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：
0 h" A! s! s0 d5 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：( ^; m4 I# U% [% ^8 L& ^
( A" _5 B9 m; ~% A+ y
<HTML>
<SCRIPT LANGUAGE="javascript">: A; {) M& l  w3 }1 f2 V8 a
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;, j, w+ |& S1 L! X0 _0 q
NewWords = unescape(Words);
document.write(NewWords). }& x0 J& C3 c8 F, T2 g, i! J5 P  q
</SCRIPT>
<BODY>. K& M" u1 F1 u% S4 [* w
</BODY>5 P. }6 K: S* e: C
</HTML>+ X: m* Z0 D( L5 ~8 D; Q- u" @

　　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">( j, W& E3 ^( r/ n
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"( S3 ]3 j, Z+ Z% c( S& t5 C
var NewWords;' N! }* Q% M, P8 G; X
NewWords = unescape(Words);; H- s; W$ @, {
NewWords=NewWords.toString();
function password(){$ ?" e* s: R3 V' J5 }
document.pw.txtpw.value=NewWords;
}3 V( w& p, r8 ~3 b/ w- Q
</SCRIPT>' H9 c: n5 L8 p/ u. ~9 d
<BODY>* R5 G- o9 o: W5 i3 D
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>$ J% T- M1 f5 y" z* K
<textarea name="txtpw" cols="100" rows="100"></textarea>1 O# y# b9 v2 B
</form>
</BODY># x2 i. w. A" m* Z+ F
</HTML>
4 V" `  D& a  o! K; j% e
方法二：
! \/ l$ F* R3 D  h0 o
　　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：

<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);+ ^" ?5 `- d) u9 W: ^+ s
</script>( ^% H& U0 o3 v. \; b9 T! Z
</head><body></body></html>
& u2 m! s  b1 d/ @
　　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：
+ L" K* ~  A; y9 Y
<script>6 J. ?6 ?) [: z3 K$ _! h! e
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 ); }/ q" w7 I/ L* f9 {4 J, Z% q0 N9 V
var sJsCmds ="" +; Q; ?* H2 _. W5 A( {) [
"?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);6 Z# V4 ~2 d" ?. n: D8 A$ X
</script>1 i* B; t! u, ^) H: B' z
<form name=qq>
<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">
</form>( h0 ]8 u" E% Y/ @5 p' f
8 Z7 S5 e* R6 `2 W

方法三：
. n1 A( ~  x& L% s
　　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：! Y$ e: e; w- p1 K+ h' c% n

<HTML>+ F, W. L; T0 K
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {4 N4 G; k# S; l& X# B" {4 v
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}% ?( _6 O/ r2 R2 o+ Z* n" b) }
</SCRIPT>" `3 Y( }/ N( Q& v
<SCRIPT LANGUAGE="javascript">: y1 N' ^7 q4 O6 p  O  X
function d (enc) {document.write(codeIt(key,enc));}8 t) e" w+ h. i0 ^: p$ K3 H; d
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}% j4 B7 c' B8 I
</SCRIPT>
<SCRIPT LANGUAGE="javascript">. t4 t) x4 p, {& h
Decode();& O, |  M6 s& f
</SCRIPT>
</BODY># y4 y3 q! G5 y+ J8 O
</HTML>4 e& y. q1 Z1 G7 O# b  G
7 J! q5 V9 [) C; {0 r
　　还原的时候，也必须每行单独解密，用下面的方法可以看到源代码：: P5 n( Y8 T& {# m0 Y, o/ e
6 n; k: P5 [' k& ?
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {  |2 c( J" t/ s2 ~, z
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>" I$ S+ ~: |+ f
<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;}8 U) |" g, t. g* t' T, Z! Y
</SCRIPT>
<SCRIPT LANGUAGE="javascript">% w8 v0 [- ^0 |) t& q4 N( y
Decode();( o- u1 k1 ]% d! O* g; W
</SCRIPT>
</BODY>
</HTML>! k) Q7 ~1 p1 J* V

　　哈哈！！:=)是不是很精彩！！
