I note that the key label is not set when Knot generates new keys via PKCS#11.
Invoking `p11tool --list-all' shows a key as
Object 449:
URL: pkcs11:model=;manufacturer=nCipher%20Corp.%20Ltd;serial=xxx;\
token=YYY;\
id=%04%66%D0%9C%0D%9E%24%D9%79%0A%17%D3%5D%A0%CC%5A%3F%E2%A3%26;\
type=public
Type: Public key (RSA-2048)
Label:
ID: 04:66:d0:9c:0d:9e:24:d9:79:0a:17:d3:5d:a0:cc:5a:3f:e2:a3:26
The ID is that which `keymgr list' displays (with colons in it), but the label
is empty.
Is this by design? Would it be possible for Knot to actually set the label
(e.g. zone name - key type: example.com-ksk)?

The documentation for `keymgr' says that the subcommand `del-all-old' is
related to offline KSK, but it also seems to work for online KSK.
Moments ago I had the following keys of which e381* had just been marked as
removed:
$ keymgr -c knot.conf tm list -b iso
e381198aea254a1dbceb3c5b153cbefaa98c959a 31943 KSK ECDSAP256SHA256 publish=2022-05-12T11:43:56Z ready=2022-05-12T11:43:56Z active=2022-05-12T11:43:56Z retire=2022-05-12T12:35:42Z revoke=2022-05-12T12:33:42Z remove=2022-05-12T12:37:42Z

$ keymgr -c knot.conf tm del-all-old
OK
$ keymgr -c knot.conf tm list -b iso
d68e6803daa3e3ee34dd07d6966df0c402594fb2 26288 ZSK ECDSAP256SHA256 publish=2022-05-12T12:28:18Z active=2022-05-12T12:28:18Z

and the PEM key file has also been removed.
Is this to be expected? Would it be a good idea to add a note to the
documentation clarifying this?

Hello,
I'd like to be able to do automatic ZSK and manual KSK rollovers. Basically the
KSK should have an endless validity but I might want to roll it with
(manually-trigerred) RFC 5011 semantics.
It it permissible to have a policy such as shown below and then explicitly
use `keymgr' commands to generate new keys and set `revoke', `retire' and
`remove' timers on the older key?
Testing indicates that it works as desired, I'm just unsure whether key
manipulation is permitted.
policy:
- id: autoHSM
keystore: pemstore
single-type-signing: off
manual: off
ksk-shared: off
ksk-lifetime: 0
zsk-lifetime: 30d
cds-cdnskey-publish: rollover
Thank you,
-JP
Hello,
keymgr(8) lists keys in plain text which is fine for processing with awk(1)
et.al. Are there any plans to make it output JSON? I'm thinking along the lines
of making parsing future-proof:
[
{
"id": "a982d72174a48a3ef083a97e5aae02cc47f58762",
"ksk": true,
"zsk": false,
"key_tag": 61676,
"algo": 8,
"size": 2048,
"public-only": false,
"pre-active": 0,
"publish": 1652161461,
"ready": 1652161581,
"active": 1652161642,
"retire-active": 1652168902,
"retire": 0,
"post-active": 0,
"revoke": 0,
"remove": 1652168962
}
]
keymgr_list_keys() calls either of print_key_full() / print_key_brief() to do
the work, and I think it would be quite easy to add support for JSON.
Is this something I should make happen?

Hello,
I need to migrate away from an HSM-backed OpenDNSSEC installation which uses a
Thales nCipher for key storage and am experimenting with Knot DNS 3.1.8 (on
CentOS 7, FWIW).
I've compiled Knot, and it is able to access said HSM via PKCS#11. I have
configured a zone with a manual policy.
policy:
- id: manualHSM
keystore: thales
single-type-signing: on
manual: on
After importing keys from the HSM with `keymgr import-kcs11', knotd launches
and signs the zone with KSK/ZSK as expected.
What I would then like to have happen is to have periodic ZSK rollovers as well
as periodic KSK rollovers. In order to accomplish this I have changed the
zone's policy to
policy:
- id: autoHSM
keystore: thales
single-type-signing: off
manual: off
algorithm: rsasha256
ksk-size: 2048
zsk-size: 1024
zone-max-ttl: 60
dnskey-ttl: 60
propagation-delay: 60
nsec3: on
nsec3-iterations: 0
nsec3-salt-length: 0
nsec3-salt-lifetime: 0
ksk-lifetime: 7200
zsk-lifetime: 3600
A restart of knotd then begins by creating a new ZSK and rolling it, and the
KSK is rolled automatically after 7200 seconds. (These timers are for testing
only.)
So far no complaints whatsoever -- this is working exactly as I had hoped it
would. I am assuming that it is permissible to change a zone's policy in flight.
What I'd like is confirmation that the KSK roll will actually never occur
immediately, but only after a first period has elapsed.
Can I rely on this behavior, i.e. that the first KSK roll will occur only after
a first `ksk-lifetime' period?
Best regards,
-JP
