Title: Converting the sign key from hex to byte format.

The UPP admin interface only gives you the sign key in hex format and just says "You need to convert it" but gives no directions on how to do that.
The new method convertHexToByteString automatically does it, so that you can just paste the sign key as it is presented by the UPP interface into the Isotope configuration page and live happily ever after..
