New description:

 I created my private key in these ways in my server:
 ------------
 ssh-keygen -t ed25519 -o -a 100

 ssh-keygen -t rsa -b 4096 -o -a 100
 ------------

 When authenticating my server using the keys respectively, Cyberduck said:
 "Exhausted available authentication methods. Unrecognised object: OPENSSH
 PRIVATE KEY."

 Please consider recognise these keys type which provides very secure way
 in logging the server.

 Thanks a lot!
