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！！: q2 Y0 M3 [6 \9 P) X$ C

7 P0 C% J7 \6 |) W- x( G
方法一：1 k2 A) \3 ?3 L( M, g' ^& ]7 |
; G& X8 p* w2 B1 @

　　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 v6 f; r. v/ q, m4 p
<HTML>" g# @& P1 M! V! n  J' P" d! M, g
<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"% R% j) L2 @9 h4 I* s& ~7 j5 \2 t6 K& f
var NewWords;* |% J2 ~+ J3 ]! A
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>
<BODY>) |3 F* D0 C/ z) H9 r
</BODY>
</HTML>( o6 e/ g7 b6 m! P% Z: d
  F) J) X5 n! c/ G7 Q
　　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">
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);3 q) ^* \; `0 z" ~1 l
NewWords=NewWords.toString();
function password(){1 |. R" s+ ?) L1 D
document.pw.txtpw.value=NewWords;0 L# h3 W) O; `; N5 P- R/ F; R
}2 a5 E+ G7 |# l3 |
</SCRIPT>
<BODY>
<form name=pw># r% u/ }' Q$ v
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>  ?0 F5 {3 g5 @3 U
</form>1 S" @6 ?6 d- S3 A2 H. h; V9 ~
</BODY>
</HTML>, X( ]* W3 f8 `1 D* H8 X5 S

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：7 I- d. K8 `* S4 X2 X4 ?

<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 ="" +- N+ g8 F, G0 z. O6 J" w4 n
"?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);! t& r8 m6 L0 X/ f  r# X1 e1 L8 I3 ?
document.write (s);/ d/ }/ F* |  {% m! t7 M" C
</script>
</head><body></body></html>1 _/ H! c5 K4 H& H. {8 z

　　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：
5 _) ~, S" {* d0 s
<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 ); }3 P: i! Z' a, J4 r- O$ J3 T- m
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" +% x9 s, T!

<input onclick='ww.value=s' type=button value="解密">
</form>7 f/ g! q/ C+ Q, E; _

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：/ y% \- s! y5 }, S

<HTML>3 E3 j5 N$ F# A9 m  e  k$ a
<BODY>
<SCRIPT LANGUAGE="javascript">" |7 x$ a6 X! ?$ h2 [, H( ^
function Decode() {5 {; r0 V4 \- y( n/ n
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>% `$ z1 s( p7 i% V
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\t\`{}~\n";function codeIt (mC, eS) {var wTG, mcH = mC.length / 2, nS = "", dv;for (var x = 0; x < eS.length; x++) { wTG = mC.indexOf(eS.charAt(x));if (wTG > mcH) {dv = wTG - mcH; nS = nS + mC.charAt(48 - dv);}else {dv = mcH - wTG;nS = nS + mC.charAt(48 + dv);}}return nS;}8 ?9 h3 K+ O' i$ `2 f
</SCRIPT>2 u5 n- S+ Q1 _; N
<SCRIPT LANGUAGE="javascript">6 l7 Z+ h% e3 s0 o& E- |# {
Decode();" y0 Y" w! K7 m& }# a% G
</SCRIPT>- E- m6 D" U  `! h3 K
</BODY>
</HTML>8 f( E6 }. i. M/ [! ~
9 \" L2 |$ r: i, R) o
　　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：
* V* b+ P0 G, k& @+ B
<HTML>6 ?4 ~1 u9 v1 H" t# ?
<BODY>
<SCRIPT LANGUAGE="javascript">  r$ G, o& f3 n: e, d5 M
function Decode() {! u* l3 c! t) d9 g" D: s
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
function d (enc) {alert(codeIt(key,enc));}# b: A) A8 G0 G2 f8 g
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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">% ?3 V0 o# g3 d
Decode();
</SCRIPT>& w: j) k; ]' G$ ~5 P2 _- h6 N
</BODY>/ q0 a% ^6 P5 g: p; J% ~3 @
</HTML>' `/ z/ c! H- D& Z( u+ o: K2 t7 E

　　哈哈！！:=)是不是很精彩！！
