Feedback for inherited code using Xor operator

I'm quite new to VBA and have inherited a VBA code and the person that wrote this code protected the sheets with the below sub and function.

Is anyone able to decode the below? Seems like he is using special characters but this code is too advanced for my current understanding.

Any guidance or feedback would be appreciated.

Public Sub makeSafe(ws As Worksheet, safe As Boolean)



    If safe Then

        If Not ws.Name = "COMPLETED" Then

            ws.Columns("A:B").Locked = False

            ws.Columns("D").Locked = False

        End If

        ws.Protect XOREnc("½ ·Î½ ·", "nope")

    Else

        ws.Unprotect XOREnc("½ ·Î½ ·", "nope")

    End If



End Sub



Function XOREnc(theInput As String, theKey As String) As String



    Dim val1, val2 As Integer, out As String, temp As Integer



    For i = 1 To Len(theInput)

        val1 = Asc(Mid(theInput, i, 1))

        val2 = Asc(Mid(theKey, i Mod Len(theKey) + 1, 1))

        If val1 Xor val2 < 32 Then

            temp = 255 - (val1 Xor val2)

        Else

            temp = val1 Xor val2

        End If

        out = out & Chr(temp)

     Next i

     XOREnc = out

End Function

The code is trying to hide a password, -¯-_-¯-. Evidently it is not doing a good job at hiding it, given that I just told you what it is.

Thanks Eric, I forgot to check if anyone had answered and actually got to the solution.
