下面是一个VBScript，可以做你想要的但需要base64.exe
来自 http://www.fourmilab.ch/webtools/base64/
您将base63（已编码的）数据复制并粘贴到textarea中然后单击
将其保存到磁盘的解码按钮（作为base64 .enc）然后解码它
（作为base64.dec）。之后你可以将它重命名为
正确扩展名的文件名。
我使用这个变体来查看垃圾邮件中包含的base64文本。我用
使用文本编辑器查看解码后的数据，看它可能有害。
< html>
< head>
< title> base64.hta< / title>
< script type =" text / vbscript">
Option Explicit
子解码（）
''*
''*声明常数

Const cHTA =" base64.hta"
Const cDEC =" base64.dec"
Const cENC =" base64.enc"
Const cWSS ="％comspec％/ C base64.exe -d

Below is a VBScript that does what you want but requires "base64.exe"
from http://www.fourmilab.ch/webtools/base64/
You copy-and-paste the base63 (endoded) data into the textarea then click
the Decode button which saves it to disk (as "base64.enc") then decodes it
(as "base64.dec"). After which you can rename it to a filename with the
correct extension.
I use a variation of this to look at the base64 text included in SPAM. I
use a text editor to view the decoded data to see it it might be harmful.
<html>
<head>
<title>base64.hta</title>
<script type="text/vbscript">
Option Explicit
Sub Decode()
''*
''* Declare Constants
''*
Const cHTA = "base64.hta"
Const cDEC = "base64.dec"
Const cENC = "base64.enc"
Const cWSS = "%comspec% /C base64.exe -d
