And do you also know where kobo writes its code in kepub files?
Pretty much through all the text files for the spans and javascript code. For DRMmed files, you will find rights.xml in the root of the zip container. A kepub with DRM is encrypted for the device.

For Kobo ereaders, the decryption key is based on the serial number unlike Adobe ADEPT DRM where the decryption key is based on the user ID so two devices with the same user ID can share files. For Kobo ereaders, you have to download the ebook to the device it will be read on.
