[DCP-o-matic] Problem with DKDM

Hello from Berlin, Germany. I need help with exporting the necessary data out of dcpomatic in order for a posthouse to make me a DKDM that I can use, to create KDMs for festivals. I’m the director of that movie and we agreed to outsource this process from the posthouse to me to safe a lot of money and time for the KDM creation. I exported the „KDM Encryption Certificate“ as explained in the manual and sent it to the company. They said, they need also a pem file. I didn’t know which file was right, so I exported everything to them what I found under the keys tab. 4 or 5 files. Then they finally made me the DKDM. But when I try to open in in the KDM Creator it failes and warns, that it maybe was made with the wrong certificate. We are lost. Can you help me? Which files are exactly needed in order to create a DKDM and where do I export them?
