I have both rsa and ed25519 keys on my local machine as well as on a remote one. I've also added  both local public keys to authorized_hosts file of a remote machine. When I'm connecting to the remote machine via ssh my_user@server123.com, how do I know whether it's using the rsa or ed25519 key? How can I change that?
How to find out if ssh user@server.com if rsa or ed25519 key is being used if I have both?
linux;ssh
