This method needs to be consistent and as part of the method, the length is set. In previous versions, this length isn't set, but starting from Pi, it is. What this means is that decryption of the device keys fails, and therefore offline licenses are lost. As a workaround, we attempt to decrypt the device keys with the length parameter and with the default if we failed to decrypt. Since the generation number is also encrypted by the unique id, in the case where we succeed in decrypting with the default, we reencrypt the generation number so it can be read in when we handle the usage table. Finally, we reencrypt everything with the correct length unique id. Change-Id: Id682771c3921dea35592914fc7a1aaa92fa6737a
