下面一段VB的程式用Delphi怎么写,或对应的函数是什么,恳请指教!
Private Function Encrypt(ByVal strSource As String, ByVal Key1 As Byte, _
ByVal Key2 As Integer) As String
Dim bLowData As Byte
Dim bHigData As Byte
Dim i As Integer
Dim strEncrypt As String
Dim strChar As String
For i = 1 To Len(strSource)
‘从待加(解)密字符串中取出一个字符
strChar = Mid(strSource, i, 1)
‘取字符的低字节和Key1进行异或运算
bLowData = AscB(MidB(strChar, 1, 1)) Xor Key1
‘取字符的高字节和K2进行异或运算
bHigData = AscB(MidB(strChar, 2, 1)) Xor Key2
‘将运算后的数据合成新的字符
strEncrypt = strEncrypt &
ChrB(bLowData) &
ChrB(bHigData)
Next
Encrypt = strEncrypt
End Function

End Function
