beispiele:
- validierung klappt ueber dlv aber nicht ueber "normal"
pro zone 1 oder mehr keys - darf zur zeit nur RSASHA1 sein: bind 9.7 manual 4.8.1:
It is recommended that zone keys use a cryptographic algorithm designated as ”mandatory to implement” by the IETF; currently the only one is RSASHA1.
The following command will generate a 768-bit RSASHA1 key for the child.example zone:
dnssec-keygen -a RSASHA1 -b 768 -n ZONE child.example.
