 `* _1 l. U7 J
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>/ Q$ o& L2 C! }
<SCRIPT LANGUAGE="javascript">$ i/ Y. W- [0 ]+ I& `2 W7 n2 ]
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();
</SCRIPT>
</BODY>
</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：* T, I5 B; N0 ^0 `5 {
" C( R' E) X4 \1 `0 T7 E
<HTML>+ }/ m" t- @  W: J, n- ~" Y, c

</SCRIPT>. |- F* I4 [! O
<SCRIPT LANGUAGE="javascript">( }0 C" ?3 z: j; j" D
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}
</SCRIPT>. |' l' o3 n7 k. T6 P/ w$ \1 \% p

　　哈哈！！:=)是不是很精彩！！
