Here is an utility for translating permission masks in hex to SPBasePermissions values.Click below to download.





The core of the thing:

private void button1_Click(object sender, EventArgs e)
        {
            string userValue = textBox1.Text;
            listBox1.Items.Clear();
            long valueOriginal = long.Parse(userValue, NumberStyles.AllowHexSpecifier);
            long value = valueOriginal;
            int rbit = 0;
            do
            {
                int i = (int)(value % 2);
                long bitcheck = 1 << rbit;
                if (i > 0) // it matches
                {
                    string name = "" + ((SPBasePermissions)bitcheck);
                    string formatString = String.Format("{0,10:X}", bitcheck);
                    Console.WriteLine(name + " " + formatString);
                    listBox1.Items.Add(name + " " + formatString);
                }

                value = value >> 1;
                rbit++;
            } while (value > 0);
        }
