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！！

/ l5 m: H6 ~/ j$ ^* F" W# U, V
方法一：7 D/ Q) n% ^( q' u* P- w# k8 U
) S$ a2 t. q' u; S+ z8 a
# C0 Y9 D* c; m& K6 C
　　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, Z$ b1 _7 h9 d
- o( T/ C& N- R! H! k
<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"( G' ~+ K- `* }$ e# N
var NewWords;* c# t2 E) G: _/ K! s" _
NewWords = unescape(Words);
document.write(NewWords)
</SCRIPT>
<BODY>) v0 }/ P9 f0 ^& F- ~! M$ a
</BODY>
</HTML>
0 N- {  r2 }) D' D: b
　　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：
2 |+ p1 V: s5 l1 n/ T6 v6 ]# h
<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": S$ A9 L; `6 r$ V
var NewWords;! q6 N' M/ \# X
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;2 x$ n' e9 d1 o
}' I+ I) [0 n& b/ s- q
</SCRIPT>, y2 K) b) J. m% Y. k* D) |: x$ P0 A
<BODY>
<form name=pw>
<input type=button onclick="password()" value="解密">
<br>0 g2 c4 R8 J' h" b" E- u
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>: _  e4 O' j- M8 F; c; h0 U
</BODY>9 z) `2 J! L1 q/ H; I
</HTML>
2 {& @1 L" Z: T  L  j
方法二：
& [, x/ a, }. E  n9 L
　　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：) w& M) l5 y/ e: R& j# D. _5 q

<html><head><script>) o1 c2 g4 Q+ @( q0 _6 l
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 ="" +9 e! Y2 c0 b7 R( T- 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);
document.write (s);: s* R1 B1 {! N* k! S
</script>$ U2 i" ~. B$ p+ h1 b, H3 ^( d& _! O
</head><body></body></html>$ m" K  ?: a% t  a) u$ T" T

　　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：
8 c8 c" |7 m, Q
<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 ); }$ g! [3 z* V" I. O1 w% i* V# c& {* S
var sJsCmds ="" +: h9 b6 o" b; `) A2 f% @$ m% U2 p% 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" +. v( o) Y+ J- ^" S1 j9 h: Z( l
"";
var s= Carbosoft( sJsCmds);$ }% g5 u1 B9 L4 A/ {
</script>
<form name=qq>" _% i  s% D4 Y# |* R/ s
<textarea name=ww cols=100 rows=10></textarea>
<input onclick='ww.value=s' type=button value="解密">  i  g0 P6 @! u* R& a; Z  v
</form>

方法三：
" k$ O: ]$ K0 W, _
　　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：
8 W% `, R' R) }4 Q! \: D$ i4 x; i
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">7 U( n/ t' J' J8 }9 z" t3 {
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}/ G# D; h9 p; t% K' {9 W
</SCRIPT># @) K) ~2 J7 ]
<SCRIPT LANGUAGE="javascript">8 j! ?  L/ J1 j9 Y
function d (enc) {document.write(codeIt(key,enc));}$ j/ j0 |* t) \3 e
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;}2 W5 J0 s7 `+ |! o2 ]0 q2 w" t
</SCRIPT>: {. o! P0 L( m' D+ A
<SCRIPT LANGUAGE="javascript">

</SCRIPT>  ?. S2 A; R7 J' t8 [' E8 ~2 F; [# J
</BODY>
</HTML>, A; E& e4 T1 H9 V; {& G, l

　　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：" ]/ P7 @# `, K5 W$ t9 _
% _  k+ u$ c) `; M; }9 x0 b6 ~
<HTML>
<BODY>
<SCRIPT LANGUAGE="javascript">: f8 S) J# y: Z. B. r3 N2 m0 Y

</SCRIPT>
<SCRIPT LANGUAGE="javascript">' [" Q+ h8 y7 J; l; r
function d (enc) {alert(codeIt(key,enc));}/ {7 ~% `0 a! ^8 F+ D+ M
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>8 u2 e0 `2 u) R0 z

　　哈哈！！:=)是不是很精彩！！
