Certificate and CA-Chain

Certificate has a public_key which is not present in any database.

master_pwd.bin and master_pwd_v100.bin

There are two files in /var/lib/docker/overlay2/<nls-container-id>/merged/etc/dls/config. When base64-decoded both files have a length of 256 bytes.

If these files are renamed (adding .bak) NLS stack will come up normally.

Other Code

Interesting is that for encryption the service_instance.deployment Public-Key is used. For that one, we have no private key.
