How to import existing FW certificate?

Hi Vertical Technik ,

Thank you for reaching out to the community, yes as of now CSRs is a must, REF - Import a certificate . Not sure if a re-naming of an extension help ?
But .CSR contains information such as the public key and common name required by a Certificate Authority to create and sign a certificate for the requester, the encoding could be PEM or DER (which is a binary encoding of an ASN.1 specified structure); Where as .CRT stands simply for certificate, usually an X509v3 certificate, again the encoding could be PEM or DER; a certificate contains the public key, but it contains much more information (most importantly the signature by the Certificate Authority over the data and public key, of course).

Thank you for your answer.. I am totally new to Firewalls and trying to learn everything about it.

Maybe you can provide me the following informations:

1. how can I find out who (company) has provided our current working Firewall Certificate?

2. is the CSR file a new standard since 2023/2024?

Many thanks again for any clarification about this topic.

Tim

can you please help clarify if the new FW has the default CA up to date under the Certificate > Certificate authorities >  Default ?
