    你好!  
    我学vbs也有一小段时间了,最近看到一本书上讲vbs脚本的加密,就自己试了试,可是有一点问题,低级的语法错误我都自己修正了,可脚本运行后不起作用.所以想请教你一下.脚本的原理是这样的:它把代码转换成16进制,然后再写个解密代码,通过这个解密来执行加密的代码,将字符串成16进制的代码如下:  
Function str2hex (Byval strHex)  
For i=1 to Len(strHex)  
sHex = sHex & Hex(Asc(mid(strHex,i,1)))  
 next  
 str2Hex = sHex  
end Function  

解密的代码如下:  

Function hextostr(data)  
Hextostr = "Execute"""""  
C= "&Chr(&H"  
N= ")"  
Do while Len(data)>1  
if IsNumeric (Left(data,1)) then  
Hextostr=Hextostr&c&Left(data,2)&N  
data=mid(data,3)  
else  
Hextostr=HextoStr&C&Left(data,4)&N  
data=mid(data,5)  
end if  
loop  
end Function  

解密代码好象有点问题,请帮忙指正,我实在找不出  

整个成品就是:  

on error resume next  
set arg=wscript.arguement '声明外部参数  
if arg.count=0 Then wscript.quit '若无参数则退出脚本  
set fso=creatobject("Scripting.Filesystem Object") '声明fso组件  
when fso.opentextfile(arg(0),1,flase)  
data = readall:.close'读取文本内容  
if err.number<>0 then wscript.quit '如果发生错误，则退出  
with fso.opentextfile(arg(0)&"*.vbs",2,true) '将转换好的写到一个新的vbs中  
if err.number<>0 then wscript.quit '如果发生错误，则退出  
.writeline "Execute(Hextostr("""&str2hex(data)&"""))"  '执行解密并执行解密后的代码  
.writeline "Function hextostr(data)"  
.writeline "Hextostr=""Execute"""""""""""  
.writeline "C=""&CHR(&H"""  
.writeline "N= )"  
.writeline "Do while Len(data)>1"  
.writeline "if IsNumeric (Left(data,1)) then"  
.writeline "Hextostr=Hextostr&c&Left(data,2)&N"  
.writeline "data = (data,3)"  
.writeline "else"  
.writeline "Hextostr=Hex to str&c&Left(data,4)&N"  
.writeline "data=mid(data,5)"  
.writeline "end if"  
.writeline "loop"  
.writeline "end function"  
'把解密函数写进去  
.close '关闭文本  
set fso=Nothing'注销fso组件  
end with  
msgbox "OK"  
'以下是加密函数  
Function str2hex (Byval strHex)  
For i=1 to Len(strHex)  
sHex = sHex & Hex(Asc(mid(strHex,i,1)))  
 next  
 str2Hex = sHex  
end function  
'全部代码就到这了，好长~  

书上说,把要加密的vbs脚本拖到这个脚本上就行了,不过我没有成功,不知道那里有问题,请帮帮我,谢谢~ 

上面的代码注意的几个情况：
1、set arg=wscript.arguements
后门有个s
2、set fso=creatobject("Scripting.Filesystem Object") '声明fso组件
应该是filesystemboject
3、.writeline "N= )"
对于需要输出N=")"用vbs输入"（双引号）的方法就是用两个""
.writeline "N="")"""
4、.writeline "data = (data,3)"这里少个mid
基本上就这些了
do.vbs保存为do.vbs ，将要加密的js文件拖到这个文件上就可以
