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！！

1 R0 ?% }# }9 j0 n! w1 O
方法一：

# ~, H% e" z6 h, R+ Z( ]# {" x
　　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：/ e0 U$ g+ H& h1 y/ T' B  `6 {& E

<HTML>
<SCRIPT LANGUAGE="javascript">4 Q" X3 N. h- n. I( a* n
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;, t" d9 v+ Y7 ?
NewWords = unescape(Words);
document.write(NewWords)2 p+ |  W9 J! H. ~& Z2 O' d
</SCRIPT>
<BODY>
</BODY>' w  M# |! M8 o
</HTML>  S. q  u4 [( z1 G

　　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：
1 {" D) {$ ^. W- S1 n# S
<HTML><SCRIPT LANGUAGE="javascript">4 q8 H; A4 o. t: J. V3 Q1 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"- U5 r  u7 R. v0 {4 Y. K. p
var NewWords;
NewWords = unescape(Words);
NewWords=NewWords.toString();
function password(){
document.pw.txtpw.value=NewWords;3 \3 h/ k+ c3 S1 d3 [
}
</SCRIPT>
<BODY>
<form name=pw>8 s9 x" A9 B- a9 O$ N
<input type=button onclick="password()" value="解密">
<br>* o, G% `! i  i) I
<textarea name="txtpw" cols="100" rows="100"></textarea>
</form>
</BODY>
</HTML>1 t2 `0 U0 w3 I% \/ O
4 b* y4 d3 _7 H  G3 l
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：: r" w* ^& G, F( W$ k
) p7 N( ^& S& F; C' x" C
<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 ="" +
"?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" +$ x% @1 \( v$ J$ H. W( T) {
"";
var s= Carbosoft( sJsCmds);
document.write (s);# f/ w  r" j) [* y& v6 Z: G, K( H
</script>
</head><body></body></html>
! [, q) U. D9 X7 [9 A2 o! {" u, A% x
　　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：
" Q* B# Z' f$ l
<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 ); }: s0 X6 N; X" u$ u
var sJsCmds ="" +# f2 d* D; D; S" ^$ y7 i
"?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" +

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：; @  f  u$ n' i0 I) c8 V3 U4 q
: d/ J$ r2 A" P) l" ~
<HTML>) V" m) _, M$ `# x- l
<BODY>; o9 B( T' c. U& B# F. a
<SCRIPT LANGUAGE="javascript">; p1 ], Y3 c0 s' K8 \) g
function Decode() {7 \# L7 l) ]/ P7 ~6 P7 s5 [2 O
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}0 u: [! M) E+ I! X6 t1 F) R/ X
</SCRIPT>9 D; h! X0 `9 a) ^4 S
<SCRIPT LANGUAGE="javascript">
function d (enc) {document.write(codeIt(key,enc));}
var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$%&\'()*+,-.\/:;<=>?@[\\]^_\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>
<SCRIPT LANGUAGE="javascript">! r& F( _: i, n2 y- ?6 i
Decode();7 ?' T6 m( @. ~: b4 r) @
</SCRIPT>
</BODY>
</HTML>
) i$ c5 v! p0 z- Z
　　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>
<BODY>
<SCRIPT LANGUAGE="javascript">
function Decode() {
d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy%whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}$ z  I6 Z' W! a; \" O$ X0 ?1 T6 H
</SCRIPT>' J  h# z, Y. t) E. ~& e% {
<SCRIPT LANGUAGE="javascript">8 h- T, _/ X6 n3 R% @0 J- |. s! i$ z
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;}1 i  O/ ~, k3 Y, t1 J
</SCRIPT>
<SCRIPT LANGUAGE="javascript">" @5 {9 k. T" R

</SCRIPT>' D" v0 K1 }8 a" t
</BODY>" S4 ~0 P! I( p, A- Y
</HTML>
! }; _  m( W5 t8 R: o
　　哈哈！！:=)是不是很精彩！！
