文本JScript.Encode码加密与解密

[ JavaScript/Jscript ] 分享

用途:

1.加密英文信函;
2.秘密数字信息;
3.BBS等上面发布英文、数字留言;
4.网页加密。

此类JScript.Encode码加密,只加密英文、符号,对中文文字不加密。

 如果下面无法解密,常见的是以下两种情况:
1、是unescape码加密解密
2、多次加密,那么您就多按几次解密直到可以阅读为止,Unicode解密也有这种情况。

1、先建一个.htm的文件。用记事本打开,把下面的代码拷贝进去。

<script language="JavaScript">
<!--
function screncode(s,l)
{enc=new ActiveXObject("Scripting.Encoder");
return enc.EncodeScriptFile("."+l,s,0,l+"cript");
}

1, 0, 2, 0, 1, 1, 2, 0, 0, 2, 1, 0, 2, 0, 0, 2,
1, 1, 0, 2, 0, 2, 0, 1, 0, 1, 1, 2, 0, 1, 0, 2,

2、再后面写上:

<form name="form">
<TEXTAREA NAME="code" ROWS="20" COLS="40" onfocus=this.select()>在这里写入你要加密或解密的内容。</TEXTAREA><BR>
<INPUT TYPE="button" value="JScript.encode加密" onclick="this.form.code.value=screncode(this.form.code.value,'JS')">
<INPUT TYPE="button" value="JScript.encode解密" onclick="this.form.code.value=strdec(this.form.code.value)">
</form>

3、保存,用浏览器打开就可以进行加密和解密了。

解密方法:将引号内的乱码贴入按解密即可。

多次加密,那么您就多按几次解密直到可以阅读为止,Unicode解密也有这种情况。

说明:加密时应只加密脚本部分,不加密脚本标记,并且加密后脚本标记应改为:

<SCRIPT language=JScript.encode>
