ASP 自编加密、解密函数

一个加密、解密函数，例如：

function jmjm(string)
for i=1 to len(string)
str=mid(string,i,1) XOR 99
next i
jmjm=str
end function

===============

function mis(preString)

Dim texts

Dim seed

Dim i,length

prestring = trim(preString)

length = len(preString)

seed = length

texts = ""

for i = 1 to length

seed = int(94*rnd(-asc(mid(preString,i,1))-seed*asc(right(prestring,1)))+32)

texts = texts %26; chr(seed) %26; chr(int(94*rnd(-seed)+32))

next

dim dist

dist=""

for i = 1 to len(texts)

if asc(mid(texts,i,1))>64 and asc(mid(texts,i,1))<123 then

dist=dist+mid(texts,i,1)

end if

next

mis = dist

end function

Function EnPas(CodeStr)

Dim CodeLen
Dim CodeSpace
Dim NewCode

CodeLen = 30
CodeSpace = CodeLen - Len(CodeStr)

If Not CodeSpace < 1 Then
For cecr = 1 To CodeSpace

Next

Dim Been
For cecb = 1 To CodeLen

Next

NewCode = Empty

For cec = 1 To Len(CodeStr)
NewCode = NewCode & CfsCode(Mid(CodeStr,cec,3))
Next

For cec = 20 To Len(NewCode) - 18 Step 2
EnPas = EnPas & Mid(NewCode,cec,1)
Next

End Function

Function CfsCode(Word)
For cc = 1 To Len(Word)
CfsCode = CfsCode & Asc(Mid(Word,cc,1))
Next
CfsCode = Hex(CfsCode)
End Function
