kinglok created the issue

Cyberduck can log myself through SFTP protocol with using ed25519 private key. However, if a ed25519 key is password-protected, Cyberduck cannot login the same server but showing the following error message:

Exhausted available authentication methods. Please contact your web hosting service provider for assistance.

Hi,
Updated the App (via App Store) and unfortunately, it still not working. Getting the following error: "Exhausted available authentication methods. Unknown key type ssh-ed25519. Please contact your web hosting service provider for assistance."
However, it seems working fine with the nightly builds.
Thanks.

Correct
I am unable to reproduce with a key generated using ssh-keygen -t ed25519 running 6.6.2 (28219).
I’ve generated it in Putty (Windows).

Then how you explain that it works fine in nightly built?
The key is working fine in other Windows/macOS applications (e.g. Yummy FTP Pro, Putty etc.)

I have recreated a key via macOS terminal and can confirm that it’s working now. It seems that there is an issue with Putty keys. Thanks.

Can you please try re-selecting the PuTTY private key in the bookmark settings and try to connect again.

I've tried all possible scenarios - reinstalling the app, re-creating bookmarks, re-choosing the key, however, unfortunately, it's still not working. Gonna stick to the newly created key (via ssh-keygen), was able to convert the new key to the Putty format using puttygen nightly build.
Thanks.

Hi,

I use the following the command to create the private/public key pair for logging my Debian server.

ssh-keygen -t ed25519 -f ssh_host_ed25519_key

While using the latest snapshot of Cyberduck and come across with “Application error”.

please advise how I can help by fixing it up.

Thanks,

Kinglok, Fong

I am using the latest snapshot of Cyberduck.

The screen shows "Unknown application error" and I have attached the log file.
The error log suggests that the server is dropping the connection while trying to authenticate. Please check the server log for possible reasons.

Things are getting better but this time produce another type of error:
Connection failed
Login failed. The connection attempt was rejected. The server may be down, or your network may not be properly configured.

I have attached the server-side log for your comment.

I had the same issue in Windows using a .ppk PuTTY key, but I was able work around it by opening it up in PuTTYgen, then choosing Conversions > Export OpenSSH key (force new file format) from the menu, saving it with a .pem extension, then using that in Cyberduck.

this is not fixed, i just got it again with cyberduck 7.4.1 on windows 10, with a ed25519 key generated by putty. If i use the putty private key as the 'ssh private key', it doesn't work with the "login failed: exhausted available authentication methods, unknown key type ssh-ed25519"

attached is the openssh debug3 logs

Did you check the wiki page? https://trac.cyberduck.io/wiki/help/en/howto/sftp#PuTTYKeyFormatInteroperability
There is no support for ed25519 keys in PuTTy format. Please use OpenSSH keys.

6b44c9e commented

is there a ticket for having cyberduck support putty keys with ed25519 keys? or for having a prompt saying "please use openssh ed25519 keys"? that article did not show up on google when searching for the error message cyberduck shows when using a putty ed25519 key if for some reason it is impossible for cyberduck to support it?
