Obtain a Hash from a Excel 2007 file

[taratota]

Works fine! (So I think although I have not checked it)
This is the output for my test-Excel: excel-test.xlsx:$office$*2007*20*128*16*93da6e1d346c793d821daf7877d440ff*fdad25c4a27cb26816602397a55e0755*decc89fa6d72b495cac8ced2e66dfca26d4b44111d1def88becd82b749fca647

I don't understand yet de format of this string, but I will investigate this
