which form of encryption is used in this asp function

问题

Below asp function is used to encrypt passwords.

Function EncryptPassword(vPwd)
    vTempPwd = ""
    EncryptPassword = ""
    For i = 1 To Len(vPwd)
        vTempPwd = vTempPwd & Chr((255 - Asc(Mid(vPwd, i, i))) / 2)
    Next
    For i = Len(vPwd) + 1 To 10
        vTempPwd = vTempPwd & CStr(i - Len(vPwd))
    Next
    EncryptPassword = vTempPwd
End Function

Can anyone just tell me which method of encryption is this? I want to use the same method of encryption is asp.net.
