[Opendnssec-user] Re: NSEC3PARAM and OPTOUT

This is by design.

I see there are at least 3 TLDs which I know are using ODS and where the NSEC3PARAM indicates OPT-OUT disabled, but the NSEC3 records have OPT-OUT flag enabled. When using BIND to sign a zone, both NSEC3PARAM and NSEC3 have the flags set the same way. Is it me missing something or is it that by design?
Thanks.

Hello,

This one is easy to reproduce.
ods-ksmutil -V
opendnssec version 1.4.6

>From kasp.xml:
                <Denial>
                        <NSEC3>
                                <OptOut/>
                                <Resalt>P100D</Resalt>
                                <Hash>
                                        <Algorithm>1</Algorithm>
                                        <Iterations>10</Iterations>
                                        <Salt length="8"/>
                                </Hash>
                        </NSEC3>
                </Denial>

When the zonefile is signed, the NSEC3PARAM flag indicates OPT-OUT disabled (when it's enabled in the configuration).

test.org<http://test.org>.       0       IN      NSEC3PARAM      1 0 10 e5d234b3dc0e03a3

The NSEC3 records though have it right.

pufepsta7kv6r1uo2t3nchdkqpdhaqak.test.org<http://pufepsta7kv6r1uo2t3nchdkqpdhaqak.test.org>.      86400   IN      NSEC3   1 1 10 e5d234b3dc0e03a3  8a2j6ietl8fhltcfp1l25mf7qfu6dt69 A NS SOA MX RRSIG DNSKEY NSEC3PARAM

Can someone else confirm that behavior?

Happy holidays,
Emil
