I had to replace the dolphin board in a Doremi DCP2000 today. This also changes the esn on on the server.
This server is not in a regular, commercial theater situation, so I have no encrypted content to test with, nor does this location have any relationship with the studios or bookers where I can get them to send me anything.
Using DCP-o-Matic, (which I've used many times before) I've created an encrypted test file. I've also downloaded the certificates from Doremi for the new esn in my serverthingy. But there are 6 certificates. Which one(s?) do I use to generate the KDM in DCP-oh-Matic?
The certificate files look like this: (Obviously, I've removed the actual server serial #)
File 1) dcp2000-12345-01.cert.mpeg.pem 2) dcp2000-12345-01.chain.mpeg.pem 3) dcp2000-12345-01.cert.sha1.pem 4) dcp2000-12345-01.chain.sha1.pem 5) dcp2000-12345-01.cert.sha256.pem 6 dcp-2000-12345-01.chain.sha256.pem
So, which one do I use? (And what's the difference?)
The projector is a Series 1 NEC, but I forget the model number.
I'm going to need to play "real" encrypted content in about a week, but I want to test before then, and I'm not getting any cooperation from the film distributors in trying to get some content and KDM's sent early . So I need to generate my own encrypted content to test.
Non-encrypted and alternate inputstuff is playing fine.
(and, "yes" I've informed Deluxe/Technicolor and the other content providers we deal with of the change in the server ESN.)

Thanks Carsten & Dave. Actually, since this was keeping me awake last night, I did a lot of online searching & reading and was able to determine which was the proper certificate to use for KDM generation.
For some reason the 'automatic' Doremi certificate finder on my version of DCP-O-Matic couldn't fetch the certificate on it's own, but I have a feeling that was due to the firewall I was behind.
Dave- I was aware of the STEM file, the server I was working on was several years old, and had been moved from another location. It was in storage for about two years, so the CMOS battery had gone dead and then when I replaced it I had to re-enter all the bios settings, drive ID's & boot order, etc. Then, I couldn't get the dolphin board & secure clock function, even with a new battery. ( I think the old one had been dead for too long)
I was able to get a new dolphin board, and all the latest software upgrades, and the good news is that the encrypted test DCP's and KDM's I generated last night worked without any problems when I went in and tried them this morning. So, problem (apparently) solved!
