I Have Question in Fido2 Server Using

[Saebyeol98]

Hello. There was a question while installing the fido2 server.

First. Question

Please look at this picture

This is a certificate for your demo server, demo.strongkey.com.

Please look at this picture next.

When I installed the strongkey fido2 server on my server, I can access the certificate information as shown in the picture above.

As shown in the picture below, I already have an https certificate issued by Let's Encrpyt.

I went into https://docs.strongkey.com/ and searched everything, but there was no guideline for the certificate replacement part.

I want to register the certificate I issued on the server and use it.
Please give me some advice on how to do this.

Second. Question

I am creating the StrongKey Authenticate App for my service based on the SACL Android example.

As shown in the picture below,

The project contains the files required for self-signing before connecting to the server. I'd like to replace this with the file that my server uses. Should I put the rootCA file among the files made by Let's Encrypt?
