[KASP] Key rollover

[adrien sipasseuth]

Hello Matthijs,

Indeed I had not published the DS at my registar because I thought that the
second KSK would have appeared anyway at the time of the rollover.

I published the DS yesterday and I reported to BIND with the command you
gave me. I didn't find any error in the logs so everything must have been
fine!

here is the state file of the KSK in use :
; This is the state of key 46358, for ***********************.
Algorithm: 13
Length: 256
Lifetime: 604800
Predecessor: 28887
KSK: yes
ZSK: no
Generated: 20230117165503 (Tue Jan 17 17:55:03 2023)
Published: 20230117165503 (Tue Jan 17 17:55:03 2023)

DNSKEYState: omnipresent

>From my understanding, the second KSK should appear because I put the
parameter "publish-safety 3d;" that is to say 3 days before the expiration
("retired") of the key in use. is that right?

that is to say tonight at 7pm, I will see tomorrow if this one appears.

regards, Adrien
