Specify the algorithm to use for calculating hash.
DS-record(s) to be included in parent zone\
The DS-record(s) needed to be included (and signed) in the parent zone. For example if your domain name is "example.se", the DS-record needs to be added to the ".se" zone. The procedure for "uploading" the DS-record depends on your parent zone / TLD operator, and/or your domain name registrar.
