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！！
: Y( P( o7 f4 N" A- V, H6 f5 o
) a4 ^( N% h# T- e- O/ y/ L
方法一：' K9 l  h: p- v  b% A0 U1 T5 U& G
6 F$ d( e( s! J9 V; T/ n9 M
$ u, ?( I& i/ R. J
　　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：6 j, N" I# N$ U5 |" w
* Z% J4 l1 K4 M8 ]8 T8 ]! S
<HTML>2 o& I; T0 W' n8 ]) p" J
<SCRIPT LANGUAGE="javascript">- `( {/ _  e* X+ d4 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"; M& R4 j  r. V& ?  k8 H* ^
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>
<BODY>
</BODY>& J5 F% L6 |' Y8 H# n1 ]% f4 |; o
</HTML>1 P. _# b1 j. u. }
8 G& g! b0 C* }( x) y: y
　　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：0 z$ b# ^" \8 `& E# f; }" y

<HTML><SCRIPT LANGUAGE="javascript">0 G0 ?" i2 E0 L% |1 J
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;3 O. H" X6 ~7 s- z4 h
NewWords = unescape(Words);
NewWords=NewWords.toString();# O+ i3 P, [% A
function password(){4 Y- g7 [! S; N
document.pw.txtpw.value=NewWords;
}: C$ w" H* z. O; Y7 d
</SCRIPT>* X* K- D2 c( n! g3 E
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>% y7 p5 g& y* A5 Y% L
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>
</HTML>

方法二：( m3 \& ?+ G! E# m. @4 w5 L& {  L
9 D8 _0 V8 k  t0 q/ d! G# W
　　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 ="" +# e& o0 f- H; w- X( G; [3 Q
"?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" +, V7 I2 L' {, I6 o& O. r, @7 X
"";% q( U  N0 N. v1 x$ B& {
var s= Carbosoft( sJsCmds);: G; v. Q9 D% H. d: A
document.write (s);4 M! Q" Y% J% i7 ]* I
</script>
</head><body></body></html>+ \" K* i2 o0 ~6 c  J
8 l# ~( ~+ D+ p: x8 I' w* a: g
　　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：6 j7 G0 ?9 J, C/ u

<script>+ Q& _6 e6 S, {6 \
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" +$ b8 s9 w9 b.

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& V$ `2 l) V8 ?  I
+ l  A* w2 \/ r% _% T) u3 {
<HTML>
<BODY>1 y$ l& m: w/ h& ?
<SCRIPT LANGUAGE="javascript">+ I" x9 p2 R' n$ m5 b
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}) C" n( @3 i* ]# V9 w: Z
</SCRIPT>8 h, ~! ?6 x/ i! @! h
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}
</SCRIPT>  q# H  v5 ?: [& D
<SCRIPT LANGUAGE="javascript">
Decode();( \' b+ |- v# j( l2 I
</SCRIPT>
</BODY>, Y- e+ g6 _" Z( R# }$ L
</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：

<HTML>/ c( Q, N5 J; k# s4 E
<BODY>  I  e6 Q  D0 H( X( S
<SCRIPT LANGUAGE="javascript">8 T) j# g+ l9 i, h) i; G
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}+ A$ D, x; f# Q# Z
</SCRIPT>. A# d: T$ {4 D: u" v3 i# p
<SCRIPT LANGUAGE="javascript">* Y2 V, z2 ^: l' @1 W% X2 W
function d (enc) {alert(codeIt(key,enc));}* M6 ^3 q& ~" Z( Y
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;}6 M; Z4 s& Z# i7 A, ]
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();- B5 k: s: G( j4 ?' @% r9 D
</SCRIPT># Z, d" c( p: S5 |% T4 S1 s
</BODY>
</HTML>
  R2 {/ I: S' _& [  z
　　哈哈！！:=)是不是很精彩！！
