dnssec-key 'unknown algorithm RSASHA512'

[Petr Menšík]

Oh, please do not forget to generate new my-tsig after sharing your 
current with all of us.

Next time please use named-checkconf -px named.conf.tsigkeys to filter 
out secrets.

As Anand already wrote, shared keys are not asymmetric keys generated by 
dnssec-keygen. That have been split since 9.16 into separate generators 
focused only on shared keys. Use tsig-keygen or ddns-confgen to create 
shared keys. dnssec-keygen is now only for generating keys with .private 
part, which are used in DNSSEC signing only, used in zone files. Usually 
not for anything related to ACLs, as for example dynamic updates. 
ddns-confgen is exactly for that.

Cheers, Petr
