asp字符串加密解密函数
摘要：
<%
A_Key=split("96,44,63,80",",")'定义密钥
'*********加密的过程*********
FunctionEnCrypt(m)
DimstrChar,iKeyChar,iStringChar,I
k=0
forI=1toLen(m)
iKeyChar=Cint(A_Key(k))
iStringChar=Asc(mid(m,I,1))'获取字符的ASCII码值
iCryptChar=iKeyCharXoriStringChar'进行异或运算
'对密钥进行移位运算
Ifk<3Then
k=k+1
Else
k=0
EndIf
c=c&Chr(iCryptChar)
next
EnCrypt=c
EndFunction
