VB.Net to VB6 Conversion

Hi Experts,

Can anyone convert the following code to VB6?  

Private Function SHA256File(ByVal input As String) As String
        Dim rdr As FileStream
        Dim sha As New SHA256Managed
        Dim bytes() As Byte
        Dim output As String = ""
        If File.Exists(input) Then
            rdr = New FileStream(input, FileMode.Open, FileAccess.Read)
            bytes = sha.ComputeHash(rdr)
            For Each b As Byte In bytes
                output += b.ToString("x2")
            Next
        End If
        Return output
    End Function

Thanking you,
