My experience with changing the timing metadata or removing the key files is that named issues a warning like the following: zone zone/IN: Key zone/algorithm/key tag missing or inactive and has no replacement: retaining signatures. In this circumstance none of the RRSIGs or NSECs are

Hello. I don't think that bind trying to sign with non-existent key will do any harm - probably just warning. But it's simpler - change metadata of the key - set deletion time to the time you want the key to be deleted (like DS deletion time+TTL). Bind with auto-dnnsec allow re-reads the metadata

I discovered that if there was not at least one KSK and ZSK of the same algorithm, dnssec-signzone would fail. If one goes with defaults, KSK life of one year and ZSK of one month, effectively to roll a key algorithm and without forcing the roll-over by removing all the old key/algorithm at

I propose the following addition to the Bv9ARM, and request review and comment by the experts on this list. -- 4.9.14 DNSKEY Algorithm Rollover From time to time new digital signature algorithms with improved security are introduced, and it may be desirable for administrators to roll
