At the top of the tab is the chain of certificates that will be used
to sign DCPs and KDMs. DCP-o-matic creates a random chain when you

-you can ignore the preferences. Otherwise, you can add or remove
-certificates from the chain using the <guilabel>Add...</guilabel> and

-DCP-o-matic. If you want to import an encrypted DCP you will need to

-they can generate a DKDM for you. As with the certificate chain,
-DCP-o-matic will create a certificate and private key for you. You
-can also choose to load your own certificate and key.
