Xor Encryption

[Nean]

Can someone please explain this to me? I've been screwing around w/ it, and I managed to get:

Code:

Private Sub Form_Load()
    Dim Test 1 As String
    Dim Test As String
    Test1 = 0
    Test = 1
    lblLabel1.Caption = Chr(Asc(Test)) Xor Chr(Asc(Test1))
End Sub

But I still don't really get it. How can Xor be used practically? Etc, etc. Like lets say I wanted to encrypt a password with Xor, how would I do this?
