Could not decrypt KDM

Post by toothpick »

Hello everyone, I have obtained a set of DCP and KDM through some means. However, I am unable to play them in DCP o-matic as it displays (Unable to decrypt KDM (Error: 02000079: rsa Route:: oaep Decoding Error) (256/2048))

I want to know how to play him, please help me

In our country, only any content after the logo of the Film Bureau appears is considered a movie, so my current OST is considered an advertisement, and I have no legal risk

Was the KDM made for your copy of DCP-o-matic? If not, it won't work.

Are you sure the KDM you received is actually targeted towards your own Barco ICMP or DCP-o-matic installation?

KDMs are not universal keys - they only work on a specific device. You can not just copy it to another device and play the content with it.

I also know that some countries have strange special regulations about KDMs, e.g. China.
