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：: H# V* c; v) G' x+ b/ S
% F+ K, ?5 ~8 H0 T
; }7 Q5 r5 C5 k# p( D# e/ h
　　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：

<HTML>
<SCRIPT LANGUAGE="javascript">+ l' I9 z$ }2 g+ l& b. E) T
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"& w" l# o* F2 Y  F
var NewWords;
NewWords = unescape(Words);7 N, I' ]- }, k+ ?. Q- [
document.write(NewWords)/ U# h7 b7 q( p' x! X
</SCRIPT>, d# H" g" ]- R3 I
<BODY>% L: C8 i. S9 s3 Y. ?" `" e- f$ M
</BODY>- A5 o, y- M  C
</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：' h6 ~3 I! a: \& m
2 @: N; h! l, I+ e/ \1 @% @) G
<HTML><SCRIPT LANGUAGE="javascript">: r0 n9 v) @7 |5 O
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);. L" _, {' a# _6 k
NewWords=NewWords.toString();  `# b( \( X2 J& o* u, R5 B' b
function password(){0 u  ]4 b* L  t
document.pw.txtpw.value=NewWords;
}
</SCRIPT>$ g' G; E) M0 W5 s' h2 }( Z
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>  ~! n( {, o' t1 i( H
</form>& u' o( i. b" u# ^& F0 D+ K4 A* C
</BODY>: E% X+ z/ g0 C0 ?' `
</HTML>
# S) b+ w# j% R! U' k
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：
+ l- T8 [7 R- S! s9 i- ~/ a9 I, ?" Z
<html><head><script>' B5 n) E# x5 E3 P
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 ); }( @' [0 R5 B, |5 @# m
var sJsCmds ="" +# A3 j4 P* X( r- O! ]
"?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" +7 U1 [- R/ q1 Y4 \. V
"";, `, j9 u: z; K+ g$ }
var s= Carbosoft( sJsCmds);. x/ N+ j0 H- d2 [
document.write (s);6 b* Y! E- u2 |2 B
</script>/ A7 S! ]/ j, P
</head><body></body></html>2 }9 \  }) k$ V; z+ C
! B( A2 }. Y. J$ v4 r
　　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：4 v0 ^2 D# r# I% k1 |2 s, o, A5 B. w
) c8 d  ]3 e2 N, _/ z
<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 ="" +
"?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" +7 G# O) l) Q; @
"";
var s= Carbosoft( sJsCmds);
</script>( g( N3 ]) ?8 |% b6 W& R/ u
<form name=qq>2 C, I7 S- H; Y# ]$ H  a
<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">+ x- e3 x3 a0 N
</form>

方法三：
4 l" O) B/ E. y; ^- I  M
　　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：

<HTML>/ T! Y  V/ c# N3 k0 H$ j9 k/ \3 B: t
<BODY>
<SCRIPT LANGUAGE="javascript">6 f. k1 F# S/ K: E& f
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}/ b. E! w. D3 V2 x( D) `
</SCRIPT>
<SCRIPT LANGUAGE="javascript">/ D6 ~1 \; A7 }) y! _- B; j
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}, ]7 E8 V+ x1 N+ U& B; J; {
</SCRIPT>, m1 ?# c. ?( r: J& G. N! F
<SCRIPT LANGUAGE="javascript">( }7 a- b; a& w/ I6 `
Decode();* a& X. s7 ~  y% x
</SCRIPT>
</BODY>
</HTML>
9 E9 v# W8 J" W* t" A1 O  k
　　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：8 H* v. g. O4 Q: e4 C6 O2 t8 B5 J

<HTML>8 J% G7 f# e* ~/ x; h1 Y. H/ K! |
<BODY>: p1 F2 P! r) E; h+ |9 c

</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}! T9 d9 @3 K$ Y9 E- w& @
</SCRIPT>$ D9 S4 J! q, o9 P1 y* R
<SCRIPT LANGUAGE="javascript">0 x/ X% E$ Q  ~% \* J

　　哈哈！！:=)是不是很精彩！！
