Usually you would take the pem files with sha256 in their name. I believe Dolby changed the name from sha256 to SMPTE now for the IMS3000. So I guess the cert you should use for KDM generation is the 371716-SMPTE.pem file. The chain files can be used, but are not necessary.

Other names have been used for previous Dolby and Doremi device types, like DSP100, DSS200 (CAT862), DSS220 (CAT745).
