When I connect to my Dropbear SSH server for the first time, I get the following message:

me@laptop:~$ ssh me@server
The authenticity of host 'server' can't be established.
RSA key fingerprint is SHA256:NycCxoRiiSAGA7Rvlnuf1gU8pazIpXJKZ3ukdivyam8.
Are you sure you want to continue connecting (yes/no)?

To make sure that this is the correct server, I want to compare the stated fingerprint from that message to the server's real fingerprint. How can I find out the server's RSA host key fingerprint?
