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：

. }- R2 ?0 s2 P6 i" a
　　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：
7 w! W- O$ [0 \5 J9 G1 D
<HTML>$ `1 Z/ R* y& ?' o" A
<SCRIPT LANGUAGE="javascript">, V2 E) h' d" c2 W
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". }8 t# y* z! o; d
var NewWords;0 P% f* }* b( e3 G5 X& W/ ^4 m
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>3 m& ?  C3 T4 J* N
<BODY>
</BODY>
</HTML>
1 D  [- ?1 G9 S' x0 n4 h
　　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">; k# U  K' n  Y  ^
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"3 E8 Z% \0 d8 h* c# |! n
var NewWords;
NewWords = unescape(Words);: U/ R2 d, f7 E! Z! Q. o
NewWords=NewWords.toString();* G. f9 X% F4 T
function password(){
document.pw.txtpw.value=NewWords;
}
</SCRIPT>2 w* v  I, ?8 \& u1 J1 \' y
<BODY>! l+ A- B1 E* Z1 `- O
<form name=pw>) [8 L( y5 ]& y+ R0 n% T7 ]
<input type=button onclick="password()" value="解密">
<br>: W; R# B& ~) }0 \7 [, }2 U
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>; h  _6 e( Y! {, Y0 S
</BODY>0 Q( w/ F1 x' X6 R3 H8 ]
</HTML>8 T; n* n1 c) Y( B) a+ [, g) E6 ^- G

方法二：' O+ y8 H3 W4 v" H" Q* \' L: j* F! N

　　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：1 E3 `3 q. i8 n* y2 }

<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 ); }
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" +
"";
var s= Carbosoft( sJsCmds);
document.write (s);
</script>8 g) q3 j, e3 |6 U7 J% ?
</head><body></body></html>: @" U( S, m1 N- K$ H
; h; P. p8 W8 b! |2 V
　　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>) u. p4 U& M; V9 _. P; h( I
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" +
"";
var s= Carbosoft( sJsCmds);
</script>' a: c% M2 r! o: P
<form name=qq>) a( b. m, p7 O% l# I4 g$ `
<textarea name=ww cols=100 rows=10></textarea>9 J4 `$ T  U% B3 l
<input onclick='ww.value=s' type=button value="解密">
</form>9 B* k  d0 n* k
2 a% _: ~* I# w& a# s

方法三：' k$ [  z( L& O: z3 b

　　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：
+ e2 F. t2 M: F
<HTML>% Q3 S" S, T6 w9 I' }0 j
<BODY>
<SCRIPT LANGUAGE="javascript">  ~. X, a6 W% E% R# I) `
function Decode() {5 o& i# z; m/ s2 {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}' y3 F3 f% e3 x: A$ A' _2 R! [2 D  O
</SCRIPT>( y3 ?% y/ R# j  u
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}. F  R4 c& c  q7 h: N. e4 J
</SCRIPT>) E/ B. d6 \' l$ m7 u( \
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>
</BODY>
</HTML>, g5 O# Q3 Q; z7 }3 {
7 X; \0 s9 J' l! a( `
　　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>  t" J9 J1 Z; G6 m- M9 [5 d" M
<SCRIPT LANGUAGE="javascript">
function Decode() {7 h% D1 |4 G1 x2 P6 [
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>+ O0 R! g# K2 @) J+ d+ i' a' Z
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}
</SCRIPT>9 ]4 S0 K0 `" t+ E& R

　　哈哈！！:=)是不是很精彩！！
