Okay, so if I'm interpreting this correctly.  When the new alg 14 KSKs were created and then the zone was signed (either automatically or via a command) there was probably only a valid alg 8 ZSK available.  As a result bind used the alg 14 KSK as a defacto CSK and singed the zone RRSets directly.

The primary reason that it is per algorithm is that validators and signers are not required to support the same sets of algorithms and if you want validation to work for everyone the zone has to be fully signed for each algorithm that you state that it is signed for, i.e. published in the DS RRset

Re: KSK signing zone records

Named will continually re-sign parts of the zone as the RRSIGs for a RRset fall due for replacement. Named looks at which keys are in the active state to determine along with the afore mentioned controls to work out which DNSKEYs will be used to re-sign the RRset. If in the past you only had

I'm using Algorithm 8 RSA/SHA-256, and Algorithm 14 ECDSA/SHA-384.  I have one RSA KSK and one RSA ZSK.  In addition I have two ECDSA KSK and two ECDSA ZSK.   The RSA KSK seems perfectly happy to sign the ECDSA ZSKs.  And both the RSA and ECDSA ZSKs seem to be singing records correctly.  It just

The rules for what get signed by what are per algorithm. Additionally the SEP bit is hint to the signer as to what is desired. Named has controls to say whether to pay attention to the SEP bit or not. Additionally it will override those controls to pay attention to the SEP but if it believes

What algorithm(s) are you using for ZSK and KSK? If they’re not the same algorithm, then both will be used to sign the entire zone. Regards, Chris Buxton > On Aug 30, 2021, at 9:08 AM, Timothy A. Holtzen via bind-users > wrote: > > Signed PGP part > I've had an issue with my key rotation

KSK signing zone records

2021-08-30 Thread Timothy A. Holtzen via bind-users
I've had an issue with my key rotation process on a couple of zones.  I believe I've resolved that issue but it appears to me in several cases the KSKs rather than being used to sign the ZSK are being used to sign the zone records directly.
