I understand your decision to push people towards RFC 9276.

As said I was debugging NSEC3 issues of a zone which currently uses a salt, and I wanted to reproduce the same hasing as those zone currently use. So I do not want to use a salt in production, but only in testing.

So I am fine with the workaround of doing manual signing with dnssec-signzone.

PS: All of nic.at/RcodeZero is using RFC 9276.
