#9440 closed enhancement (duplicate)

Exhausted available authentication methods. Unrecognised object: OPENSSH PRIVATE KEY.

Priority: high Milestone:
Component: sftp Version: 4.9
Severity: normal Keywords: ed25519 private key
Cc: Architecture: Intel
Platform: Mac OS X 10.11

Description (last modified by kinglok)

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!
