[knot-dns-users] Failure importing a public key from BIND

I am trying to import a public key generated by BIND into Knot, when using the SoftHSM2 key store. I have the following pieces of information: In my knot.conf file: policy: - id: SoftHSMRSAPolicy algorithm: RSASHA256 ksk-size: 2048 zsk-size: 2048 ksk-lifetime: 7h zsk-lifetime: 6h dnskey-ttl: 12s zone-max-ttl: 15s keystore: SoftHSM zone: - domain: 00.mydomain.com storage: /srv/knot file: db.mydomain00 dnssec-signing: on dnssec-policy: SoftHSMRSAPolicy The public key is in a file named pubkey, and has the following contents: ; This is a zone-signing key, keyid 14694, for 00.mydomain.com. ; Created: 20211109192137 (Tue Nov 9 12:21:37 2021) ; Publish: 20211109192137 (Tue Nov 9 12:21:37 2021) ; Activate: 20211109192137 (Tue Nov 9 12:21:37 2021) 00.mydomain.com.
