Hi Carl,
I had encrypted SMPTE problems also with Doremi servers.
Come now ... tell me more!
Carl
I'm sure for an IMS DOREMI with 2.6.6 version software and i think with
DCP 2000.

Thanks everyone for the help. It turns out the
mastering facility used the signing keys instead of the decrypting keys.
The DKDM issued with the decrypting keys works.
Interestingly, this did uncover a crash situation.
1. I created a new project
2. I imported the DCP using "Add Folder..."
3. Right clicked on the DCP in the content window selected Add KDM
4. Selected the original KDM the mastering facility incorrectly produced.
5. I receive the "An exception occurred: Could not decrypt KDM (error:0407A079:rsa
routines:RSA_padding_check_PKCS1_OAEP:oaep decoding error)." error message
6. I clicked back on the imported DCP in the content window, and DoM crashed.
This happened in 2.9.0 and 2.10.2 running on macOS Sierra 10.12.2.
When I have a second today, I'll download the test build and see if it happens there
as well.
Thanks Tom, I believe this bug is already on the to-do list. I will
investigate.
All the best,
Carl

At the moment it looks like the DKDM was issued against the signing veers and not
the decrypting certainty.

I remember that I had an issue after I had been working with, and updating
DCP-o-matic for a long time on the same machine. I couldn't issue
working certificates for a DKDM.
'Recreate certificates and keys' solved that issue. Something in
preferences must have been mixed up over so many version updates.
However, I guess before doing that, exporting the current chain and saving it
under a name of the current date and DOM version before that may be
a good idea. Depends on what you had been working on before.

Hi Manuel,
I think, on the whole, I'd like to wait a little longer: at least until
we've got to the bottom of the encrypted SMPTE problems with Sony systems.
It's interesting to hear the state of the US big releases though: thanks!
Regards,
Carl

Just seeing the numbers from wide releases in US.
Basically, non-SMPTE theaters are not relevant anymore. Some major studios are already
nearly fully SMPTE,
theaters that didn't do the minimal updates will do them now, for sure.
I would insist in going back to default to SMPTE as the standard for new installs.
