Thus, I am notifying you that we intend to end support for the "nsec3 salt-length" (inside dnssec-policy) option in named. Our plan is to mark them as deprecated in BIND 9.20, and remove them completely as of BIND 9.22.
@ https://bind9.readthedocs.io/en/latest/dnssec-guide.html#advanced-discussions-nsec3-salt there's no reference to a literal "nsec3 salt-length" rather, usage in policy of "nsec3param ..." nsec3param iterations 0 optout no salt-length 0; just to confirm, the removal will then require - nsec3param iterations 0 optout no salt-length 0; + nsec3param iterations 0 optout no; ? with the salt-length hardwired == 0? -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list.
