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：

　　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：

　　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”>
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);
newwords=newwords.tostring();
function password(){
document.pw.txtpw.value=newwords;
}
</script>
<body>
<form name=pw>
<input type=button onclick=”password()” value=”解密”>
<br>
<textarea name=”txtpw” cols=”100″ rows=”100″></textarea>
</form>
</body>
</html>

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 =”” +

“”;
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！！
