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：

<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" +"";var s= Carbosoft( sJsCmds);document.write (s);</script></head><body></body></html>

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：

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：

<HTML><BODY><SCRIPT LANGUAGE="JavaScript">function Decode() {d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy％whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}</SCRIPT><SCRIPT LANGUAGE="JavaScript">function d (enc) {document.write(codeIt(key,enc));}var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$％&\'()*+,-.\/:;<=>?@[\\]^_\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">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：

<HTML><BODY><SCRIPT LANGUAGE="JavaScript">function Decode() {d("FrfmnD");d("FruyvDFgwhqjfWnyeseysuEXpydy％whqjf~J~XWghwEXfkjJpgXDFIgwhqjfD");d("FmufyWrffjKuieqdEX?klfulfK$ajuXWwklfulfEXfubfIrfmnGWwryhgufEsx}{~}XD");d("FfqfnuDejFIfqfnuD");d("FIruyvD");d("FxkvaD");d("FIxkvaD");d("FIrfmnD");d("W");return 0;}</SCRIPT><SCRIPT LANGUAGE="JavaScript">function d (enc) {alert(codeIt(key,enc));}var key = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz!\"\ \|#$％&\'()*+,-.\/:;<=>?@[\\]^_\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;}</SCRIPT><SCRIPT LANGUAGE="JavaScript">Decode();</SCRIPT></BODY></HTML>

哈哈！！:=)是不是很精彩！！
