This explains how to get a zone signed with DNSSEC in Sweden with the help of Frobbit!
If Frobbit! is Registrar for your .se-domain and runs DNS for your zone you automatically have DNSSEC and don´t need to do anything.
If you run DNS yourself, you have to go through a few more steps. Look through all of them, and specifically, you should know how you should run DNSSEC before you ask for the DNSSEC service to be added.
Make sure Frobbit! is Registrar for the domain. If not, start with sending an email to info@frobbit.se and ask for a Registrar Transfer to Frobbit! and inform us at the same time that you would like DNSSEC.
Frobbit! will inform you how to get the authorization code needed from you current Registrar and when we have the code we will first transfer the domain to us.
Frobbit! will then activate DNSSEC for the domain, and report to you when this is done.
Sign your zone, and publish it. See for example the excellent information by NLNetLabs on how to do it. Important commands (in a unix environment) are (once, to create the keys) dnssec-keygen and (whenever you change the zone) dnssec-signzone.
