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：% P1 {& T6 F  n+ ?: {6 |
$ S& _  A+ J: E! R% Y
3 j/ H# Y: W; e& O7 n, u
　　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：+ ^* c' ?$ j8 ]* v

<HTML>. s. D! q: w5 I& p' [7 t
<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"* v# T4 b( E4 g8 [
var NewWords;
NewWords = unescape(Words);
document.write(NewWords)* t& F* v* W+ U! l5 {0 p
</SCRIPT># g8 u' Z, `5 W* h; y
<BODY>; _. ]. c/ _, l; f+ N8 n0 G
</BODY>
</HTML>
9 ?5 p! C% G7 J2 ]" `6 k
　　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：- e7 p  S# g" {

<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);$ f- o. x. F2 J7 k$ v* ^
NewWords=NewWords.toString();
function password(){9 I3 N* n- i% {: R5 }1 j$ q
document.pw.txtpw.value=NewWords;5 n) {2 R; k7 g
}
</SCRIPT>
<BODY>
<form name=pw>+ b; V( Z6 J5 M% I/ W8 f( P
<input type=button onclick="password()" value="解密">* D( L+ g. E( Y0 Q; @, y, a
<br>& Q8 A: i) D1 C9 o1 n- P
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>5 o6 E" V' ~# X  P- V+ {- z
</BODY>: h$ k" j# [+ w) N# W; y1 \/ d5 [
</HTML>
4 `1 v! X8 T% b/ n# `5 |
方法二：
# X) f; X7 o3 s6 t
　　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：$ f% O0 t5 l- d  t" F& q/ l

<html><head><script>) u* L( ?0 w% \" u- p; C8 V6 |
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 ); }/ g: Z% P4 c. D# g# }0 g
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" +
"";! q$ @. C9 i0 G; B+ ~& t4 U- `
var s= Carbosoft( sJsCmds);- E: m# W0 p; z3 r) d4 G$ k
document.write (s);
</script>
</head><body></body></html>- U, ~* A$ r7 n; a. y' A2 J

　　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>
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 ); }( _8 K# ~" D* x* t9 s: E4 P
var sJsCmds ="" +( _9 F; M, T: L" R
"?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" +3 K# c$ U8 Y& c7 Y

方法三：. ^; w; Z- k: G$ j( m) E: s6 I
/ ^: e: C) C* i6 \
　　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：/ Q) K0 k' I% V; T& H5 G8 ^
# Z. w; {0 {) C5 m9 `
<HTML>; \" F7 {8 {3 d3 V3 G4 A
<BODY>
<SCRIPT LANGUAGE="javascript">; `  J! D: }( y1 R* T
function Decode() {  {4 {% Z4 d- W% \# o
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>
<SCRIPT LANGUAGE="javascript">! o. I) v1 {* J: ?, @  _
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}$ G- J/ A: D1 S+ [
</SCRIPT>
<SCRIPT LANGUAGE="javascript">
Decode();
</SCRIPT>
</BODY>
</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：# ~. B$ f, r8 h$ k1 |+ t+ N
0 v  @, @4 u3 d( B
<HTML>* {; ?) H, Y# z2 j: V
<BODY>
<SCRIPT LANGUAGE="javascript">

</SCRIPT>
<SCRIPT LANGUAGE="javascript">+ f! w0 m0 v; f
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;}9 y9 l4 D' d!

　　哈哈！！:=)是不是很精彩！！
