Converting the sign key from hex to byte format.

[martin-naumann]

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..

Have you tested this? As far as I can see, this will not work (you're calling a function not an object method)...

Maybe you can also add some documentation/screeshot of the management interface?

[martin-naumann]

You're right about the glitch in the second call. It obviously has to be a method call.

A screenshot? To show what? Nothing changed in the management interface.
And where to put docs? There is no documentation all over the place (apart from some comments in the code, where I added a little documentation comment for the method now)

Either a README.md file, or using the Wiki functionality on GitHub?

Et voilà.
Now there is a note in the English and German translations for the backend PLUS a note in the README.txt.
