It's really easy to create a own Intermediate CA with this private key.
Btw. during my investigations I found out that the Manufacturer Public Key is slightly to big to be handled without problems by Haxorware on the 3349 or even on a 3390 based 3.0 CM. So they will not send the Manufacturer Public Key during the BPKM handshake and the BPI process stucks. However, if I use the files on Puma based cable modems it'll work.
