Labo cannot read Certificate and wants ChainCert format.

Post by EdouardPoutelatiche »

Hello everyone,

I have to do versionning on a japanese movie that is encrypted and sent a Certificate generated by DCP-o-matic to the Labo.
It's my first time accepting encrypted DCPs.
I sent the file "dcpomatic_kdm_decryption_cert_COMPUTER.pem" to them and they replied
that they cannot read the certificate and that I need to send another format that is called "ChainCert"
which includes material info.

Does anyone know how I do this ? I found no information on ChainCert for KDMs. Just some Blockchain stuff, which I know nothing about.

Perhaps they want the full certificate chain rather than just the leaf certificate? You can get that by clicking "Advanced..." under "Decrypting KDMs" in the preferences and then clicking "Export chain..."
