You have to use/learn classes from System.Security.Cryptography namespace.

Hi use this for simple one

Public Function SimpleCrypt(ByVal Text As String)
        ' Encrypts/decrypts the passed string using 
        ' a simple ASCII value-swapping algorithm

        Dim strTempChar As String, i As Integer
        For i = 1 To Text.Length
            If Asc(Mid$(Text, i, 1)) < 128 Then
                strTempChar = _
          CType(Asc(Mid$(Text, i, 1)) + 128, String)
            ElseIf Asc(Mid$(Text, i, 1)) > 128 Then
                strTempChar = _
          CType(Asc(Mid$(Text, i, 1)) - 128, String)
            End If
            Mid$(Text, i, 1) = _
                Chr(CType(strTempChar, Integer))
        Next i
        Return Text
    End Function
