#9440: Cyberduck should accept secure private key authentication
----------------------------+---------------------------------
    Reporter:  kinglok      |      Owner:
        Type:  enhancement  |     Status:  new
    Priority:  high         |  Milestone:  5.0
   Component:  core         |    Version:  4.9
    Severity:  normal       |   Keywords:  ed25519 private key
Architecture:  Intel        |   Platform:  Mac OS X 10.11
----------------------------+---------------------------------
 I created my private key in these ways in my server:
 ------------
 ssh-keygen -t ed25519 -f my_host_ed25519_key

 ssh-keygen -t rsa -b 4096 -f my_host_rsa_key
 ------------

 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!
