If your company uses private keys, you can use them for server or mutual authentication between the services in a Collibra Platform environment, provided that they meet the specifications.
If they do not meet the specifications, you can convert the keys with the following command:
openssl pkcs8 -topk8 \ -inform PEM \ -outform PEM \ -in <path_to_original_key> \ -nocrypt \ -out <path_to_new_key>
