Ability to generate new private key when renewing Certificate.

DOMINO 12.0.2FP3


Customer use a 3rd party CA.


There is no issue creating new certificates. Issue is with renewal. Our CA does not allow reuse of the private key when pasting in the CSR. I am unable to generate a new key pair in the certstore.nsf credential doc for a renewal CSR. I have tried "Request key rollover", but the CSR remains the same. The only thing I have found that works is to delete the certificate in Domino and start from scratch.

Customer is requesting the ability to create a new private key when renewing a certificate.

    Creating a new private key is problematic.
    We would need to have a pending new key and can't replace the key.

    The CSR flow is a manual process which is not end to end automated, because of the nature of external CAs.

    The best way is to create a new TLS credentials document with a new key and once the certificate is merged, delete the old TLS Credentials document or let it expire.

    If we would change the key and the operation takes a while, you end up with no valid TLS Credentials document.
    With ACME the operation works differently. We create the new key and CSR on the fly during the ACME flow.
    That allows us to roll over the key.

    The manual flow is a two step process in contrast with an unknown time delay. It could take days until the Domino team gets a certificate from another department.

    Creating a draft new key would need a lot of new logic, which would confuse admins more than it would help.

    IMHO having a new TLS Credentials document makes more sense to keep it clean.

    If you want this type of flow and need the pending new key in the same document, that is a very specific request.
    If there are no other customers who would need this option for the manual flow, we would need more customers requesting it.

    For now you can just copy the settings from one document to a new document and create a new key.
    Once done expire the existing document.

    This can be automated with an own agent.
