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：

( h& [! }4 f% j7 ~  z# X) Q. j; Z
　　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：8 L4 k/ Y( o9 a/ P, x; z
) H* c) D' R% F) I2 C; w
<HTML>
<SCRIPT LANGUAGE="javascript">2 g8 y  o) z3 U! w' L$ S) Q$ U
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);
document.write(NewWords)
</SCRIPT>, g! @" _% K' D4 y
<BODY>
</BODY>
</HTML>/ w5 b, l) h8 W0 ]/ U+ N! M

　　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">" f* v  D7 O! i- k* m, R
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"3 S' w; ]  R0 o
var NewWords;
NewWords = unescape(Words);8 a; I/ i! T! x7 w* J
NewWords=NewWords.toString();6 W. S; I* L) p9 x
function password(){- ~3 u6 \0 d9 i# \
document.pw.txtpw.value=NewWords;
}
</SCRIPT>
<BODY>  F( M4 c) e+ G8 c
<form name=pw>( _2 k& [4 q& X# H/ y+ t3 F
<input type=button onclick="password()" value="解密">
<br>
<textarea name="txtpw" cols="100" rows="100"></textarea>* A( B  ~! X; S. W! P2 V3 ^
</form>: D6 ^; Z2 F- g
</BODY>
</HTML>( m: E  u) F: h7 V' N; F7 V0 v. r

方法二：
0 j. f& X: r- T4 M$ a( C
　　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 ); }4 R0 p: [' I( F* A! C
var sJsCmds ="" +6 m( b- K$ d* _% Z
"?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" +% p6 A! l. M) r; ^+ b4 e4 h
"";0 Q- v5 T" r/ x& i1 Y
var s= Carbosoft( sJsCmds);3 t* ^0 g% R/ Y/ x- M2 G
document.write (s);
</script>5 m. o7 u+ ?  b+ I3 \1 v4 S; w  r
</head><body></body></html>! O2 H0 U: B$ g% O6 {4 U

　　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：  V. L! K: |! \6 A7 Q

<script>( {8 j; ]2 {; Y3 z. H7 I2 O
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 ); }7 G) i  C, z5 g% C# B* A4 x0 h
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" +

</form>

1 ]1 G" P1 U! P/ b( P
方法三：# g8 B" M' O) [2 _! e

　　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：
" r' O+ C% a3 ~9 z. T
<HTML>4 K, B, m- W+ g5 g3 @9 O; x
<BODY>
<SCRIPT LANGUAGE="javascript">4 i9 C1 t6 `2 D4 @/ K- L0 c
function Decode() {0 {: M, o; c0 `; E7 s" X& `
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}
</SCRIPT>' ~! t% w1 W5 U' P) T- F5 z0 ?9 d
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}' ~0 _) M' A2 K. m- v8 u
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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>& q9 L" h$ ]. `  D$ h7 @+ L
<SCRIPT LANGUAGE="javascript">/ H& \% @2 Y- p" Z
Decode();
</SCRIPT>% G* i+ S/ E& L9 b! y
</BODY>- p# e7 S. a. P; ]  ~, M
</HTML>, v  z# K2 L& D+ c$ y

　　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：
6 {2 w  q! N  y
<HTML>" A0 G) l( S7 L4 }- |
<BODY>5 W$ S7 P. }+ U, p
<SCRIPT LANGUAGE="javascript">8 d) f3 ~3 y$ j9 J6 Q2 P7 M; M
function Decode() {. T$ l, e" I( u7 W) P( X0 k
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}' h, ]5 H3 L5 g: f
</SCRIPT>
<SCRIPT LANGUAGE="javascript">' U" P. L& T' H- d
function d (enc) {alert(codeIt(key,enc));}1 {# a9 @( p% O: B
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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;}1 L% p1 c& v* }, `% H- I* e1 L
</SCRIPT>( ~. m' F# ^4 W; p' d
<SCRIPT LANGUAGE="javascript">  o4 y( H& U" I
Decode();
</SCRIPT>
</BODY>- p" i: ]- M7 |: a. u( N
</HTML>

　　哈哈！！:=)是不是很精彩！！
