Private Sub Comman1_Click()
Dim str1, str2, str3 As String
str1 = "王宇虹"
str2 = Encrypt(str1, 188, 24)
MsgBox str2
str3 = Encrypt(str2, 188, 24)
MsgBox str3
End Sub

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
