> Hi,
> The JSch library used for SFTP does not support HostKeyAlgorithms=ed25519 whereas it is the current standard. This make SFTP / SSH unusable when dealing with recent openssh config.
> On dbeaver project they switched to sshj.

> One more argument against JSch is that it does not support rsa key length other than default (2048).
> ssh-keygen -o -t rsa -b 4096 -f id_rsa -> does not work with nifi
> ssh-keygen -t rsa -f id_rsa -> works with nifi
> Thanks and regards

> PS : sorry but I do not know nifi deep enough to fill all fields.
